Scattered or somewhat gregarious, in woods, mossy swamps and 

 open places. July to October. Common. Edible. 



This is a fine large pholiota easily recognized by its peculiar 

 wrinkled pileus and the white pruinosity or floccose covering of the 

 centcK of the pileus. Sometimes, however, specimens may occur in 

 which neither the wrinkles nor tiie flocci are present. Occasionally 

 there is the semblance of a volva at the base of the stem. The 

 annulus is usually well developed, white and persistent. 



Pholiota rugosa Pk. 

 RUGOSE PHOLIOTA 



Pileus thin, broadly conic or campanulate becoming expanded and 

 often umbonate, hygrophanous, yellowish red or ferruginous and 

 striatulate on the margin when moist, pale yellow or buff and com- 

 monly rugose when dry; lamellae close, adnexed, minutely denti- 

 culate on the edge, yellowish white becoming ferruginous or 

 brownish ferruginous, the interspaces venose ; stem equal or slightly 

 thickened toward the base, straight or flexuous, hollow, fibrillose or 

 squamulose below the annulus, pruinose or mealy above, pallid, the 

 annulus membranous, with radiating ridges or striations on the upper 

 surface, white ; spores .0004-.0005 of an inch long, .00024-.00028 

 broad. 



Pileus 6-12 lines broad; stem 1-2 inches long, 1-2 lines thick. 



Ground and among decaying chips. Adirondack region. Sep- 

 tember. The species is closely related to Pholiota togularis 

 (Bull.) Fr. from which it is separated by the hygrophanous pileus, 

 the adnexed lamellae and the peculiar striations of the annulus. 



Pholiota maris (Fr.) Pk. 

 THREAD STEM PHOLFOTA 



Pileus submembranous, campanulate becoming broadly convex or 

 nearly plane, obtuse, even, but slightly striate on the margin, 

 ochraceous ; lamellae thin, close, adnate, ventricose, yellow becoming 

 pale ferruginous; stem filiform, flexuous, glabrous, pallid, the 

 annulus well developed, distant, white ; spores .0003 of an inch long, 

 .0002 broad. 



Pileus 4-6 lines broad ; stem 1-2 inches long, scarcely half a line 

 thick.
