Colonies mo derately growing on Oat meal agar, 2.0-2.5 cm in
seven days at 27 ± 10 C, forming gr owth rings of white sterile mycelia
and black perithecia. On Rabbit dung agar it for ms whit e my celia
with scattered or aggregated black perithecia.
Perithecia superficial , black, semitranslucent, groups of asci can
be seen through the wall, globose to subglobose, 120-150 X 110­
120 m ,« ; attached to the substratum by delicate rhizoids, 50-80 X 2.0­
2.5 m zz; ostiolate, producing at maturity a cirrhus of spore mass
much bigger in size than the perithecial body itself, entangled in the
terminal hairs, 160-200 X 170-260 m,« (Figs. 1, 5) . Terminal hairs are
distinctly of two t ypes (Fig. 1 [ar r ow] , 7-9): (a) very long, straight
to spreading, sometimes with geniculations on its surface, smooth,
septate rarely once or twice, greyish-brown in colour, 1000-1500 X
5.0-6.5 m,« , thick walled, upto 0.5 mp in diameter, tips blunt and light
coloured; (b) short incurved or arcuate, recurved, some irregularly
branched, smooth, to indistinctly rough, septate, 175-280 X 3.00­
3.5 m,«. Both the types of terminal hairs originating around the
ostiole and sometimes at maturity the whole crown of terminal hairs
gets detached from the perithecium (Fig. 6). Lateral hairs few,
short, upto 100-260 X 2.5-3.5 m,«. Asci clavate, 8-spored, evanescent,
35-40 X 8-11 m zz, with narrow stipe (Figs. 4, 11). Ascospores biseriate
to irregular, light brown, ellipsoid, subapiculate, 6.5-7.5 X 4.8-5.0 m,« ,
guttulate, with an apical germ pore (Figs. 3, 11).
Perithecia become empty and partly transparent after the release
of the asci and ascospores (Fig. 2).
The form was isolated from Sambhar deer dung collected from
New Delhi zoo on 12.5.1972. Type cultures of the fungus have been
deposited in the Commonwealth Mycological lnstitute, Kew, England,
and also at the Indian Type Culture Collection, lARI, New Delhi 12.
