The =pileus= is fleshy, thin, convex to nearly plane, or even with the margin upturned in old plants, and the center sometimes umbonate. It is smooth, viscid when moist, and often with wrinkles on the surface which extend radially. The color varies from nearly white in some small specimens to grayish, grayish brown or umber. The flesh is white. The =gills= are white, broad, rather distant, adnexed, i. e., joined to the stem by the upper angle. The =spores= are elliptical and about 15 × 10 µ. The =stem= is the same color as the pileus though paler, and usually white above, tapers gradually above, is often striate or grooved, or sometimes only mealy. The long tapering "root" is often attached to some underground dead root. Fig. 94 is from plants (No. 5641, C. U. herbarium) collected at Ithaca, August, 1900.

Copyright.] =Collybia velutipes= Curt. =Edible.=--This is very common in woods or groves during the autumn, on dead limbs or trunks, or from dead places in living ones. The plants are very viscid, and the stem, except in young plants, is velvety hairy with dark hairs. Figure 95 is from plants (No. 5430, C. U. herbarium) collected at Ithaca, October, 1900. =Collybia longipes= Bull., is a closely related plant. It is much larger, has a velvety, to hairy, stem, and a much longer root-like process to the stem. It has been sometimes considered to be merely a variety of _C. radicata_, and may be only a large form of that species. I have found a few specimens in the Adirondack mountains, and one in the Blue Ridge mountains, which seem to belong to this species. =Collybia platyphylla= Fr. =Edible.=--This is a much larger and stouter plant than _Collybia radicata_, though it is not so tall as the larger specimens of that species. It occurs on rotten logs or on the ground about rotten logs and stumps in the woods from June to September. It is 8--12 cm. high, the cap 10--15 cm. broad, and the stem about 2 cm. in thickness. The =pileus= is convex becoming expanded, plane, and even the margin upturned in age. It is whitish, varying to grayish brown or dark brown, the center sometimes darker than the margin, as is usual in many plants. The surface of the pileus is often marked in radiating streaks by fine dark hairs. The =gills= are white, very broad, adnexed, and usually deeply and broadly notched next the stem. In age they are more or less broken and cracked. The =spores= are white, elliptical, 7--10 × 6--7 µ.
