Plants gregarious, or crowded, at first subglobose, expanding 
and becoming plane or with the hymenium a little concave with a 
slightly elevated and often fringe-like margin, bright red, with- 
out and within, margin lighter, almost white, 1-5 mm. in diameter 
(usually about 3 mm. at maturity) asci cylindric or subcylindric, 
about 20-22 ix in diameter; spores i-seriate, at first smooth and 
usually containing one large oil-drop, at maturity becoming deli- 
covering the entire surface of the spore, meshes of the reticula- 
cately roughened, roughenings taking the form of reticulations 
tions 2-4 fi, rarely 5 or 6 /a in diameter, ranging from 3-6-sided, 
with the sides usually of unequal length but occasionally giving 
rise to almost perfect hexagonal figures, ridges very even and 
delicate, less than 1 fi broad, the ridges giving rise to a perfect 
unbroken net-work about the spore and very shallow as indicated 
by the roughenings about the periphery of the spore, entire spore 
15-22 /x in diameter (usually about 20-22 /x at maturity), hyaline; 
paraphyses thickened above and filled with orange granules. 
On damp soil usually among moss plants. 
Type locality: Brest, France. 
Distribution: New York to Colorado; also in Europe.
