Studies in tropical Ascomycetes—II. An interesting Xylaria 
from Porto Rico

(WITH PLATE 18) 
During a recent collecting trip to Porto Rico* the writer 
had the opportunity of visiting one of the most interesting and 
fruitful collecting grounds for fungi to be found on the island, 
the Luquillo Mountains. This trip was made possible through 
the efforts of Mr. E. M. Bruner, Forester of Porto Rico, who 
placed at our disposal the Forest Ranger’s cabins, located at an 
elevation of about 1200 feet. This camp consisted of two cabins, 
one of boards with metal roof and the other a rough building 
with thatched roof. The cabins were provided with cots, 
utensils, and charcoal stoves for cooking. Mr. Bruner acted 
as host and supervised the house-keeping activities during our 
stay here. The party consisted of Dr. and Mrs. Britton, Mr. 
Bruner, Professor Dale of the University of Porto Rico, and the 
writer. 
The trip from San Juan to Mameyes was made by auto- 
mobile and the ascent from this point to the Forester’s camp 
on foot or by horse. Arriving at the camp soon after noon on 
Friday, February 23, the remainder of the afternoon was spent 
in the vicinity of the camp site. 
Saturday, February 24, an expedition was planned to the 
top of El Yunque, for a long time supposed to be the highest 
peak in Porto Rico but now known to be exceeded by several 
others. The ascent was made much easier by reason of the trail 
of broken stone which had been constructed under the super- 
vision of Mr. Bruner for a greater part of the distance. Soon 
after the expedition started, it began to rain, as it nearly always 
does at this elevation, and a slow drizzle continued during the 
Temainder of the day, making the climb at places very slippery 
and disagreeable. We succeeded, however, in reaching the top
