by Johnston & Seaver, 1370, and the other is the type collection, 
which was taken from a phanerogamic specimen in the Field

II. Ravenelia Ingae (P. Henn.) Arth. N. Am. Flora 7: 
132. 1907. 
On Mimosaceae: 
Inga vera Willd., Monte Montosa, Oct. 13, 1912, p7<5, Oct. 
14, 1912, 28d ; Monte Alegrillo, June 20, 2376. 
The fungus on the same host has also been collected in Porto 
Rico at Ponce, O. W. Barrett, Aug., 1904. No other West Indian 
collections are known to the writer. 
On some of the leaves the fungus forms loose brown masses, 
consisting mostly of spores, that have the appearance of insect 
ejecta. The resemblance is aided by the leaf being puffed and 
broken at these places, the spots often being a centimeter across.
