 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- 

 cystidia. 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 

 crush 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 

 2X2| 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.
