TBGT 5233.The genus DysrhynchisThis genus differs from Balladyna in absence ofappressoria.Dysrhynchis uncinata (Syd.) Arx in Müller & Arx, Beitr.Kryptogamenflora der Schweiz 2: 191, 1962; Hosagoudar,Persoonia 18: 125, 2002. (Fig. 108, Image 18).Ballydyna uncinata Syd., Ann.

Hyphae straight to crooked,branching irregular at acute angles, loosely to closelyreticulate, cells 14–29x2–5 µm. Appressoria absent.Mycelial setae numerous, simple, straight, flexuous,uncinate, subacute to obtuse, up to 120µm long.Hosagoudar & RijuPerithecia slightly stipitate, globose, ovate, ostiolate,33–38 µm in diameter; asci visible in mature perithecia,1–2 in numbers, ovate to globose, octosporous, 28–36µm in diameter; ascospores conglobate, oblong, brown,uniseptate, constricted at the septum, broadly roundedat both ends, 24–29x7–10 µm, wall smooth in young.Materials examined: 30.iii.2009 on the leaves ofOchlandra rheedi (Kunth) Benth. ex Gamble (Gramineae),Neelikal, Silent Valley, M.C. Riju & Gireesh Kumar HCIO51027, TBGT 4944.The genus MeliolinaThis is a black mildew, infect predominantlyMyrtaceae plants, produces thick, spongy colonies onthe lower surface of the leaves.Meliolina pulcherrima (H. Sydow & P. Sydow) H.Sydow & P. Sydow, Ann. Mycol. 12: 553, 1914. (Image19)Colonies hypophyllous, black, thick, 3–5 mm indiam., a pinkish or discoloration occurs below thecolonies and is some times also evident on the uppersurface. Superficial hyphae form a cushion of closelyinterwoven, irregularly branched, brown to darkbrown hyphae, septate, 32–43 μm long and 7–10 μmwide. Phialophores arising as branches of the compactsuperficial hyphae, densely crowded, up to 128μm long,flexuous, simple, or 1 or 2 dichotomously or irregularlybranched clearly differentiated in to stalk and branches,5–7 μm wide, brown towards the base, narrowing slightlya7µmb8µm7µmbcac9µmd8µmFigure 109.
