236 ANNALS OF THE MISSOURI 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 5-514» in diameter; imbedded 
spores honey-yellow under the microscope, even or rarely 
rough, 5-6» in diameter. 
Fructification 1-4 em. long, 15-2 em. 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 1204 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 114-inch objective 
only rarely a minutely rough wall. H. peniophoroides dif- 
fers by having cystidia.
