Fructifications resupinate, adnate, broadly effused, thin, 
drab-gray to light drab, the margin of the same color or paler; 
hymenium bearing more or less numerous granules or papillae 
with whitish tips; in structure 100-200 » thick, composed of 
interwoven hyaline hyphae 2-215 v. in diameter, and some masses 
of crystalline matter; granules 200-300 v high by 100 v in di- 
ameter at the base, composed of a few hyphae and much crystal- 
line matter in masses; basidia longitudinally septate, 16-20 x 
8-10 v; spores white in collection on slide, flattened on one side, 
8-10 x 5-6 v 
Covering areas 6 cm. and more long, 3 cm. and more wide. 
On bark of decaying frondose wood. Louisiana and the West 
Indies. October to March. 
This species has been confused in American mycology with 
Grandinia ocellata, from which it is distinct by its longitudinally 
septate basidia; it may be easily separated from our other spe- 
cies of Heterochaete by its livid (drab of Ridgway) color. Nearly 
twenty years ago I shared with Bresadola a specimen of this 
fungus received from Langlois. The interruption to corres- 
pondence by the war prevented my calling Bresadola’s attention 
to the fact that a portion of another gathering, communicated 
by Langlois to Patouillard, was published by the latter as a new 
species, hence the synonymy.
