LEUCOSPORI. 137 



286. A. setites Fr. Pileus 12 mm. (X in.) broad, fuscous-grey, Mycena. 

 becoming pale, membranaceous, campanulate then convex, with a 

 broad, obtuse, prominent umbo, sulcate to the umbo, smooth. Stem 



5 cent. (2 in.) long, fistulose, but often compressed, and then the 

 tube disappears, unequal, fragile, smooth, shining, becoming 

 whitish-fuscous. Gills adnate, somewhat uncinate, a little arcuate, 

 thin, at first cohering in the form of a collar, beautifully reticu- 

 lated with veins, somewhat distant, white, grey at the sides. 



Odour bitterish or obsolete ; growing in troops. The pileus is sometimes 

 rufescent as in the figure of Schaeffer ; when dry the very margin becomes black, 

 not the whole striate part as in A. peltatus.

287. A. stanneus Fr. Pileus 4 cent. (ij in.) broad, hygro- 

 phanous, grey when moist, when dry tin-colour, silky glistening, 

 smooth however, membranaceous, campanulate then flattened, 

 fragile, often rimose, striate, smooth. Stem 5-7.5 cent. (2-3 in.) 

 long, 2 mm. (i lin.) thick, but compressed to 4 mm. (2 lin.) in 

 breadth, narrowly fistulose, slightly rigid, even, shining, smooth, 

 becoming pale, not very fragile. Gills adnate, with a small decur- 

 rent tooth, scarcely crowded, connected by veins, whitish grey. 



Inodorous. Scattered or loosely gregarious. It differs abundantly from A. 

 metatus in its rigidity, in its glistening pileus when dry, and in its whole 

 nature; it may rather be compared with A. collariatus among Filipedes.

288. A. vitreus Fr. Pileus 2.5 cent, (i in.) broad, opaque, 

 fuscous then livid or bluish-grey, wholly membranaceous ; very 

 thin, campanulate, obtuse, wholly lineato-striate, smooth, dry, 

 margin entire, naked. Stem 5-10 cent. (2-4 in.) long, i m. (% 

 lin.) thick, remarkably fistulose, equal, smooth, glistening', striate 

 under a /ens, fibrillose at the base. Gills adnate, linear, distinct, 

 thin, somewhat distant, whitish, of the same colour at the edge. 



It has no umbo or slightly fleshy disc. The whole plant -very fragile, juice- 

 less, inodorous. Elegant, growing in troops. Among mosses the stem is ex- 

 tended at the base and spuriously rooted. This and A. tennis differ from the 

 rest in the substance being much thinner.
