SEAVER: STUDIES IN TROPICAL ASCOMYCETES 309 
The species has been found only in the one locality in Porto 
Rico. The host on which the fungus preys, however, occurs 
from Cuba to Hispaniola and Porto Rico and in the Lesser 
Antilles from Saba to Grenada. Assuming that the fungus is 
restricted to the one host, as it seems to be, its possible range 
of distribution then is as indicated above. The only economic 
bearing which the fungus could have is in connection with the 
destruction of the seeds of the host. How important this can 
be cannot be stated. 
Our material from Porto Rico agrees quite closely, so far as 
we can judge from the description, with Xylaria palmicola 
Winter,* described from Brazil. No specimens of the South 
American species have been seen and the host of that species 
isnot named. The fact that the host of the Porto Rican species 
does not occur in South America, so far as we know, leads the 
writer to regard ours as distinct. The species is dedicated to 
Mr. Bruner and a description appended.

Stromata growing upon and their mycelium filling the seeds
