CLASSIFICATION 145 



C. acervata. — Cap 2-3 in. across, obtuse, pale flesh-colour, pale 

 when dry ; gills tinged flesh-colour, then whitish, closely crowded, 

 narrow ; stem 2-4 in. long, rufous or sometimes brown, smooth. 



Densely tufted, stems numerous, covered with white down at the 

 base, otherwise polished. Differs from C. confluens in the polished 

 stem. 



Marasmius erythropus much resembles this species but differs in 

 the broad distant gills. 



At the base of trunks, etc. 



C. dryophila (PI. XII, fig. 6). — Cap 1-2 in. across, convex, then 

 expanded and obtuse, reddish bay or pale tan ; gills almost free, 

 pallid ; stem 1-2 in. long, smooth, yellowish or rufescent, base often 

 swollen when growing in a damp place. 



Distinguished from allies by the narrow, crowded gills, and obtuse 

 cap. 



Among fallen leaves, on rotten wood, etc. 



C. aquosa. — Every part honey-colour, hygrophanous ; cap about 

 I in. across, tough, plane, edge densely striate, gills much crowded ; 

 stem i|-2| in. long, polished. 



Damp woods among moss. 



C. extuberans. — Cap f-ii in. across, convex, then expanded, with a 

 prominent umbo, bay or umber ; gills nearly free, crowded, narrow, 

 white ; stem 2-3 in. long, smooth, pallid, rooting. 



Solitary, tough, inodorous. Differs from C. protrada in the large 

 umbo. 



On rotten wood, and on the ground near trunks. 



C. cxsculpta. — Cap 1-2 in. across, convex, umbilicate, tawny- 

 brown ; gills closely crowded, sulphur-yellow ; stem about i in. 

 long, clear sulphur-yellow. 



Known from allied species by its toughness, and by the clear 

 sulphur-yellow gills and stem. 



On dead wood, etc. 



C. macilenta. — Cap about i in. across, convex, then plane, smooth, 

 dark yellow ; flesh yellow ; gills crowded, narrow, pure yellow ; stem 

 about il in. long, smooth, bright yellow, tough, slightly rooting. 



Differing from every other species in the yellow colour throughout. 

 Allied structurally to C. esculenta. 



In pine woods, on leaves, etc. 



C. clavus. — Cap 1-4 lines across, conically convex, then plane, 

 somewhat papillate, smooth, shining, edge striate, orange-scarlet, 

 disc darker ; gills white, rarely tinged yellow ; stem up to i in. 

 long, slender, smooth. 



The smallest species in the genus, distinguished by the 1 •right- 

 coloured cap. Mycena acicula differs in the j^ellow gills and rooting 

 stem.
