334 AGARICUS. 



Psathyra. 1 1. OBTUSATi. Pileus campanulato-convex, &*c. 



748. A. spadiceo-griseus Schaeff. Pileus 5 cent. (2 in.) and 

 more broad, date-brown when moist, whitish-grey when dry, very 

 hygrophanous, somewhat membranaceous, very fragile, campan- 

 ulate then convex, and at length flattened, obtuse, smooth, even, 

 but from its moist substance pelhtcid- striate to the middle. Stem 

 7.5 cent. (3 in.) long, 4 mm. (2 lin.) thick, fistulose, equal, whit- 

 ish, shining, striate at the apex, sometimes pulverulent. Gills 

 attenuated behind, hence adnexed only, crowded, narrow, at first 

 ascending, then plane, umber-fuscous. 



Solitary or gregarious ; sometimes many stems are joined, but not growing 

 together at the base. Watery, fragile. Veil none. 



On wood. Frequent. Oct.-Nov.

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

 date-brown-fuscous or umber-ftiscous, 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, 

 2-4 mm. (1-2 lin.) thick, fragile, fistulose, round, equal, fibrilloso- 

 silky, not pulverulent, whitish, even at the apex. Veil none. Gills 

 adnate, broad, distinct, somewhat distant, cinereous-fuscous, then 

 umber. 



Thin, rigid-fragile ; single or csespitose. 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. 



On the ground and on wood. Rare. Aug. 



Name obtusus, blunt. Obtuse. Fr. Monogr. i. p. 441. Hym. Eur. p.

 wavy teeth.
