The mushrooms have been valued at 25 cents per pound, which is probably

considerably below the average market price for a good article. It

should also be remarked that the amounts given in this table are the

digestible and hence available constituents of the foods. The only

exception to this is in the case of the fats and carbohydrates of the

mushrooms, no digestion experiments having been reported on these

constituents. In the absence of data we have assumed that they were

entirely digested.

The beef and beans are typical animal and vegetable foods of the proteid

class. A glance at the table will show how markedly they differ from the

mushrooms. The latter are nearest the cabbage in composition and

nutritive value. The similarity between the cabbage and the _Agaricus

campestris_ here analyzed is very striking. The potato is somewhat

poorer in fat, but very much richer than the mushroom in carbohydrates.

The figures in the last column will vary of course with fluctuations in

the market price, but such variation will not interfere at any time with

the demonstration that _purchased_ mushrooms are not a poor man's food.

Here we find that one cent invested in cabbage at 1-1/2 cents per pound,

gives 93 _calories_ of nutrition, while the same amount invested in

_Agaricus campestris_--the common mushroom of our markets--would give

but 5.3 _calories_, although they are almost identical so far as

nutritive value is concerned.

The same sum invested in wheat flour, with its high carbohydrate and

good proteid content, would yield 658 _calories_ or one-sixth the amount

necessary to sustain a man at work for one day. The amount of mushrooms

necessary for the same result is a matter of simple computation.

Mushrooms, however, have a distinct and very great value as a food of

the third class, that is, as condiments or food accessories, and their

value as such is beyond the computation of the chemist or the

physiologist, and doubtless varies with different individuals. They are

among the most appetizing of table delicacies and add greatly to the

palatability of many foods when cooked with them. It is surely as unfair

to decry the mushroom on account of its low nutritive value, as it is

wrong to attribute to it qualities which are nothing short of absurd in

view of its composition. In some respects its place as a food is not

unlike that of the oyster, celery, berries, and other delicacies. Worked

out on the basis of nutritive value alone they would all be condemned;

the oyster for instance presents a showing but little better than the

mushroom, and vastly inferior, so far as economy is concerned, to the

common potato. This, too, for oysters purchased by the quart. The

nutritive value of one cent's worth of oysters "on the half shell" would

be interesting!

The question of the toxicology of the higher fungi is one of very great

theoretical and practical interest. But on account of the great

difficulties in the way of such investigations comparatively little has

yet been accomplished. A few toxic compounds belonging chiefly to the

class termed alkaloids have, however, been definitely isolated.

=Choline.=--This alkaloid is of wide occurrence in the animal and

vegetable kingdoms. It has been isolated from _Amanita muscaria_, _A.

pantherina_, _Boletus luridus_, and _Helvella esculenta_. It is not very

toxic, but on uniting with oxygen it passes over to muscarine. According

to Kobert the substance formed from choline on the decay of the

mushrooms containing it is not muscarine, but a very closely related

alkaloid, _neurin_. This transformation of a comparatively harmless

alkaloid to an extremely deadly one simply by the partial decay of the

plant in which the former is normally found, emphasizes very much the

wisdom of rejecting for table use all specimens which are not entirely

fresh. This advice applies to all kinds of mushrooms, and to worm-eaten

and otherwise injured, as well as decayed ones. Neurin is almost

identical in its physiological effects with muscarine, which is

described below.

=Muscarine.=--This is the most important because the most dangerous

alkaloid found in the mushrooms. It is most abundant in _Amanita

muscaria_, it is also found in considerable quantity in _Amanita

pantherina_, and to a lesser, but still very dangerous extent in

_Boletus luridus_ and _Russula emetica_. It is quite probably identical

with bulbosine, isolated from _Amanita phalloides_ by Boudier.

_Muscarine_ is an extremely violent poison, .003 to .005 of a gram (.06

grain) being a very dangerous dose for a man. Like other constituents of

mushrooms, the amount of muscarine present varies very greatly with

varying conditions of soil and climate. This, indeed, may account for

the fact that _Boletus luridus_ is regarded as an edible mushroom in

certain parts of Europe, the environment being such that little or no

muscarine is developed.

According to Kobert, _Amanita muscaria_ contains, besides choline and

muscarine, a third alkaloid, _pilz-atropin_. This alkaloid, like

ordinary atropin, neutralizes to a greater or less extent the muscarine.

The amount of pilz-atropin present varies, as other constituents of

mushrooms vary, with varying conditions of soil, climate, etc., and it

may be that in those localities where the _Amanita muscaria_ is used for

food the conditions are favorable for a large production of pilz-atropin

which neutralizes the muscarine, thus making the plant harmless. Be

this as it may, _Amanita muscaria_, so deadly as ordinarily found, is

undoubtedly used quite largely as food in parts of France and Russia,

and it has been eaten repeatedly in certain localities in this country

without harm.

Fortunately muscarine has a very unpleasant taste. It is interesting in

this connection to note that the _Amanita muscaria_ is said to be used

by the inhabitants of Northern Russia--particularly the Koraks--as a

means of inducing intoxication. To overcome the extremely unpleasant

taste of the plant they swallow pieces of the dried cap without chewing

them, or boil them in water and drink the decoction with other

substances which disguise the taste.

The symptoms of poisoning with muscarine are not at once evident, as is

the case with several of the less virulent poisons. They usually appear

in from one-half to two hours. For the symptoms in detail we shall quote

from Mr. V. K. Chestnut, Dept. of Agr., Washington (Circular No. 13,

Div. of Bot.): "Vomiting and diarrhoea almost always occur, with a

pronounced flow of saliva, suppression of the urine, and various

cerebral phenomena beginning with giddiness, loss of confidence in one's

ability to make ordinary movements, and derangements of vision. This is

succeeded by stupor, cold sweats, and a very marked weakening of the

heart's action. In case of rapid recovery the stupor is short and

usually marked with mild delirium. In fatal cases the stupor continues

from one to two or three days, and death at last ensues from the gradual

weakening and final stoppage of the heart's action."

The treatment for poisoning by muscarine consists primarily in removing

the unabsorbed portion of the mushroom from the alimentary canal and in

counteracting the effect of muscarine on the heart. The action of this

organ should be fortified at once by the subcutaneous injection, by a

physician, of atropine in doses of from one one-hundredth to

one-fiftieth of a grain. The strongest emetics, such as sulphate of zinc

or apomorphine, should be used, though in case of profound stupor even

these may not produce the desired action. Freshly ignited charcoal or

two grains of a one per cent. alkaline solution of permanganate of

potash may then be administered, in order, in the case of the former

substance, to absorb the poison, or, in the case of the latter, to

decompose it. This should be followed by oils or oleaginous purgatives,

and the intestines should be cleaned and washed out with an enema of

warm water and turpentine.

Experiments on animals poisoned by _Amanita muscaria_ and with pure

muscarine show very clearly that when the heart has nearly ceased to

beat it may be stimulated to strong action almost instantly by the use

of atropine. Its use as thus demonstrated has been the means of saving

numerous lives. We have in this alkaloid an almost perfect physiological

antidote for muscarine, and therefore in such cases of poisoning its use

should be pushed as heroically as the symptoms of the case will warrant.

The presence of phallin in _Amanita muscaria_ is possible, and its

symptoms should be looked for in the red color of the blood serum

discharged from the intestines.

=Phallin.=--The exact chemical nature of this extremely toxic substance

is not certainly known, but it is generally conceded to be of an

albuminous nature. That it is an extremely deadly poison is shown by the

fact that .0015 grain per 2 lbs. weight of the animal is a fatal dose

for cats and dogs. It is the active principle of the most deadly of all

mushrooms, the _Amanita phalloides_, or death-cup fungus. We quote again

from Mr. Chestnut's account of phallin and its treatment: "The

fundamental injury is not due, as in the case of muscarine, to a

paralysis of the nerves controlling the action of the heart, but to a

direct effect on the blood corpuscles. These are quickly dissolved by

phallin, the blood serum escaping from the blood vessels into the

alimentary canal, and the whole system being rapidly drained of its

vitality. No bad taste warns the victim, nor do the preliminary symptoms

begin until nine to fourteen hours after the poisonous mushrooms are

eaten. There is then considerable abdominal pain and there may be cramps

in the legs and other nervous phenomena, such as convulsions, and even

lockjaw or other kinds of tetanic spasms. The pulse is weak, the

abdominal pain is rapidly followed by nausea, vomiting, and extreme

diarrhoea, the intestinal discharges assuming the 'rice-water'

condition characteristic of cholera. The latter symptoms are

persistently maintained, generally without loss of consciousness, until

death ensues, which happens in from two to four days. There is no known

antidote by which the effects of phallin can be counteracted. The

undigested material, if not already vomited, should, however, be removed

from the stomach and intestines by methods similar to those given for

cases of poisoning by _Amanita muscaria_.

"After that the remainder of the poison, if the amount of phallin

already taken up by the system is not too large, may wear itself out on

the blood and the patient may recover. It is suggested that this

wearing-out process may be assisted by transfusing into the veins blood

freshly taken from some warm-blooded animal. The depletion of the blood

serum might be remedied by similar transfusions of salt and warm water."

=Helvellic Acid.=--This very deadly poison is sometimes found in

_Helvella esculenta_ Persoon (Gyromitra esculenta), particularly in old

or decaying specimens. It has been studied and named by Boehm. It is

quite soluble in hot water, and in some localities this species of

_Helvella_ is always parboiled--the water being thrown away--before it

is prepared for the table. It seems to be quite generally agreed that

young and perfectly fresh specimens are free from the poison. As the

poison is very violent, however, this plant should be carefully avoided.

The symptoms resemble in a very marked degree those of the deadly

phallin, the dissolution of the red corpuscles of the blood being one of

the most marked and most dangerous; this is accompanied by nausea,

vomiting, jaundice, and stoppage of the kidneys. There is no known

antidote for this poison, hence the little that can be done would be

similar to that mentioned under phallin.

When poisoning by mushrooms is suspected, one cannot too strongly urge

that the services of a competent physician should be secured with the

least possible delay.

CHAPTER XXIII.

DESCRIPTION OF TERMS APPLIED TO CERTAIN STRUCTURAL CHARACTERS OF

MUSHROOMS.

By H. HASSELBRING.

In fungi, as in higher plants, each organ or part of the plant is

subject to a great number of variations which appeal to the eye of the

student, and by which he recognizes relationship among the various

individuals, species, and genera of this group. For the purpose of

systematic studies of mushrooms or even for the recognition of a few

species, it is of primary importance to be acquainted with terms used in

describing different types of variation. Only a few of the more

important terms, such as are employed in this book, together with

diagrams illustrating typical cases to which they are applied, will be

given here.

=The pileus.=--The _pileus_ or _cap_ is the first part of a mushroom

which attracts the attention of the collector. It is the fleshy fruit

body of the plant. This, like all other parts of the mushroom, is made

up, not of cellular tissue as we find it in flowering plants, but of

numerous interwoven threads, called _hyphæ_, which constitute the flesh

or _trama_ of the pileus. Ordinarily, the filamentous structure of the

flesh is very obvious when a thin section of the cap is examined under

the microscope, but in certain genera, as _Russula_ and _Lactarius_,

many branches of the _hyphæ_ become greatly enlarged, forming little

vesicles or bladders. These vesicles lie in groups all through the flesh

of the pileus, sometimes forming the greater part of its substance. The

filamentous _hyphæ_ pass around and through these groups, filling up the

interstices. In cross section this tissue resembles parenchyma, and

appears as if it were made up of rounded cells. Such a trama is said to

be _vesiculose_ to distinguish it from the ordinary or _floccose_ trama.

The threads on the outer surface of the pileus constitute the cortex or

cuticle. They are thick walled and often contain coloring matter which

gives the plants their characteristic color. In many species their walls

become gelatinized, covering the outside of the pileus with a viscid,

slimy, or glutinous layer, often called _pellicle_. In other instances

the corticle layer ceases to grow with the pileus. It is then torn and

split by the continued expanding of the rest of the plant, and remains

on the surface in the form of hairs, fibers, scales, etc.

[Illustration: FIGURE 239. Portion of vesiculose trama in the pileus of

a Russula.]

[Illustration: FIGURE 240. Portion of a floccose trama.]

As an example of the most usual form of the pileus, we may take that of

the common mushroom (_Agaricus campestris_) when it is nearly expanded.

The pileus is then quite regular in outline and evenly _convex_ (Fig.

243). Many mushrooms during the early stages of their development have

this form, which is variously changed by later growth. The convex

pileus usually becomes _plane_ or _expanded_ as it grows. If the

convexity is greater it is said to be _campanulate_ (Fig. 245), _conical

hemispherical_, etc., terms which need no explanation. The pileus is

_umbilicate_ when it has an abrupt, sharp depression at the center (Fig.

241), _infundibuliform_ when the margin is much higher than the center,

so that the cap resembles a funnel (Fig. 244), and _depressed_ when the

center is less, or irregularly, sunken. When the center of the pileus is

raised in the form of a boss or knob it is _umbonate_ (Fig. 242). The

umbo may have the form of a sharp elevation at the center, or it may be

rounded or obtuse, occupying a larger part of the disc. When it is

irregular or indistinct the pileus is said to be _gibbous_ (Fig. 246).

[Illustration: FIGURE 241. FIGURE 242. FIGURE 243.

FIGURE 242.--Lepiota procera, pileus convex, umbonate; annulus free,

movable; gills free.

FIGURE 243.--Agaricus campestris, pileus convex, gills free.]

=The gills.=--The _gills_ or _lamellæ_ are thin blades on the under

side of the pileus, radiating from the stem to the margin. When the

pileus is cut in halves the general outline of the gills may be

observed. In outline they may be broad, narrow, lanceolate, triangular,

etc. In respect to their ends they are _attenuate_ when gradually

narrowed to a sharp point, _acute_ when they end in a sharp angle, and

_obtuse_ when the ends are rounded. Again, the gills are _arcuate_ when

they arch from the stem to the edge of the pileus, and _ventricose_ when

they are bellied out vertically toward the earth.

[Illustration: FIGURE 244.

Clitocybe infundibuliformis, pileus infundibuliform, gills decurrent.]

[Illustration: FIGURE 245.

Mycena galericulata, pileus conic to campanulate, gills decurrent by a

tooth, stem fistulose.]

The terms given above are often used in descriptive works, but the most

important feature to be noted in the section of the plant is the

relation of the gills to the stem. This relation is represented by

several distinct types which are sometimes used to limit genera or

sub-genera, since the mode of attachment is usually constant in all

species of a group. The principal relations of the gills to the stem are

described as follows: _Adnate_ when they reach the stem and are set

squarely against it (Fig. 247); _decurrent_ when they run down the stem

(Fig. 244); _sinuate_ or _emarginate_ when they have a notch or vertical

curve at the posterior end (Fig. 246); and _free_ when they are rounded

off without reaching the stem (Fig. 243). In all cases when the lamellæ

reach the stem and are only attached by the upper angle they are said to

be _adnexed_. This term is often used in combination with others, as

_sinuate-adnexed_ (Fig. 248, small figure), or _ascending adnexed_ (Fig.

248, larger plant). Sometimes the lamellæ are adnate, adnexed, etc., and

have a slight decurrent process or tooth as in _Mycena galericulata_

(Fig. 245). In many plants the gills separate very readily from the stem

when the plants are handled. Sometimes merely the expansion of the

pileus tears them away, so that it is necessary to use great caution,

and often to examine plants in different stages of development to

determine the real condition of the lamellæ.

[Illustration: FIGURE 246. FIGURE 247. FIGURE 248.

FIGURE 246.--Tricholoma, gills sinuate, stipe solid.

FIGURE 247.--Panæolus papilionaceus, gills adnate.

FIGURE 248.--Left-hand small plant, Hygrophorus, gills sinuate, adnexed.

Right-hand plant Panæolus retirugis, gills ascending adnexed, veil

appendiculate.]

In certain genera the gills have special characteristics which may be

noted here. Usually the edge of the lamellæ is _acute_ or sharp like the

blade of a knife, but in _Cantharellus_ and _Trogia_ the edges are very

blunt or obtuse. In extreme forms the lamellæ are reduced to mere veins

or ridges. Again, the edge is generally _entire_, i. e., not noticeably

toothed, but in _Lentinus_ it is often toothed or cut in various ways.

In some other plants the edges are _serrulate_, _crenulate_, etc. In

_Schizophyllum alneum_, a small whitish plant very common on dead

sticks, the gills are split lengthwise along the edge with the halves

revolute, i. e., rolled back. In _Coprinus_ the gills and often a large

part of the pileus melt at maturity into a dark, inky fluid.

[Illustration: FIGURE 249.--Section of portion of gill of Marasmius

cohærens. _t_, trama of gill; _sh_, sub-hymenium; _h_, hymenium layer.

The long, dark cells are brown cystidia, termed spicules by some to

distinguish them from the colorless cystidia. The long cells bearing the

oval spores are the basidia.]

[Illustration: FIGURE 250.--Inocybe repanda (Bull.) Bres. (= Entoloma

repandum Bull.). _t_, trama of pileus; _sh_, sub-hymenium; _h_, the

hymenial layer; the long cells with a drop of moisture at the ends are

cystidia (sing. cystidium).]

=The hymenium.=--The term _hymenium_ is applied to the spore-bearing

tissue of many fungi. In the _Agaricaceæ_ the hymenium covers the entire

surface of the gills and usually the portion of the pileus between the

gills. It originates in the following manner: the threads forming the

trama of the gills grow out from the lower side of the pileus and

perpendicular to its under surface. As growth advances many branches of

the threads turn outward toward either surface of the gill and finally

terminate in club-shaped cells. These cells, therefore, lie side by

side, perpendicular to the surface, forming a pavement, as it were,

over the entire surface of the gills. Some of them put out four little

prongs, on each of which a spore is borne, while others simply remain as

sterile cells (Figs. 249, 250). The spore-bearing cells are _basidia_;

the others are called _paraphyses_. They resemble each other very much,

except that the basidia bear four _sterigmata_ and a spore on each. In a

few species the number of sterigmata is reduced to two and in some low

forms the number is variable. The layer just beneath the basidia is

usually more or less modified, being often composed of small cells

different from the rest of the trama. This is called the _sub-hymenial_

layer or _sub-hymenium_ (Fig. 250).

Other cells called _cystidia_ occur in the hymenia of various species

distributed through nearly all the genera of the agarics. Cystidia are

large, usually inflated, cells which project above the rest of the

hymenium (Fig. 250). They originate either like the basidia, from the

sub-hymenial cells (Fig. 250), or from special hyphæ deeper down in the

trama of the gill (Fig. 249). They are scattered over the entire surface

of the hymenium, but become more numerous on the edge of the lamellæ.

Their number is much smaller than that of the basidia, but in some

species where they are colored they may greatly change the appearance of

the gills. Cystidia often secrete moisture which collects in drops at

their tips, a phenomenon common to all free fungous cells.

=The stem.=--The stem is usually fixed to the center of the pileus, but

it may be _eccentric_, i. e., fixed to one side of the center, or

entirely lateral. When the stem is wanting the pileus is _sessile_. With

regard to its interior the stem is _solid_, when it is evenly fleshy

throughout (Fig. 246), or _hollow_ when the interior is occupied by a

cavity (Fig. 248). If the cavity is narrow and tubular the stem is

_fistulose_ (Fig. 245); and if the center is filled with a pithy

substance it is _stuffed_ (Fig. 243). These terms apply only to the

natural condition of the stem, and not the condition brought about by

larvæ, which eat out the interior of the stem, causing it to be hollow

or fistulose.

The terms applicable to the consistency of the stem are difficult to

define. In general, stems may be either _fleshy_ or _cartilaginous_. The

meaning of these terms can best be learned by careful study of specimens

of each, but a few general characters can be given here. Fleshy, fibrous

stems occur in the genera _Clitocybe_ and _Tricholoma_, among the

white-spored forms. Their consistency is like that of the pileus,

namely, made up of fleshy, fibrous tissue. They are usually stout,

compared with the size of the plant, and when bent or broken they seem

to be more or less spongy or tough, fibrous, so that they do not snap

readily. Cartilaginous stems have a consistency resembling that of

cartilage. Their texture is always different from that of the pileus,

which is fleshy or membranous. In general such stems are rather slender,

in many genera rather thin, but firm. When bent sufficiently they either

snap suddenly, or break like a green straw, without separating. In

regard to their external appearance some resemble fibrous stems, while

others are smooth and polished as in _Mycena_ and _Omphalia_.

=The veil.=--In the young stages of development the margin of the pileus

lies in close contact with the stipe, the line of separation being

indicated by a kind of furrow which runs around the young button

mushroom. In many genera, as _Collybia_, _Mycena_, _Omphalia_, etc., the

pileus simply expands without having its margin ever united to the stipe

by any special structure, but in other forms, which include by far the

greater number of genera of the _Agaricaceæ_ and some _Boleti_, the

interval between the stem and pileus is bridged over by threads growing

from the margin of the pileus and from the outer layers of the stem.

These threads interlace to form a delicate membrane, known as the

_veil_, which closes the gap between the stem and pileus and covers over

the young hymenium.

The veil remains firm for a time, but it is finally torn by the

expanding pileus, and its remnants persist on the cap and stem in the

form of various appendages, whose character depends on the character of

the veil. In _Cortinarius_ the veil is made up of delicate threads

extending radially from the stem to the margin of the cap without

forming a true membrane. From its resemblance to a spider's web such a

veil is said to be _arachnoid_. At maturity mere traces of it can be

found on the stem. In many genera the veil consists of a delicate

membrane which tears away from the stem and hangs in flakes to the

margin of the pileus. In these cases the veil is _appendiculate_ (Fig.

248). Frequently it is so delicate that no trace of it remains on the

mature plant. Where the veil is well developed it usually remains on the

stem as a _ring_ or _annulus_ which becomes free and movable in species

of _Lepiota_ (Fig. 242) and _Coprinus_, or forms a hanging annular

curtain in _Amanita_, or a thick, felty ring in _Agaricus_, etc. In some

plants (species of _Lepiota_) the annulus is continuous with the outer

cortex of the stem, which then appears as if it were partially enclosed

in a sheath, with the annulus forming a fringe on the upper end of the

sheath, from which the apex of the stem projects.

No reference is here made to the _volva_, which encloses the entire

plant, and which is described in connection with the genera in which it

occurs.

The few typical characters described here will help the student to

become familiar with terms applied to them. In nature, however, typical

cases rarely exist, and it is often necessary to draw distinction

between differences so slight that it is almost impossible to describe

them. Only by patient study and a thorough acquaintance with the

characters of each genus can one hope to become familiar with the many

mushrooms growing in our woods and fields.

Veil, a layer of threads extending from the margin of the cap to the

stem (partial veil or marginal veil). A universal veil envelops

the entire plant.

Veins, elevated lines or folds running over the surface of the lamellæ

in some species, and often connected so as to form reticulations.

Ventricose, enlarged or broadened at the middle, bellied.

Vesiculose, full of small rounded vesicles, as the trama of the pileus

of a Russula.

Volva, a wrapper or envelope, which in the young stage completely

surrounds the plant, same as universal veil. At maturity of the

plant it may be left in the form of a cup at the base of the stem,

or broken up into fragments and distributed over the cap and base

of the stem.
