Biju inHosagoudar, J. Mycopathol. Res. 43: 26, 2005 (Fig. 43).Colonies epiphyllous, dense, crustose to velvety,scattered, up to 2mm in diameter, rarely confluent.Hyphae substraight to flexuous, branching irregularat acute to wide angles, loosely to closely reticulate,cells 17–28x6–8 μm. Appressoria alternate, about 20%opposite, antrorse, subantrorse to rarely recurved, 12–16 μm long; stalk cells cylindrical to cuneate, 3–7 μmlong; head cells globose, entire, rarely truncate at theapex, 9–11x10–12 μm. Phialides mixed with appressoria,alternate to opposite, ampulliform, 14–21x8–10 μm.Mycelial setae scattered to grouped around perithecia,simple, straight, obtuse, dentate to cristate at the apex,up to 441μm long. Perithecia scattered to looselygrouped, globose, up to 140μm in diameter; ascosporesoblong to cylindrical, 4-septate, slightly constricted atthe septa, 33–36x11–13 μm.Materials examined: 14.xii.2003, Champatty, onleaves <strong>of</strong> Flemingiasp.

Hyphaestraight to substraight, branching opposite to alternateat wide angles, loosely reticulate, cells 21–25x6–8µm. Appressoria alternate, straight to curved, mostlyantrorse, 15–25 µm long; stalk cells cuneate, 3–9.5µm long; head cells ovate, globose, cylindrical, entireto slightly angular, 12–18.5x12–15.5 µm. Phialidesnumerous, mixed with appressoria, alternate toopposite, conoid to ampulliform, 18–25x9–12.5 µm.Mycelial setae numerous, simple, straight, acute at theapex, up to 800µm long. Perithecia scattered, verrucose,up to 155µm in diam.; ascospores obovoidal, 4-septate,slightly constricted at the septa, very rarely middle cellslarger, 46–50x12–22 µm.Material examined: 29.vii.2008 on leaves <strong>of</strong> Gardneriaovata Wall.
