Foliicolous fungi <strong>of</strong> Silent ValleyMaterial examined: 2.vii.2008on leaves <strong>of</strong> 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 <strong>of</strong>Triumfetta sp.
