The perithecia are large, 4-5 mm. long when elongated, 2-3 mm. 
across when more or less circular. 
Lophodermium velatum, Berk. 
Gregarious, crowded on small pale spots ; perithecia blackish, 
flattened and covered by the cuticle, smooth, about 5 mm. long, 
uniform in size, the long axis in all instances parallel to the long 
axis of the stem of host; asci broadly cylindrical, terminating 
abruptly in a very short, oblique stem; apex somewhat acute, 
8-spored ; spores fasciculate, nearly as long as the ascus, with a 
spiral twist, filiform, or with the apex slightly incrassated, 75-80 x 
1-5 p ; paraphyses numerous, very slender; apex narrowly 
clavate, colourless. 
Hysterium velatum , Berk, in Herb. This species has not been 
published before, I believe.

this species has never been published.
