Epiphyllous, forming velvety black colonies 2-4 mm. diam., fre- 
quently confluent. Hyphae branched, chestnut brown (E,. XIY) 8-11 /x 
thick; capitate hyphopodia very numerous, closely crowded, opposite or 
alternate, 18-28 /x long, terminal cell ovate or globular, obtuse, 10-15 /x 
thick ; mucronate hyphopodia not so numerous, up to 25 /x long. Perithecia 
congregated in the centre of the colony, but not crowded together, black, 
globose, collapsing somewhat when dry, asperulous, 250-300 fx diam. 
Mycelial setae very numerous, 200-300 /x long, 8-11 /jl thick, opaque at the 
base, dividing above into two long (up to 130 /x) spreading, slightly incurved 
branches, these branches being again divided into two branches of various 
length (30-80 /x), bifurcate at the apex. Asci ovate 50-60 x 28-40 /x, 2-3- 
spored ; spores oblong, broadly rounded at both ends, 4- septate, constricted 
at the septa, chestnut brown, 45-55 x 15-20 /x.
