This is one of the small-leaved species. Their crimpled form, and 

 the lax appearance of the lamellae (arising in part from the fact that 

 the intermediate are so small as to be scarcely seen between the 

 larger), and the non-carinate surface, are the distinguishing charac- 

 teristics. The oririmes within a third of an inch of the margin are 

 often short and rather indistinct ; but others below are an eighth of 

 an inch long.
