ri6 AGARICUS. 



Coiiybia. 238. A. inolens Fn— Pileus 2.5-5 cent. (1-2 in.) broad, hygro- 



phanous, livid when moist, becoming pale-tan and slightly silky 

 when dry, but opaque, sliglitly fleshy, campanulato-convex then 

 plane, for the most part obtusely and broadly umbojiate, very 

 smooth, margin at first inflexed, then expanded, striate, here and 

 there undulated. Stem 5-7.5 cent. (2-3 in.) and more long, 2-3 

 mm. (i-i/^ lin.) thick and broader in becoming compressed, rigid, 

 delicately fistulose, at length softer and holloiu^ equal, inidulated 

 on the surface, livid, becoming pale when dry, white strigose at 

 the base aiid white sqiiaimilose at the apex. Gills adfixed, separat- 

 ing, somewhat free, 2-4 mm. (1-2 lin.) broad, linear or a little 

 ventricose, somewhat imbricated, whitish-grey. 



The pileus is not so cartilaginous as in A. rancidus and A. coracinus. 

 Manifestly related to these, but the odoia- is weak, and often obsolete. 



In woods, chiefly pine. Uncommon. Sept.-Nov.

239. A. plexipes Fr.— Pileus 2.5-5 cent. (1-2 in.) broad, at 

 first blackish, whitish at the margin, then fuliginous- livid, 

 fleshy- membranaceous, ctnnpa7nilate (not flattened), umbo7iate, 

 soniewJiat iuri7ikled, slightly striate. Stem 7.5 cent. (3 in.) long, 

 2-4 mm. (1-2 lin.) thick, fistulose, equal, wholly cartilaginous, 

 but the surface binder a lens is silky fibrous with the closely ad- 

 pressed entwined fibrils, and slightly striate, livid, shortly a?td 

 bliaitly rooted at the base and not strigose. Gills very much 

 attenuated behind, y>'<?^, ventricose, soinewhat crowded, white then 

 becoming glaucous. 



Most distinct ; quite inodorotis, tough, firm, very like MycencB rigipedes, but 

 not allied to these. By analogy it is nearest to A. rancidus. 



In woods. Uncommon. Oct.
