CLASSIFICATION 217 



** Stem lateral, or springing from the edge of the cap. 



C. muscigenus.- — Cap thin, flaccid, more or less spoon-shaped, 

 horizontal and often depressed behind, smooth, usually zoned, 

 yellowish brown, then greyish white when old and dry, \-\ in. 

 across ; gills radiating, distant, branched, narrow, coloured 

 like the cap ; stem lateral, slender, base downy, 1-2 lines 

 long. 



Differs from C. retirugis, which also grows on mosses, by the 

 presence of a stem, and from C. glaucus by its habitat and brownish 

 colour when moist. 



Growing attached to the larger mosses, Hypnum, etc. 



C. glaucus. — Entirely grey. Cap thin, strap-shaped or fan- 

 shaped, silky, not zoned, up to | in. across ; gills radiating from the 

 point of attachment of the stem, distant, narrow, thick, forked ; 

 stem lateral, expanding into the cap, slightly pruinose, about i line 

 long. 



Distinguished from C. muscigenus by growing on the ground, and 

 being altogether grey. 



On the ground in damp places. 



*** Cap quite sessile, resupinate or gills uppermost. 



C. retirugis. — Cap thin, more or less fan-shaped or irregular, 

 edge wavy and lobed, greyish white, subsessile or rarely extended 

 behind into a short, flattened, stem-like base, attached by fibrils, 

 |— I in. across ; gills radiating from the centre, very thin, anasto- 

 mosing. 



Growing on mosses, Hypmtm, etc. 



C. lobatus. — Cap thin, horizontal, more or less orbicular, edge 

 deeply lobed, sessile, brownish, pale when dry ; gills radiating from 

 a point, thick and fold-like, branched, distant. 



Cap |-i in. across, distinguished by being quite sessile, and edge 

 of cap deeply lobed. 



Growing on mosses in swamps, etc, 



Nyctalis 



Cap symmetrical ; gills adnate or decurrent, thick, soft, edge 

 l:)lunt ; stem central ; spores colourless. 



Parasitic on the larger fungi. The cap is densely mealy, due to 

 the presence of numerous large conidia. 



N. parasitica. — Cap conical, then expanded, unequal, densely 

 mealy, due to the presence of a layer of conidia, grey, up to 

 f in. across ; gills adnate, thick, distant, anastomosing, brownish ; 

 stem often wavy, downy, whitish, 1-3 in. long. 



Growing on Russula adusta, R. fcetens, etc. Gregarious. The 

 large conidia on the cap are elliptical and smooth.
