94 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
On the ground in frondose woods. New Hampshire to North 
Carolina and Tennessee, and in Japan. July to October. 
Distinguishing characters of this species are the radially 
arranged fibrils and fibrillose ridges of the upper surface of the 
pileus, bright yellow hymenium of fresh specimens, small sub- 
globose spores, and absence of zonation, cystidia, and gloeo- 
eystidia. "These characters separate the species from S. auran- 
tiacum and S. Ravenelii and from specimens of S. diaphanum 
which have become discolored in the herbarium. The sections 
erush out and tissues spread apart when slight pressure is applied 
to the cover glass—a character unusual in stipitate Stereums. 
The specimen from Tennessee consists of two dimidiate pilei 
2X25 cm. At Amherst, Massachusetts, Professor Anderson 
saw perhaps a thousand fructifications of this growing in an 
area of a square rod; to him I am indebted for the color obser- 
vations on fresh specimens and for specimens in growing condi- 
tion showing the colors and also the fact that the consistency 
of the pileus is not fleshy enough for inclusion of this species 
in Craterellus.
