Cerodothis aurea Muthappa, Mycologia 61: 737 (1969)                                                                               Fig. 1

Index Fungorum number: IF327982; Facesoffungi number: FoF 06673

Saprobic on leaves of Bambusa arundinacea. Sexual morph: Thyriothecia 500 × 250 μm, multilocular, pale yellow to brown, epiphyllous, sub-epidermal, comprises dark brown to brown cells of texura angularis (= cylindrical to cuboid cells). Locules globose to subglobose, ostiolate, in transverse section, ectostroma bifurcate 40–76 μm diam., endostroma rounded, 102–178 μm × 160–230 μm; locules 34–76 μm × 51–85 μm; ostiole 34–51 μm long. Asci 35–60 μm × 8–10 μm, 8-spored, bitunicate, subcylindrical to clavate, sessile to very short-pedicellate, narrowly rounded at the apex. Ascospores 12–15 μm × 3–4 μm, crowded, 2–3-seriate, 1-septate, narrowly obovoid to fusiform, hyaline, smooth-walled. Asexual morph: Undetermined.

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).
