Asci 35–60 μm × 8–10 μm, 8-spored, bitunicate, subcylindrical to clavate, sessile to very short-pedicellate, narrowly rounded at the apex.

Material examined INDIA, Green Lands, Coorg, on leaves of Bambusa arundinacea (Poaceae), 10 March 1968, B.N. Muthappa (BPI 610067, holotype).

Economic significance – Members of the genus Cerodothis cause leaf spot by producing yellow microconidia on Bambusa bambos stands in Karnataka State (Muthappa 1969) and on Dendrocalamus strictus and Thyrsostachys siamensis stands in Kerala State (Mohanan 1994a, b).
