Clitocybe nebularis. 
A cespitose form of the species was observed in the Catskill moun- 
tains. Also a form in which the whole plant is white. This is the 
common form in these mountains. It has the same shape as the 
typical form, from which it differs only in color. 
Clitocybe laccata, Scop. var. amethystina. 
Specimens of this beautiful variety were found at Menands and at 
Karner in August. Two forms occur, in both of which the pileus is 
umbilicate and dark violaceous when moist, canescent or greyish 
when dry ; in one the pileus is abomt one inch broad, convex and 
regular ; in the other it is two to two and a half inches broad, and has 
the margin reflexed and often much lobed and wavy. In this form 
the lamelle are broad, distant and often ruptured transversely. They 
are also more highly colored than in the typical form. The ordinary 
form has been found growing in circles in grassy places. 
Collybia lentinoides, Px. 
A description of this species was published in the Thirty-second 
Report. Two varieties have been observed the past season. 
Variety rujipes. Stem even, colored reddish-alutaceous lke the 
pileus. This variety closely resembles ordinary forms of Collybia dry- 
ophila in color, and but for the serrated edge of the lamelle it might 
easily be taken for that species. Albany Rural cemetery. June. 
Variety flaviceps. Pileus buff-yellow and striatulate on the margin 
when moist, pale buff when dry ; stems cxspitose, hollow, whitish. 
In all the forms the essential characters of the species are the glab- 
rous, hygrophanous pileus, the lamelle with serrated edge and the . 
stuffed or hollow stem. 
Collybia rubescentifolia, Pk. 
In the Thirty-ninth Report this species was referred to Tricholoma, 
but subsequent observations indicate that it is a Collybia. The pileus 
is pretty constantly umbilicate and is hygrophanous, being dingy- 
yellow or smoky-yellow when moist and pale-yellow or buff when dry. 
The change in the color of the lamelle in the dried plant is a marked 
and constant character, and is suggestive of the specific name. The 
species is closely allied to C. luteodlivacea B. & C., but no hygrophanous 
character is attributed to that species nor any change in the color of 
the lamellz. Besides, its stem is described as scurfy.
