Foliicolous fungi <strong>of</strong> Silent ValleyHosagoudar & Rijud6.6µmbaalternate to opposite, ampulliform, 15–22x6–9.5 µm.Mycelial setae evenly scattered over the colonies,straight, simple, acute to obtuse at the tip, up to 510µmlong. Perithecia scattered, verrucose, up to 175µm indiam.; ascospores obovoidal to cylindrical, 4-septate,slightly constricted, 40–45x12–16 µm.Material examined: 12.xii.2003, on leaves <strong>of</strong>Nephelium sp. (Sapindaceae), Sairandhri, V.B.Hosagoudar et al. HCIO 47717, TBGT 2739.Figure 63.

Res.44: 45, 2006 (Fig. 66).Colonies amphigenous, mostly epiphyllous, dense,crustose to velvety, up to 5mm in diameter, correspondingopposite surface <strong>of</strong> the showed water soaked lesion.Hyphae straight to flexuous, branching mostly oppositeat acute angles, loosely to closely reticulate, cells19–24x–6–8 µm. Appressoria alternate, antrorse toclosely antrorse, 22–26 µm long; stalk cells cylindrical tocuneate, 4–8 µm long; head cells ovate, oblong, broadlyrounded to <strong>of</strong>ten attenuated at the apex, entire, rarelyangular to sublobate, 16–18x12–14 µm. Phialides borneon a separate mycelial branch, alternate to opposite,ampulliform, 16–23x7–9 µm. Mycelial setae few, simple,straight, acute to obtuse at the tip, up to 350µm long.Perithecia loosely grouped at the centre <strong>of</strong> the colonies,up to 175µm in diam.; ascospores oblong to cylindrical,4- septate, constricted at the septa, 40–44x18–20 µm.Materials examined: 12.xii.2003 on leaves <strong>of</strong>Meliaceae member, Sairandhri, near Kunthipuzha, V.B.Hosagoudar et al.
