SOME PORTO RICAN PARASITIC FUNGI 
Philip Gasman 
(With Plate 171, Containing 7 Figures) 
The following descriptions and notes have been made upon 
Porto Rican fungi collected by Dr. F. L. Stevens during the 
years 1912 and 1913. A description of the material contained in 
this collection has already been given in a paper by Miss Esther 
Young.^ The types and cotypes of new species have also been 
distributed as set forth in that article. 
Thanks are due to Dr. F. L. Stevens for his many helpful 
suggestions, without which the work would not have been pos- 
sible. The species of hosts, with few exceptions, have been de- 
termined by Dr. N. L. Britton and Mr. Percy Wilson, of the 
New York Botanical Garden, and to them also I wish to express 
my thanks.
