Foliicolous fungi <strong>of</strong> Silent ValleyHosagoudar & Rijudiameter, confluent. Hyphae straight to substraight,outer surface tubercled to crenulated, branchingalternate, opposite to irregular at acute to wide angles,loosely to closely reticulate, cells 32–40x7–9 μm.Appressoria scattered, alternate, unilateral, globose,oval, broad based, unicellular, entire, crenulated torarely sublobate, 12–18x14–16 μm. Questieriella type<strong>of</strong> conidia were few, fusiform, curved, 3-septate, centralcells darker, distal cells paler, attenuated towardsthe tip and acute to obtusely rounded at the apices,80–93x9–10 μm. Thyriothecia scattered to connate,dimidiate, orbicular, up to 150μm in diameter, spreadingmarginally, dehisce stellately and dissolve at the centre;asci many, cylindrical, octosporous, 100–120x30–35 μm,sessile; ascospores biseriate, 1–septate, brownish, uppercell smaller and globose, lower cell oval and slightlyattenuated, 30–37x15–17 μm, wall smooth.Materials examined: 03.iii.2009, on leaves <strong>of</strong> Theasinensis (Theaceae) Silent Vally, Shaji et al.

Hyphae substraight to undulating, branchingopposite to alternate at acute to wide angles, looselyto closely reticulate, cells 11–26x4–7 μm. Appressoriaalternate, unilateral, globose, mammiform, entire,6–9x8–11 μm. Conidia <strong>of</strong> Questieriella type were few,scattered, attached directly to the hyphae, curved,3-septate, slightly constricted at the septa, taper towardsboth ends, 28–37x8–11 μm. Sarcinella conidiophoresproduced lateral to the hyphae, single, straight, flexuous,macronematous, mononematous, 0–3 septate, 20–31x4–6 μm; conidiogenous cells terminal, monoblastic,integrated, cylindrical. Sarcinella conidia blastic,terminal, mostly sessile, solitary, dry, ovate to globose,sarciniform, 2–8 celled, constricted at the septa, 17–40μm in diameter, wall smooth. Thyriothecia scattered,globose, orbicular, peridial cells initially radiating, latercentral portion dissolved by exposing the asci, up to66μm in diameter, marginal cells radiating; asci 1–2 perthyriothecia, globose, 4–6 spored bitunicate, 17–26 μmin diameter; ascospores cylindrical, oblong, uniseptate,constricted at the septum, 17–22x6–9 μm, remainhyaline for some time but turn brown at maturity.Materials examined: Silent Valley, on leaves <strong>of</strong>Lagerstroemia microcarpa Wight (Lytheraceae),5.viii.2008, P.P.
