LEUCOSPORI. 139 



aceous, conico-campanulate, but scarcely umbonate, slightly pel- Mycenz 

 lucid-striate to the middle, also pruinate when in full vigour, but 

 the pruina easily separates. Stem about 7.5 cent. (3 in.) long, 

 thinly fistulose, filiform, equal, /far?/?, wholly villous-pnlverulent, 

 livid, but the very long tortuous root is almost smooth. Gills free, 

 or only reaching the stem, linear, crowded, narrow, grey, the 

 edge paler. 



Gregarious, inodorous, very much tougher than A. filopes. The floccoso- 

 pruinose covering seems a species of veil.

292. A. debilis Fr. Pileus 4-6 mm. (2-3 lin.) broad, whitish 

 livid, somewhat flesh -colour, &c., becoming fuscous when dry, 

 membranaceous, very thin, campanulate then convex, obtuse, 

 striate when moist, when dry even, but withering and corrugated. 

 Stem 5-10 cent. (2-4 in.) long, slightly fistulose, capillary-filiform, 

 weak and lax, of the same colour as the pileus, fibrillose at the 

 base. Gills broadly adnate, rather broad, distinct, somewhat 

 distant, whitish, edge of the same colour. 



Gregarious ; soon withering in fine weather. In this natural habit it departs 

 very widely from all the others in this group. It is in reality intruded among 

 species which are not allied, on account of its filiform, juiceless, but flaccid 

 rather than flexile stem. It is readily distinguished from A. sanguinolentus , 

 which is very like it, by its gills being' of the same colour at the edge. The 

 umbo, if present, is obtuse.

293. A. vitilis Fr. Pileus 6-8 mm. (3-4 lin.) broad, fuscous 

 or livid, becoming pale or whitish, membranaceous, conical then 

 campanulate, papillate, not wrinkled, but striate to the middle, 

 dry, smooth. Stem 7.5-15 cent. (3-6 in.) long, thinly fistulose, 

 filiform, rooted, tense and straight, rigid but tough, easily flexile, 

 even, smooth, juiceless, shining, livid. Gills attenuato-adnate, 

 and without a decurrent tooth, ascending, linear, thin, distinct, 

 whitish or grey. 



The pileus is deeply striate when moist, becoming even when dry. The 

 slightly fleshy papilla often vanishing. The gills sometimes slightly sinuate, 

 or, in a variation in which the pileus is fuscous, dark cinereous with a whitish
