Series 2. =Carpoasci.=

The Carpoasci are Ascomycetes, whose asci are enclosed in fruit-bodies,

_i.e. ascocarps_. The accessory means of reproduction are free

conidiophores (Fig. 109), conidial-layers (Fig. 122), conidiocarps

(Fig. 120 _D_, _E_, etc.), chlamydospores and oidia.

For the different methods of distributing the ascospores, see p. 92.

Of the six families of the Carpoasci, the first three--_Gymnoascales_,

_Perisporiales_, and _Pyrenomycetes_--are ANGIOCARPIC (that is,

the ascocarp remains closed throughout its existence, and does not

dehisce when ripe); the fourth and fifth families (_Hysteriales_ and

_Discomycetes_), on the other hand, are HEMIANGIOCARPIC (the ascocarp,

here also called an _apothecium_, is closed in the early stages,

but opens at the commencement of ripening and exposes a hymenium of

crowded asci); the family of _Helvellales_ has probably GYMNOCARPIC (or

hemiangiocarpic) fruit-bodies.
