CLASSIFICATION OF AGARICS 



scales, even on margin when moist. STEM fibrillose-fioccuh 

 glabrescent. SPORES 7-8s 1-5 micr., Blightl} unequally ellipticaL 

 CYSTIDIA on sides of ^ills scattered to somewhal aumerouM, 

 ventricose-sublanceolate but obtuse, about 50 micr. long. HTKHILK 

 CELLS pyriform inflated, numerous <>n edge of uills.

This may be Psilocybi polycephala (Paul.) (see N. ¥. State 

 .Mus. Bull. L57, p. 98, PL 127, Fig. I '.». L912), which it approaches 

 very closely. Ii is aot Psilocybi spadicea and does not appear t" 

 be closely related to it. Ii is close to //. hydrophilum with which 

 it agrees except in the points mentioned. Cooke's figure (111., PI. 

 L157) which is doubtfully referred to //. instratwn Brits, is per 

 haps the same; ai least ii is oot Britzelinayr's planl which lias 

 rounded-triangular spores.

 N. V. State Mus. Rep. 25, IS?::. 



PILEUS 1--'! cm. broad, fragile, obtuse, ovate at first, then cam- 

 panulate to plane, pale watery-brown and even when moist, pallid 

 ochraceous when dry. hygrophanous, in age assuming a livid-gray or 

 watery-soaked appearance when remoistened, at firsl sprinkled with 

 white Hecks or flocculent scales, glabrescent and Bubatomate. 

 FLESH soft, thin. GILLS adnate-seceding, narrow, sublinear or 

 subventricose, close, white at first, slowly becoming pinkish to 

 fuscous-purplish, edge white linihriale. STEW 3-7 cm. thick. 

 fragilej subequal, undulate, white. silky-fibrilloHe, pruinose-fl 

 at apex, hollow, even, subbulbillate at base with radiating mycelium. 



VEIL delicate. Ilocculose liliri 1 lose, while. e\ a lie-cent . SI'm|; - 



6-7x3-4.5 micr., elliptical-oblong, smooth, obtuse, purplish-brown in 



mass, pale under microscope. CYSTIDIA none <>n si,|rs. of u'dN. 



STERILE CELLS on edge, large, undulate-cylindrical, abundant, 

 broadly obtuse, 40-50x9-11 micr.

Although this species was rejected by Peck in his monograph 

 the New York species (Bull. 150, 1911) it is revived Ik 

 supply a name for our species. The cap is characterised b 

 striate margin, and by its peculiar change in color when i
