Studies in tropical Ascomycetes — II. An interesting Xylaria 

 from Porto Rico

(WITH PLATE 1 8) 



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 s ipervised 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 

 remainder of the day, making the climb at places very slippery 

 _and disagreeable. We succeeded, however, in reaching the top
