trees, the patches varying in size from 3 cm to 20 cm in di¬ 
ameter. When moistened they have a dirty blackish color and 
the papillae are very prominent; when fully mature it dries 
down to a hard shining black mass, forming a thin crust and 
now shows nothing of its previous form. 
Most of the specimens collected have been found on hickory, 
although specimens have also been found on elm, poplar, and 
cherry. Common, Madison and vicinity.

Carpophore convex, pulvinate, gyrose, cerebriform, gelatin¬ 
ous, basidia, globose, soon longitudinally or obliquely cruciately 
partite, sterigmata elongated, thick; spores for a long time con¬ 
tinuous, then once septate, reniform, each locule on germination

a crown of straight, rod-like sporidiola.
