smooth, yellowish, but paler at apex, where striate markings from the gills may 

 be present, viscid ; the ring is viscous, incomplete, and formed by the remains 

 of the glutinous veil which soon disappears. 





Figure 35. — Hypholoma appendiculatum. (Edible.) (From G. F. Atkinson) 



The cap is 1 to 1% inches broad ; the stem is 2 to 3 inches long and 2 to 3 

 lines thick. 



This species is remarkable for the uniformly hemispherical cap. It occurs 

 commonly on dung or in well-manured ground. It is not to be recognized as 

 an edible species.
