Il6 AGARICUS. 



238. A. inoleiis Fr. Pileus 2.5-5 cent - ( l ~ 2 i n -) broad, hygro- 

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

 when dry, but opaque, slightly fieshy, campanulato-convex then 

 plane, for the most part obtusely and broadly umbonate, 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/4 lin.) thick and broader in becoming compressed, rigid, 

 delicately fistulose, at length softer and hollow, equal, undulated 

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

 the base and white squamulose 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 odour is -weak, and often obsolete. 



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

239. A. plexipes Fr. Pileus 2.5-5 cent - ( l ~ 2 m -) broad, at 

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

 fleshy- membranaceous, campanulate (not flattened), umbonate, 

 somewhat wrinkled, slightly striate. Stem 7.5 cent. (3 in.) long, 

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

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

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

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

 attenuated behind, free, ventricose, somewhat crowded, white then 

 becoming glaucous. 



Most distinct ; quite inodorous, tough, firm, very like Mycen<z rigipedes, but 

 not allied to these. By analogy it is nearest to A. ranc^d^^s. 



In woods. Uncommon. Oct.

 fiesJiy, firm, piano-depressed at the disc, convex towards the 



margin, orbicular, very even, smooth, viscid when very long 

 wetted. Stem curt, scarcely 2.5 cent, (i in.) long, 2-4 mm. (1-2
