spore is in side view, showing at the lower corner a point where the spore was 
attached to the sterigma; lower spore slightly out of median focal plane, surface 
appearing roughened or echinulate. ; 
IG. 2.—Ganoderma pseudoboletum forma tsugae (Murr.) Atkinson, from 
plant on hemlock-spruce, Ithaca, N. Y.; a few of the spores show: the entire
