[11] Coulter's record for Gibson County by Schneck is regarded as an
error because Schneck himself does not report it, and there was no
specimen in the Schneck herbarium.
[12] Deam's record in Rept. Ind. St. Board Forestry 1911:124:1912 was a
manuscript error.

[15] Heimlich in Proc. Ind. Acad. Sci. 1917:437:439:1918 credits most of
my records jointly with Prof. G. N. Hoffer. This is an error. On my
invitation Prof. Hoffer accompanied me nine days in the field doing
mycological work. While he gave me valuable assistance in collecting
during these days, his assistance and responsibility stopped there
and he never asked or expected to be considered joint author. Again
on our trip we collected only in Daviess, Gibson, Fountain, Knox,
Lawrence, Martin, Pike and Sullivan Counties.

[49] =Morus alba= Linnæus. White Mulberry. A small crooked tree; leaves
ovate, sometimes lobed, blades 6-13 cm. long, cordate at the base,
acute at apex, at maturity glabrous above and glabrous beneath or
with some hairs on the veins and in the axils of the veins; fruit
subglobose or oblong, 1-2 cm. long, white to pinkish. This is an
introduced tree and has been reported as an escape in many parts
of the State, especially by the older botanists. =Morus alba=
variety =tatarica= Loudon, the Russian mulberry, has been reported
as an escape. The writer has seen single specimens as an escape in
woods in Cass and Marshall Counties. It can be distinguished by
practically all of the leaves being more or less lobed and the
reddish fruit. This form was introduced into the United States in
great numbers about fifty years ago by the Mennonites. It was
especially recommended by nurserymen for fence posts and it has been
planted to some extent in Indiana, but it cannot be recommended. It
grows too slowly and is too crooked to compensate for any lasting
qualities the wood may have. =Morus nigra= has been reported from
Indiana by Phinney, Brown and McCaslin as a forest tree. Since this
is an introduced tree, and is not supposed to be hardy in our area,
their reports should be transferred to some other species.
