Black. Perithecia rather small, globose or subglobose, con- 
stricted into a neck at the upper extremity, frequently flatten 
at Ше base, 1924 high X 198и broad (126-232 X 135-236), 
discharging black spore cirrhi many times longer than the peri- 
thecium, producing no differentiated rhizoids, but seated among 
and upon the stalks and branches of the conidiophores. Lateral 
hairs rather numerous, very variable in length but nearly always 
short, tapering near the tips only, branched and ampullate as are 
the terminal hairs, very dark olive-brown to black below, about 
3.2 и in thickness near base, colorless and frequently septate near 
their tips. Terminal hairs extremely variable in length, straight, 
stiff, dark olive-brown to black except at the ampullae and extreme 
tips, remotely septate, frequently with an angular swelling at the 
septum, profusely and sympodially branched, each individual 
axis producing one or two lateral branches beyond the point of 
origin of which the axis terminates in a somewhat swollen, club- 
shaped colorless ampulla. Asci linear, cylindrical, 8-spored, 
65 ХІ Та, pars sporif. 45 и. Spores monostichous, when young 
pale olive with a greenish tinge, when mature dark olive-brown 
to black, regularly or irregularly circular in face view, lenticular, ` 
with girdle apparent when seen in profile, 8.1 X 7.7 в (7.279 x 
72-81), when seen edgewise 4.5-5.4 и broad.
