ThreatenedTaxa 3(3): 1618, 2011 (Fig. 67).Colonies amphigenous, mostly hypophyllous, dense,velvety, up to 4mm diam., confluent. Hyphae flexuousto undulate, branching opposite to alternate at acute towide angles, loosely to closely reticulate, cells 15–25x5–10 μm. Appressoria alternate, opposite to unilateral,antrorse to subantrorse, rarely retrorse, 17–28 μm long;stalk cells cylindrical to cuneate, 5–8 μm long; headcells oblong to cylindrical, straight to flexuously curved,entire, 10–20x5–8 μm. Phialides mixed with appressoria,alternate, opposite to unilateral, ampulliform, 20–30x6–8 μm. Mycelial setae straight to curved, scattered, acuteat the tip, up to 720μm long; Perithecia scattered in thecolonies, up to 240μm in diam.; ascospores obovoidal,4-septate, constricted at the septa, 50–55x20–23 μm.Material examined: 01.vii.2008 on leaves ofStrombosia sp. (Olacaceae), Cheriya Walakkad, M.C. Rijuet al. TBGT 4515 (holotype), HCIO 50598 (isotype).Meliola wendlandiae Hosag. in Hosagoudar & Goos,Mycotaxon 37: 251, 1990; Hosagoudar, Meliolales ofIndia, p. 340, 1996 (Fig. 68).Colonies amphigenous, mostly hypophyllous,subdense, subvelvety, up to 4mm in diameter,confluent. Hyphae sinuous to crooked, branchingopposite to irregular at acute angles, loosely to closelyreticulate, cells 18–32x6–10 µm. Appressoria alternate,spreading, antrorse, 20–30 µm long; stalk cells cuneateto cylindrical, 6–12 µm long; head cells ovate, narrowtowards apex, slightly angular, entire, 15–18x12–14 µm.Phialides borne on a separate mycelial branch, alternateto opposite, ampulliform, 14–20x8–10 µm. Mycelialsetae few, grouped around perithecia, simple, straight,acute to subacute at apex, up to 344µm long. Peritheciascattered, verrucose, up to 168µm in diam.; ascosporesobovoidal, 4-septate, constricted, 36–46x12–18 µm.Material examined: 13.xii.2003 on leaves of Wendlandiathyrsoidea (Schultes) Steud (Rubiaceae), Sairandhri, V.B.Hosagoudar et al.
