Pileus 1.6-2.4 mm broad; stem 3-5 cm long, 2 mm thick. 



Ground and decaying- wood under pine trees, Albany co, June 

 and July. Rare. 



In wet weather the pileus has a moist brownish appearance, but 

 its moisture escapes quickly. The spore print on white paper is 

 almost black, but the spores are much smaller than those of P s a - 

 thyrella atomata Fr. It also approaches Hypholoma 

 i n c e r t u m Pk. in general appearance but differs in the color 

 and character of the lamellae. 



Psilocybe conissans Pk.

 N. Y. State Mus. Bui. 122, p.131 

 N. Y. State Mus. Rep't 41, p. 64 ; 42, p.45 as Clitopilus conissans Pk. 

 Pileus fleshy but thin, broadly convex becoming nearly plane, 

 glabrous, hygrophanous, pale chestnut or ferruginous and striatulate 

 on the margin when moist, pale alutaceous or pale buff' and some- 

 times slightly rugose when dry, flesh whitish ; lamellae thin, close, 

 rounded behind, adnexed or rarely adnate, bay verging to dark 

 purple or liver color; stem equal, rather slender, firm, glabrous, 

 hollow, curved or flexuous, white, veil none ; spores red or vinaceous, 



8-10 X 4-5 [X. 



Pileus 2.5-5 cm broad ; stem 2.5-5 cm long, 2-4 mm thick. 



Cespitose. On or about the base of deciduous trees. Ulster, 

 Essex and Saratoga counties. September and October. Not 

 common. 



Remarkable for and easily distinguished from all other species 

 of this genus by the color of the spores. By reason of their color 

 the species was formerly referred to the genus Clitopilus. But their 

 color is darker than pink and paler than purplish brown. Its other 

 characters indicate Psilocybe as its proper genus. 



Psilocybe squalidella Pk. 



SQUALID PSILOCYBE 

 N. Y. State Mus. Rep't 29, p.40 as Agaric us (Hypholoma) 



squalidellus Pk. 

 Pileus thin, convex, subconic or subcampanulate, expanded when 

 old, glabrous, hygrophanous, dark ochraceous and striatulate on the 

 margin when moist, pale ochraceous or yellow when dry, spore 

 stained and squalid when old ; lamellae broad, subdistant, rounded 

 behind, adnexed, whitish becoming purplish brown with a whitish
