36 AGARICUS. 



Tricholoma. delicately squamulose at the apex. Gills emarginate, broad, some- 

 what distant, shining white. 



Odour almost that of new meal ; taste bitterish. Differing widely from A. 

 equestris, &c., in the flesh being fragile. With this there is commonly con- 

 founded a fungus almost of the same colour, but mild, with longer striate stem, 

 and with tan-coloured, black-streaked pileus, 10-12.5 cent. (4-5 in.) broad, 

 which is perhaps a form of A. portentosiis disguised by difference of colour. 



In woods, chiefly pine. Uncommon. Autumn. 



Pileus dirty yellow or nearly white ; gills whitish and thickest near the stem, 

 somewhat flattened as it were by separating from it in a peculiar manner, and 

 partly adhering to each other. Sow. Spores 6 mk. IV.G.S. Name 

 sejunctus, separated. From the peculiar manner in which the gills separate 

 from the stem. Sow. t. 126. Fr. Monogr. i. p. 52. Hym. Eur. p. 48. Icon,

62. A. portentosus Fr. Pileus 7.5-12.5 cent. (3-5 in.) broad, 

 fuliginous, livid, sometimes violaceous, fleshy, but thin in com- 

 parison with the stoutness of the stem, convexo-plane, somewhat 

 umbonate, unequal and repand, viscid, streaked with black lines 

 (innate fibrils), but otherwise even and smooth, the very thin 

 margin naked ; flesh not compact, white, fragile. Stem com- 

 monly 7.5 cent. (3 in.), often 10-15 cent. (4-6 in.) long, 2.5 cent, 

 (i in.) thick, stout, solid, the whole remarkably fibrous-fleshy, 

 somewhat equal, naked, but fibrilloso-striate, white ; the base, 

 which is occasionally attenuato-rooted, villous. Gills rounded, 

 almost free, 6-8 mm. (3-4 lin.) to as much as 2.5 cent, (i in.) 

 broad, distant, white, but varying, becoming pale-grey or yellow. 



Solitary or gregarious, even csespitose ; inodorous, taste mild. Sometimes 

 on naked sandy ground a smaller form occurs with a somewhat bulbous stem.

63. A. fucatus Fr. Pileus 5-7.5 cent. (2-3 in.) broad, rarely 

 more 10, 12.5 cent. (4, 5 in.), becoming lurid-yellow, or cinereous- 

 light-yellow, variegated with tiger-spots, the disc darker, fleshy, 

 convexo-plane, obtuse, often irregular, viscid, but readily dry and 

 opaque, even, smooth and not streaked vi\\h. innate fibrils; margin 

 thin, naked, scarcely inflexed ; flesh thin, pallid, at length fragile. 

 Stem 5-7.5 cent. (2-3 in.) long, 8-12 mm. (4-6 lin.) thick, stuffed, 

 soft, ascending or straight, somewhat equal, externally at first
