330 FUXGUS-FLORA. 



Growing on Bussida adusta and B. foetens. 

 Gregarious or caespitose. The conidia produced "by the 

 diyphae of the pileus are large, elliptical, and smooth. 



Nyctalis asterophora. Fr. (fig. 5, p. 301.) 



Pileus about h in. across, fleshy, conical then hemispherical, 

 flocculose and rather mealy owing to the large, stellate 

 conidia, whitish then tinged with fawn-colour ; gills adnate, 

 distant, narrow, rather forked, straight, dingy ; stem about 

 |- in. long, slender, twisted, stuffed, white then brownish, 

 rather mealy ; spores elliptical, smooth, 3 x 2 /x. 



Nyctalis Asterojjhora, Fries, Hym. Eur., p. 463 ; Cke., 

 Hdbk., p. 344; Cke., Illustr., pi. 11326. 



Growing on old blackened specimens of Bussula nigricans. 



Gregarious or slightly caespitose. The very large stellate 

 bodies borne by hyphae on the upper surface of the pileus 

 iiave been shown by Brefeld to be true conidia, which, under 

 proj)er cultivation, give origin to the fungus. 



II. SPELEAE. 



Nyctalis caliginosa. W. G. Sm. 



Pileus about h in. across, veiy fleshy, margin involute, 

 slightly exceeding the gills, marked with light and dark 

 grey colours when wet, white and floccoso-pruinose when 

 dry; gills decurrent, thick, branched; stem, about 2 in. 

 long, floccoso-pruinose, base naked ; spores elliptical, smooth, 

 4 X 2J /.. 



Nyctalis caliginosa, W. G. Smith, Journ. Bot. 1873, p. 337; 

 Cke., Hdbk., p. 343 ; Cke., Illustr., pi. 1132a. 



On ground in a dark place, among fallen leaves. 



Odour and taste rank and disagreeable, like Polyjyorus 

 squamosus. (W. G. S.) 



Caespitose; stem brown inside, white externally, much 

 swollen at the base, where several are usually more or less 

 grown together. 



A doubtful species. Probably a diseased state of some 

 Clitocyhe. (Cooke.)
