No attempt is here made to list the synonyms of this common 

 and well-known temperate species, which is probably confined to 

 the higher elevations of our tropics, being abundant at Cinchona, 

 Jamaica.

2. Clitocybe (Fries) Quel. Champ. Jura Vosg. 48. 1872 



The distinguishing feature of this very important temperate 

 genus is its decurrent gills. Some of the species, however, do not 

 show this character very conspicuously.
