COPRINUS. 325 



Coprinus nycthemerus, Fries, Epicr., p. 251 ; Cke., Hdbk., 

 p. 232; Cke., Illustr., pi. 682s? 



On dung and manured ground. Subcaespitose. In Cooke's 

 figures quoted above the pileus is in every specimen tawny 

 at the disc and becoming very pale dull yellow towards the 

 margin, whereas Fries distinctly states in italics " griseo, 

 disco fusco," hence it is not certain that the species of Fries 

 is depicted. 



Coprinus radiatus. Fr. 



Piletis 2-3 lines across, exceedingly delicate and em- 

 phemeral, cylindrical, then campanulate, at length plane, 

 at first covered with a greyish down, soon splitting, radially 

 plicate, yellowish, disc tawny ; gills free, few and distant, 

 narrow, blackish; stem ^1 in. high, filiform, hyaline, 

 becoming glabrous, whitish ; spores 7-8 x 5 /z. 



Coprinus radiatus, Fries, Epicr., p. 251 ; Cke., Hdbk., 

 p. 232 ; Cke., Illustr. pi. 682 A. 



On dung. Distinguished by its very small size and the 

 plane, fissured pileus. Very ephemeral. 



On horse-dung, often on the under side, in grassy woods, 



&c. Very tender, so that a breath destroys it. Pileus 1-2 



lines broad, at first digitaliform, yellowish, the apex obtuse, 



darker, striate and downy, when full grown pale-brown, or 



nearly colourless, the centre sometimes dimpled, strongly 



furrowed, edge notched and often split in a radiated 



manner, so as to appear like the spokes of a wheel ; gills 



about 10, with minute smaller ones in the interstices. Stem 



j 1-3 in. high, very slender, quite filiform, smooth, but 



: sometimes fibrillose and tomentose, dusky or colourless, a 



little thickened at the base, where it is slightly downv.
