suggestive of ringlets in sectional preparations, which sup- 
port (3) the hymenial layer 200-3004 thick, with hyphae 
2-214» in diameter, notably 
curved, branched, and loosely 
interwoven, olive-brown under 
the microscope, bearing in the 
lower part of the layer numerous 
concolorous, globose bodies Пи 
in diameter, and toward the 
outer surface hyaline probasidia 
Па in diameter also, and termi- 
nating at the surface in fine, hya- 
line branches Ту in diameter, with 
recurved or coiled tips; spores 
from deeper portion of hymenial 
simple, hyaline, even, curved, 18 layer; > SE paraphyses; s, 
ў spore. 
X би; spore-bearing organs few- 
celled, straight, cylindric, about 35-40 X Тов, differentiating 
from the probasidia. 
Fructifications 5 em. long, 114 em. broad. 
On trunk of living hardwood tree near the base. Cuba. 
December. Seen but once by the collector. 
S. cirratum has so nearly the color and habit of Hypochnus 
fuscus that it was a surprise to find the specimen a Septo- 
basidium. The color and sinuously divided margin suggest 
S. Langlois. The pillars composed of loosely interwoven 
and curving hyphae are unique and separate this species 
sharply from all our species of the S. pedicellatum group. 
The hyphae are too fine and too curving for S. Spongia.
