center, but becomes fairly firm in the subhymenial layers. The stem 
is white pruinose and bears scattered tufts of white hairs at the base 
(fig 2). 
The hymenium surrounds the upper one-third to one-half of the 
fruit body. It is usually smooth, but in some cases shows a tendency 
to the formation of longitudinal ridges. When old or dry, there are 
irregular longitudinal wrinkles, due perhaps to the closer texture of the 
surface layer compared with the very spongy substance within. These 
wrinkles are seen in fg. g, 7 compared with fig. g, g, which represents 
the same specimen when fresh. The hymenium extends to the very 
edge of the free margin of the pileus, where it is replaced abruptly by 
a loose spongy surface of mycelium. Cystidia are numerous. They 
are long and narrow, 60-70 X 4-6, curiously swollen in part or all of 
their length (fg. 8), with often prominent curvatures at their bases 
where they end in the trama of the pileus. Their walls are rather thin 
and colorless, but they contain substances which blacken with osmic 
acid, especially when young. They extend but little above the surface 
of the hymenium, sometimes 4p, often less. The narrow-clavate 
basidia are about 18-24 4p. They are borne upon branching sub- 
hymenial filaments which arise with the cystidia from the trama of the 
pileus, and are much interwoven to form a rather compact layer (jig. 4, 
from crushed preparation), The basidia bear four sterigmata (only 
two and three are shown in Jig. 6), up to 4p in length, with broadly 
elliptical to subglobose (even almost quadrate) spores 3—4 » in diameter 
( Ag. 7). 
This fungus evidently belongs to the genus Crazered/us Pers., as 
defined by Engler and Prantl. It is difficult to associate it closely 
with any of the species described on account of lack of data as to 
structure in most forms. I propose the name C. ¢axophilus for the 
species, from the habitat of the plants. The material has been referred 
to Professor George F. Atkinson, of Cornell University, and to Pro- 
fessor E. A. Burt, of Middlebury College, who agree with me in 
regarding the species as hitherto undescribed.
