481] MELIOLA IN PORTO RICO — STEVENS 13 



specimen No. 3849 of Rabenhorst's Fungi Europaei. I have described 

 some Meliolas as varieties though I am inclined to believe that in several 

 instances they will eventually prove to be really as distinct specifically 

 as many other forms that are recognized as species.
