236 ANNALS OF THE MISSOUBI BOTANICAL GARDEN 



in diameter, honey-yellow under the microscope, forming in 

 the interior of the layer and at the surface of the hymenium 

 numerous dichotomously branched branches with subulate 

 tips which resemble the antlers of a stag; basidia bearing 4 

 spores on sterigmata; basidiospores hyaline, or very nearly 

 so, under the microscope, rough-walled or aculeate with very 

 short points, globose, body 5-5%/x in diameter; imbedded 

 spores honey-yellow under the microscope, even or rarely 

 rough, 5-6/x in diameter. 



Fructification 1-4 cm. long, %-2 cm. broad, often in lobate, 

 connected masses. 



On fir logs. Washington and British Columbia. July. 



The basidia of this species show best in the recent col- 

 lection 120iLi thick, from which the illustration has been made. 

 The stage of the type is much thicker apparently by growth 

 of great numbers of the antler-like hyphal branches which 

 conceal the basidia. This species resembles closely in habit, 

 structure, and spore characters Thelephora pallescens Schw. 

 of eastern North America, except that the spores of T. 

 pallescens show by magnification with a li/2-inch objective 

 only rarely a minutely rough wall. H. peniophoroides dif- 

 fers by having cystidia.
