w2 THE AGARICACEAE OF MICHIGAN 



485. Inocybe albodisca Pk. 

 N. V. Stale Mus. Kep. 51, 1898. 



PILEUS L.5-3.5 cm. broad, corneal at first, soon cainpanulate- 

 umbonate or expanded, umbo lubricus-glabrous, obtuse and whitish, 

 elsewhere silky, at first pale lilac-flesh color, at length grayish-drab 

 and riii lose; FLESH whitish, not changing color. GILLS rather 

 n anew, close, narrowly adnate, whitish at first, then subferrugi- 

 n. .us, edge minutely white-flocculose. STEM 3-5 cm. long, 3-5 mm. 

 thick, equal, subbulbillate to somewhat marginate-bulbous, solid, 

 glabrous or upper part pruinate, at first tinged by color of pileus, 

 fading, even. SPORES sinuate-angular, subrectangular to sub- 

 globose in outline, shape variable, 7-8x5-6 micr., nucleate. CYS- 

 TIDIA very abundant on sides and edge of gills, crystallate at 

 apex, lusoid-ventricose, about 50x15 micr. Basidia 33x9 micr., 

 I -pored. ODOR slight, subnauseous. 



Gregarious-scattered. On the ground, clay soil of hemlock and 

 beech woods. New Richmond. September. Infrequent. 



Known by its glabrous, whitish, obtuse umbo, submarginate 

 bull), and the- peculiar shade of pale lilac-incarnate color when 

 young. This color disappears in older specimens where the cap 

 takes on a grayish shade and becomes rimose. The spores distin- 

 guish it sharply from /. huiatodisca, and the smaller size of the 

 plan i and spores separate it from I. fibrosa. It is closely related to 

 /. innbratica Bres. and /. fallax Pk.

 brown or rufous-brown, very rimose, fibrillose-scaly ; FLESH pallid, 

 rather thin. GILLS narrowly aduate, emarginate, ventricose, close, 

 al length olivaceous-cinnamon or grayish-brown. STEM 4-6 cm.
