Agaricus phalaenarum, Bull., t. 58. 



On dung. Closely allied to Panaeolus papilionaceus, but 

 larger, the pileus Yiscid and yellowish clay-colour, like 

 Anellaria separata, stem reddish. 



Exactly intermediate between Anellaria separata and 

 Panaeolus papilionaceus ; differs from the first in the absence 

 of a ring, and the equal, rufescent stem, the much more 

 convex pileus appendiculate at the margin ; the fragments, 

 however, are fugacious and not usually seen ; from the latter, 

 present species is known by the veil, viscid pileus, and 

 whitish clay-colour. (Fries.) 



** Pileus not viscid, suhflocculose when dry. 



Panaeolus retirugis. Fr. (fig. 3, p. 303. ) 



Pileus about 1 in. across, at first almost globose, then 

 hemispherical, subumbonate, minutely mealy, opaque, moist, 

 furnished with anastomosing raised ribs, pinkish tan-colour ; 

 margin with irregular fragments of the veil attached ; flesh 

 rather thick ; gUls adnexed, ascending, 2 lines or more 

 broad, greyish black; stem 2-4 in. long, about 2 lines thick, 

 equal, pruinose, purplish flesh-colour, hollow ; spores elliptic- 

 fusiform, 11-13 X 1 fi..

Agariam carbonarius, Batsch, fig. 91. 



On dung. Distinguished amongst the species of Panaeolus 

 by the raised ribs on the pileus and its appendiculate margin. 

 The pileus is sometimes greyish, when it approaches P. 

 phalenarum ; the latter, however, has the pileus even. Closely 

 resembling, superficially, Psathyra corrugis, which is, how- 

 ever, distinguished by the violet-black gills. 



Pileus 1-2 in. broad and high, at first obtuse, conic, re- 

 ticulato-rugulose ; at length campanulate, dark cinereous, 

 Uvid when dry; the ring broken into triangular loops or 

 laciniae, fringing the margin, which is minutely downy and
