346 BRITISH FUNGI 



C. dilectus. — Cap cylindrical, then campanulate, often becoming 

 revolute, finely striate, rosy, then tawny, mealy or floccose, about 

 \ in. across, sometimes more ; gills free, reddish brown, then black ; 

 stem about 2 in. long, whitish and sprinkled with red or deep 

 orange powder, shghtly bulbous ; volva reduced to whitish squa- 

 mules or down. 



On scorched ground, soil in plant-pots, on rotten twigs, etc. 



C. roseotinctns. — Cap cylindrical, eventually revolute, silky, 

 striate, brownish, densely covered with rose-coloured meal, about 

 \ in. across ; gills adnexed, broad, deliquescent ; stem bulbous and 

 white floccose, densely covered with rose-coloured meal when 

 young, about i in. long. 



Known by the deep rose-coloured meal on cap and stem. It is 

 very doubtful whether this is distinct as a species from C. dilectus. 



On the ground. 



** Ring imperfect, no sheathing volva, sqitamules on cap minute, 

 adpressed. 



C. atramentariiis (PI. XXV, fig. i). — Tufted. Cap 2-3 in. high 

 and same when expanded, often plicate and lobed at the edge, 

 greyish, silky, disc or centre brownish and minutely rough ; gills 

 free, crowded, white, then black with purple tinge ; stem 4-6 in. 

 high, white, silky, shining, ring near the base e\'anescent. 



There is a prominent ridge near the base of the stem, due to 

 pressure of edge of cap when young. Edible when young. 



About decaying stumps and on rich soil. Not on dung. 



C. soboliferus. — Close to C. atramentarius, differing mainly in the

 remainder greyish brown ; gills attached to stem, blackish umber ; 

 stem 4-5 in. long, whitish, ring indistinct or absent.

 cap. 



On trunks and stumps. 



var. rimososquamosus. — Cuticle of cap torn into large angular 

 patches, showing the paler flesh. 



*** Universal veil flocculose or felly, at first continuous, then broken
