On dung, &c., somewhat resembling Panaeolus phalaenarum 

 and P. papilionaeeus ; distinguished from the former by the 

 pileus not being viscid, and from the latter by the grey 

 stem. Fries mentions a small form with linear gills. 



Stem fistulose, straight, 2—3 in. long, 1 line thick, equal, 

 fragile, glabrous, smoky-grey, apex even, pruinose. Veil 

 appendiculate near the margin, white, fugacious. Pileus 

 rather fleshy, parabolic, then campanulate, not expanded, 

 obtuse, 1 in. high, hygrophanous, not viscid, hence always 

 opaque, but in rainy weather, moist and smoke-colour or 

 smoky-grey, livid and rather silky when dry, sometimes 

 when in full vigour covered with fibrils, especially near 

 the margin. Gills adnate, ascending, crowded, greyish- 

 black, edge same colour. (Fries.) 



Panaeolus papilionaceus. Fr. 



Pileus |-1 in. across, slightly fleshy, hemispherical, obtuse, 

 glabrous, when dry cracked into minute squamules, pale 

 grey with a tinge of rufous, especially at the disc ; gills 

 broadly adnate, 8 lines broad, at length plane, at length 

 blackish; stem 3-4 in. long, 2 lines thick, equal, smooth, 

 whitish, apex powdered with white meal, hollow; spores 

 elliptical, H-12 X 7 fn.
