Foliicolous fungi of Silent ValleyMaterial examined: 2.vii.2008on leaves of Toddaliaasiatica (L.) Lam. (Rutaceae), Cheriavalakkad, M.C. RijuHCIO 50596, TBGT 4513.The genus IrenopsisIrenopsis triumfettae (Stev.) Hansf. & Deight. var.indica Hosag. & T.K. Abraham, J. Mycopathol. Res. 36:98, 1998 (Fig. 21).Colonies amphigenous, dense, up to 1mm indiameter, confluent. Hyphae straight to flexuous,branching irregular at acute angles, loosely reticulate,cells 24–29x7–9 μm. Appressoria alternate, antrorseto subantrorse, 17–22 μm long; stalk cells cylindrical tocuneate 4–8 μm long; head cells globose to slightly ovate,entire, 12–15x12–15 μm. Phialides numerous mixedwith appressoria, alternate to opposite, ampulliform,14–22x7–9 μm. Perithecia scattered, globose, verrucose,up to 160μm in diameter; Perithecial setae 6–8, simple,straight to slightly curved, tortuous to beaded andgranulose towards the apex, obtuse at the apex, upto 140μm long, ascospores oblong, 4-septate, slightlyconstricted at the septa, 36–46x12–17 μm.Hosagoudar & RijuMaterial examined: 13.xii.2003 on leaves ofTriumfetta sp. (Tiliaceae), Sairandhri, V.B. Hosagoudar etal. HCIO 46231, TBGT 1643.The genus MeliolaMeliola affinis Syd. var. indica Hosag., Nova Hedwigia47: 538, 1988; Hosagoudar, Meliolales of India 2: 124,1996 (Fig. 22).Colonies hypophyllous, very thin, up to 5mm indiameter, confluent. Hyphae substraight to undulate,branching opposite to irregular at wide angles, looselyreticulate, cells 21–31x6–8 µm. Appressoria alternate,rather distantly arranged, straight to curved, mostlyantrorse, 15–22 µm long; stalk cells cuneate 9–12.5µm;head cells ovate, pointed towards the apex with broadlyrounded ends, entire, 9–12.5x6–9.5 µm. Phialides mixedwith appressoria, opposite to alternate, ampulliform, 21–25x6–9.5 µm. Mycelial setae grouped around perithecia,straight, simple, acute, up to 630µm long. Peritheciascattered, verrucose, up to 120µm in diam.; ascosporesobovoidal, 4-septate, constricted, 37–40x15–18 µm.Material examined: 2.ii.2009 on leaves of Memecylonaccdb10µm7µmabdFigure 22.
