Nectria setosa Ferd. & Winge, Bot. Tidssk. 29: 11. 1908. 
Perithecia superficial, scattered, gregarious or occasionally 2 or 3 crowded together but 
with no trace of stroma, individual perithecia often surrounded near the base with a halo of 
radiating mycelium, at first minute and whitish, large at maturity, attaining a diameter of 
500 # and becoming orange or slightly translucent, subglobose, collapsing, deeply pezizoid 
when dry, sparingly clothed externally with straight, rigid, hyaline (white tothe naked eye) 
hairs which stand erect on all sides giving the species a characteristic appearance ; hairs 
thick near the base, often 25 » in diameter, tapering upward, becoming rather sharp-pointed, 
composed of a dense fascicle of parallel mycelial threads (bearing conidia?), 1004 long; 
asci cylindric or subclavate, 8-spored; spores l-seriate with ends overlapping or, when 
young, partially 2-seriate, 1-septate, hyaline, with an oil-drop in each cell, 15-20 6-82. 
On dead stems of Musa and dead stems and leaves of some undetermined herbaceous plant.

lowish with age; hairs about 2 in diameter, usually roughened externally with minute 
granules but occasionally smooth ; asci cylindric, 8-spored, 40-50 X53 spores 1-seriate,
