CLASSIFICATION 105 



** Gills becoming tinged red or grey, edge often spotted. 



T. vaccinum. — Cap campaiuilate, then expanded, unibonate, 

 becoming broken up into small spreading scales, or torn into ad- 

 pressed scales, dry, rufous, 3-5 in. across, flesh thick and, like that 

 of the stem, white, then reddish ; gills rather distant, broad, whitish, 

 then spotted and rufescent ; stem hollow, more or less corticated, 

 whitish with a rufescent tinge, about 3 in. long. 



Differs from T. imhricatmn in the umbonate cap, and hollow 

 stem with the apex quite naked. 



In pine woods, etc. 



T. imbricatmn. — Closely resembling T. vacciiunii in size, colour, 

 and general appearance. Differing in the cap not being at all 

 umbonate, and in the stem being solid and having the apex covered 

 with white, pulverulent down. 



In pine and mixed woods. 



T. inuniindum. — Cap rather fleshy at disc, edge incurved and very 

 thin, when dry dingy white with darker stains, 2-3 in. across ; gUls 

 grey with pink tinge ; stem dingy white, fibrillose, about 2 in. long. 



Known by the dark gills and thin cap. The gills separate readily 

 from the cap, as in Paxillus. Every part of the fungus becomes 

 black when bruised. 



Among short grass in pastures. 



T. inodermium. — Cap conico-campanulate, acute, then more 

 convex and somewhat umbonate, becoming broken up into fibrils, 

 etc., rufous-brown, 1-2 in. across ; gills very broad and ventricose, 

 white, spotted reddish when bruised ; stem white with a rufous 

 tinge, hollow upwards, about 3 in. long. 



In damp, dense pine woods. 



T. hordum. — Cap campanulate, then expanded, at length flat- 

 tened, somewhat umbonate, and the edge becomes upturned, un- 

 equal, wavy, smooth, surface soon cracking or breaking up into 

 scales, grey, about 3 in. across ; gills broad, rather distant, white, 

 then greyish ; stem smooth, whitish, about 3 in. long. 



Inodorous, mild, rigid, and fragile. 



Under beeches, etc. 



T. murinaceum. — Cap 2-3 in. across, more or less umbonate, 

 silky, grey, sometimes cracked into scales ; gills broad, distant, 

 grey ; stem pale grey, with darker minute scales. 



Differs from T. terreum in squamulose stem. 



In woods. 



T. terreum (PI. VIII, fig. i). — Cap 2-3 in. across, umbonate, 

 squamulose, bluish grey ; gills pale grey, edge minutely jagged ; 

 stem fibrillose, whitish, 1-3 in. long. 



In woods. 



var. orirubens. — Edge of gills rose-colour. 



var. atrosqiiamosiis. — Cap grey, covered with small black scales.
