REPORT OF THE STATE BOTANIST I9II 99 



nearly straight, rigid, fragile, hollow, glabrous, pruinose at the top, 

 pallid or rufescent; spores brown, ovoid or unequally ellipsoid, 

 obscurely and bluntly apiculate at one end, 12-16 x 8-10 p (10-12 x 

 6-7 /x in Sylloge). 



Pileus 1.2-2.4 cm broad; stem 5-7 cm long, 1.5-2 mm thick. 



Gregarious. Lawns and rich soil in grassy places. Albany co. 

 May and June. Edible. 



The spores in our plant are a little larger than the dimensions 

 attributed to those of the European plant, but we have not con- 

 sidered this difference of sufficient weight to justify the separation 

 of our plant as a distinct species. Sometimes the moist pileus shows 

 striatulations on the margin but this character is not constant. 

 The moisture escapes from the center of the pileus sooner than from 

 the margin. This is according to the usual habit of hygrophanous 

 species.

phyllogenus Pk. 



Pileus thin, firm, convex, sometimes slightly umbonate, hygro- 

 phanous, reddish brown when moist, alutaceous when dry; lamellae 

 plane, broad, close, brown, white on the margin ; stem equal, fibrillose, 

 stuffed or hollow, brownish, expanding at the base into a thin flat 

 disk which adheres closely to the leaf on which it grows ; spores pa'e 

 brown, subglobose, 6-8 n in diameter. 



Pileus 4-8 mm broad; stem 1.5-2.5 cm long, 1-2 mm thick. 



Fallen leaves in woods. Otsego co. July. 



One of our smallest species. P>ecause of the absence of a veil it 

 belongs to the genus Psilocybe rather than to Hypholoma to which 

 it was originally referred. The closely related H y p h o 1 o m a 

 modestum Pk. is probably only a form of this species, from 

 which it differs slightly in its larger size, its grayish young lamellae 

 and its inhabiting sticks and twigs instead of leaves. It may be 

 designated Psilocybe phyllogena m o d e s t a Pk. 



Psilocybe castanella Pk.
