North American species of Mycena.

as M. amabilissima and, in fact, the two look almost alike. From
Peck's comments and material it appears that he had collected the
species in quantity and knew it well. My collections in New York
and Ontario have been confined, unfortunately, to only a few scattered
fruiting bodies. From limited observations on fresh specimens, and
from a study of the type, I believe that the fungus is more closely
related to M1. rosella than to any other Mycena. The consistency
and color of the carpophores and the two kinds of cheilocystidia
strikingly emphasize this relationship. The greatest difference appears to be that in M. subincarnata the gill edges are not differently
colored. This point was checked carefully in the field against fresh
material of M. rosella. In my collections the colors of M. subincarnata
were even more delicate than those of M. rosella, with the result that
the former appeared rather waxy and Hygrophorus-like.
The drawings were made from collection 700, Warrensburg, New
York. The microscopic details of the type are those given in the
description above, but my drawings of its spores and cystidia were not
made with the camera lucida. Kuihner, after a study of some specimens which I sent him, reported the spores as nonamyloid, an observation I have not been able to confirm.

Pileus 1-3 cm. broad, conic to obtusely campanulate, becoming
either plane or umbonate, the margin at times appressed against the
stipe in young specimens and sometimes connivent with it, frequently
with a wavy uplifted margin in age, translucent-striate when moist,
becoming slightly sulcate when faded, glabrous, moist, and hygrophanous, "Pompeian red" on the disc and "light jasper red" to "coral
pink" toward the margin, sometimes the disc not darker, fading to
"flesh color"; flesh thin, incarnate, brittle, odor and taste not distinctive; lamellae ascending-adnate, becoming horizontal and slightly
toothed, close, 23-28 reach the stipe, moderately broad (3 mm. i),
edges even and whitish or tinged "flesh pink" to "coral pink" when
the faces are similarly tinted; stipe 4-7 cm. long, 1-3.5 mm. thick,
