Apothecia gregarious or densely crowded, at first closed and 

 globose, at maturity scutellate, reaching a diameter of 5 mm. 

 to 1 cm., externally appearing brown from the dark-colored 

 hairs; hymenium slightly concave, almost plane or occasionally 

 slightly convex, bright-red, almost scarlet; excipulum composed 

 of large roundish or slightly angular cells which form a palisade 

 near the margin, the loose ends of which project, giving rise to a 

 fringe-like border of club-shaped hyphae; hairs ranging from a 

 few pale cells when young to long rigid setae at maturity, dark 

 reddish-brown, reaching a length of 1 mm. and a diameter of 

 35 /x at the broadest point, closely septate, the walls 3-4 ^u thick, 

 constricted below near the point of attachment; asci cylindric 

 above, gradually tapering below into a stem-like base, reaching 

 a length of 325-350 /x and a diameter of 26-27 n, 8-spored but 

 part of the spores often remaining undeveloped; spores 1-seriate, 

 usually obliquely arranged in the ascus, at first smooth and 

 usually containing one large oil-drop, 12-14 X 23-24 m, hyaline, 

 at maturity becoming sculptured; spore-sculpturing consisting 

 of rather coarse warts; warts about 2 /i in diameter; paraphyses 

 rather stout, about 3-4 p. in diameter below, strongly and rather 

 abruptly enlarged above, reaching a diameter of 10/x at their 

 apices, densely filled with minute orange granules. 



On very damp soil, more rarely on rotten wood. 



Type locality: Europe.
