Stromata gregarious or occasionally crowded, seated on a sulfur-yellow subiculum, dis- 
coid, fleshy, with the margin elevated from the substratum; young plants substipitate; stem 
short, about 1 mm. thick and 1-2 mm. high, gradually expanding upwards into the sub- 
patellate stroma; stroma plane to a little concave or convex, dull-yellow, slightly punctate 
with the darker necks, 1-4 mm. in diameter; asci cylindric; spores becoming smoky- 
brown, 4X 54 in diameter. 
On bark.

Stromata appearing first as specks of white tomentum, with a brick-red spot appearing 
in the center, finally becoming fleshy, rather thick and entirely brick-red without, and 
white within, subpatellate, convex, becoming wrinkled when dry, punctate with the necks 
of the slightly protruding perithecia, finally dusted over with the greenish spores; asci cyl- 
indric; spores about 4 in diameter, the lower of each pair a little larger than the upper.
