 ish, shini7ig, striate at the apex, sometimes pidvenile?tt. Gills 

 attemiated behind, hence adnexed only, crowded., narrow, a.t first 

 ascending, then plane, umber-fuscous.

749. A. obtusatus Fr. — Pileus 2.5 cent, (i in.) and more broad, 

 date-brown-fuscous or umber-fiiscotts, paler at the margin, some- 

 what membranaceous, conical when young, then convex, at length 



flattened, obtuse, even at the disc, striate at the margin ; flesh 

 scarcely any, of the same colour. Stem 5-7-5 cent. (2-3 in.) long,

 silky, not pulverulent, whitish, eve?t at the apex. Veil none. Gills 

 adftate, broad, distinct, somewhat distant, cinereoiis-fiiscous., then 

 umber. 



Thin, rigid-fragile ; single or casspitose. In the colours and in the absence 

 of a veil it approaches near to A. spadiceus, but is easily distinguished by its 

 stature, by the nature of the stem, and by the gills never being flesh-colour.
