Clitocybe nebularis. 

 A caespitose form of the si^ecies 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 

 tyi:)ical 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 grejash 

 when dry ; in one the pileus is about one inch broad, convex and 

 regular ; in the other it is two to two and a half inches broad, and has 

 tliC margin reflexed and often much lobed and wavy. In this form 

 the lamellte 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, Pl\ 



A description of this species was published in the Thii-ty-second 

 Report. Two varieties have been observed the past season. 



Variety rufipes. Stem even, colored reddish-alutaceous like the 

 pileus. This variety closely resembles ortlinary forms of Collybia dry- 

 vphila. in color, and but for the serrated edge of the lamellte it might 

 easily be taken for that species. Albany Eural cemetery. June. 



\ax\eij Jlavicep!:. Pileus buff-yellow and striatulate on the margin 

 when moist, pale buff when diy ; stems c»spitose, hollow, whitish. 



In all the forms the essential characters of the species are the glab- 

 rous, hygrophanous pileus, the lamelhe 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 pilous 

 is pretty constantly umbilicate and is hygrophanous, being dingy- 

 yellow or smoky-yellow when moist and pale-yellow or butT when dry. 

 The change in the color of the lamelhe in the di-ied plant is a marked 

 and constant character, and is suggestive of the specific name. The 

 species is closely allied to C. UUeoOliracea B. Sc C, but no hygrophanous 

 character is attributed to that species nor any change in the color of 

 the lamellfe. Besides, its stem is described as scurfy.
