TRICHOLOMA. 179 



yellow tinge, fragile, convex then expanded, unequal, viscid, 

 usually sooty or with a purple tinge, virgate or streaked with 

 fine black lines ; margin thin ; gills rounded behind, often 

 almost free, very broad, 4-8 lines, at length distant, pallid ; 

 stem usually about 3 in. long, and f in. thick, somewhat 

 equal, glabrous, striate, whitish, firm, solid ; spores sub- 

 globose, 4-5 x 4 p, 



Agaricus (Tricholoma) portentosus, Fries, Syst. Mycol., i. 

 p. 39 ; Cke., Hdbk., p. 25 ; Cke., Illustr., pi. 54? 



In pine woods. 



Solitary or gregarious, also rarely forming dense tufts ; 

 inodorous, taste mild, these points separate the present 

 from T. sejunctum. Stem solid, stout, entirely remarkably 

 cartilagineo-fibrous, usually 3 in. long, 1 in. thick, somewhat 

 equal, naked but fibre closely striate, white. Flesh of pileus 

 very thin in proportion to the stout stem ; convex then 

 plane, somewhat umbonate, unequal and wavy, 3-5 in. 

 broad, viscid, virgate from innate, black fibrils ; for the rest 

 even, glabrous, usually sooty, but varies to a violet tint, 

 livid and pale when old; margin thin, always naked. Flesh 

 white, with a faint yellow tinge, fragile, gills rounded, 

 almost free, 3-4 lines up to 1 in. broad, distant, white at 

 first, then becoming yellowish or pallid-greyish. Easily 

 known from other species by the virgate pileus; T. flavo- 

 brunneum and T. albdbrvfmeum differ in having the gills 

 spotted rufescent. T. mrgatum has the pileus absolutely dry. 

 (Fries.) 



Cooke's figures, if the right species, differ in the slender 

 stem being hollow, and coloured like the pileus. 



Tricholoma fucatum. Fr. 



Pileus 2-3 in. across, flesh thin, pallid; convex then plane, 

 somewhat wavy, viscid, lurid-yellowish, variegated with 

 darker stains, disc darker ; gills emarginate, 3-4 lines broad, 

 somewhat crowded, whitish or with a yellow tinge; stem 

 23 in. long, up to \ in. thick, almost equal, fibrillosely 

 squamulose, whitish or with a yellow tinge, stuffed, soft.
