the Philippine Islands distributed in Sydow, Fungi Exot. Exs.

from E. D. Merrill, 3508, and the other by H. M. Curran, For- 
estry Bureau, 8907. 
There is a close resemblance in aspect and coloration between 
the above-mentioned specimens of A. rugosissima and our 
American Phlebia strigoso-zonata, but the latter has simple 
basidia bearing 4 spores at the apex on slender sterigmata. 
The demonstration of these basidia is easy, for in a fertile speci- 
men the mature basidia protrude beyond the dense, compact, 
dark layer of hymenial hairs and stand out conspicuously, bear- 
ing their spores. One should disregard the difficult structure 
of this dark layer and run along its edge in the section for the 
more or less scattered exserted basidia. My demonstration 
has been confirmed many times by members of my classes in 
mycology who have used fertile specimens of this species in 
laboratory work in determination of genera. 
Hence Merulius strigoso-zonata Schw. is not a species of 
Auricularia but should be included in PAlebia on account of the 
configuration of its hymenium and simple basidia. The present 
status of this species so far as known to me from examination 
of authentie specimens is as follows:
