On the ground in woods, &c. 



Fries says that there are two forms : (a) Stem fibrillose ; 

 on the ground in woods. (6) Stem short, glabrous; in 

 sunny places amongst gravel. 



Stem fistulose, thin, scarcely 1 line thick, equal, at first 

 subfibrillosus, then glabrous, pale bay, apex rather mealy ; 

 pileus slightly fleshy, obtuse, hemispherico-convex, glabrous, 

 in full vigour of growth the margin is striate, dark rufous 

 or purple-brown, when dry becoming very pale and without 

 striae. Gills ad nate, subdecurrent, triangular, plane, umber
