confined to the main stems from the base upward to about the 

 region of branching; from here the branches spread so that 

 they grow together only rarely; furthermore, the branches 

 are distinctly cylindric or subcylindric. The spores average 

 •a little shorter than those of related species.

Fructifications solitary or gregarious, erect, coriaceous-soft, 

 pallid, drying warm buff, sometimes with the older portions 

 pale olive-gray, stipitate; stem cylindric, palmately branched 

 into a few — often three — cylindric branches, each or some of 

 which occasionally branch again in similar manner; branches 

 arranged in a plane from flattened end of stem or branch or 

 in a circle about the cylindric end of the stem which is then 

 sometimes perforate and the branches often channelled; 

 hymenium amphigenous, or inferior when the branch is chan- 

 nelled; basidia longitudinally septate, pyriform, 15 X 9 /u; 

 spores colorless, simple, even, curved, 9-15 X 4|-6 n.
