DERMINI. 255 



I. Indusiati (indusium, a. garment). Furnished with a cortina from the Hebeloma. 

 manifest veil, by which the pileus is often superficially silky round the margin. 



II. Denudati (denudo, to lay bare). Pileus smooth, at the first with no 

 cortina. 



III. Pusillus (diminutive from pusus, a little boy). Pileus scarcely an inch 

 broad. Stature that of the Naucoriae.

 manifest veil, &^c. 



567. A. mussivus Fr. Pileus 5-10 cent. (2-4 in.) broad, either 

 of one colour, yellow, or darker at the disc which is like a smooth 

 sugar-cake, fleshy, compact, firm, convex then plane, unequal, 

 very obtuse, viscid, at first smooth and even, then commonly 

 repand and broken up into squamules ; margin inflexed, even, at 

 length repand ; flesh becoming yellow. Stem 10 cent. (4 in.) 

 long, commonly 2.5 cent, (i in.) thick, very fleshy, sometimes 

 stuffed, sometimes hollow at the apex, equal or ventricose, wholly 

 fibrillose and pruinate at the apex, light yellow. Veil fibrillose, 

 very fugacious. Gills emarginate, somewhat crowded, 6 mm. 

 (3 lin.) broad, arid (not distilling drops) at flrst light yellow, then 

 together with the spores somewhat ferruginous. 



Odour weak, not unpleasant. Very distinct ; it departs widely from all the 

 following species in its habit and bright colours. The habit is that of a 

 Flammula or Cortinarius, but the gills are emarginate and not pulverulent ; 

 from the repand pileus, from the stem being pruinose at the apex, and from 

 other marks it is to be referred to Hebelomata.

568. A. fastibilis Fr. Pileus 5 cent. (2 in.) and more broad, 

 pale yellowish, tan or becoming pale, compactly fleshy, convexo- 

 plane, obtuse, somewhat repand, even, smooth, the involute mar- 

 gin pubescent. Stem 5-7.5 cent. (2-3 in.) long, 12 mm. (}4 in.) 

 thick, solid, wholly fleshy-fibrous, stout, somewhat bulbous, often 

 twisted, everywhere white-silky and fibrillose, white, but varying 

 pallid, white-scaly upwards. Cortina remarkable, white, occa- 

 sionally in the form of a ring. Gills remarkably emarginate, 

 somewhat distant, rather broad, at first becoming pale-white, 

 then dingy clay-colour, edge whitish, distilling drops in rainy 

 weather. 



Somewhat casspitose. Odour and taste of radish, bitterish. Like A. crus- 

 tiliniformis ; the odour is the same except that it is stronger, but it differs 

 conspicuously in the manifest veil and somewhat distant gills. Var. alba, 

 stem longer, equal, somewhat hollow, fibrous-scaly at the apex, gills dis- 

 tant. A. spiloleucus Krombh, t. 62. /. 3-5. A. sulcatus Lindgr. is an ele- 

 gant form with the margin of the pileus sulcate or rugoso-plicate.
