Apothecia scattered or more often crowded into congested 
masses several cm. in diameter, at first globose or subglobose, 
expanding and becoming scutellate, reaching a diameter of 4-5 
mm., externally yellowish-green, becoming dark-brown, coarsely 
granular ; hymenium plane or nearly plane with the margin slightly 
elevated, at first greenish, becoming dotted over with the ends 
of the protruding asci, gradually becoming darker, finally almost 
black; asci clavate, gradually tapering below into a long slender 
stem-like base, reaching a length of 200-225 a diameter of 
23-27 /i, 8-spored; spores i-seriate or crowded together so as 
to become partially 2-seriate, ellipsoid with the ends rather 
strongly narrowed, thick-walled, the ends often capped with a 
thickening of the epispore, giving the spore a truncate appear- 
ance, hyaline, becoming violet, finally brown or brownish-black, 
20-24 X 12-14 /i including roughenings; spore-roughenings taking 
the form of wart-like projections, the spaces between appearing 
lighter, giving rise to reticulate markings ; paraphyses about 3 ju. in 
diameter and scarcely thickened above, embedded in greenish- 
yellow mucilaginous substance. 
On burnt places and on charcoal beds.
