Foliicolous fungi <strong>of</strong> Silent ValleyHosagoudar & Rijubrown, uniseptate, constricted at the septum, 27–30x13–15 µm , wall smooth.Material examined: 02.viii.2008 on leaves <strong>of</strong>Rhodomyrtustomentosa (Ait.) Hassk. (Myrtaceae),Walakkad, Sispara, Jacob Thomas et al. HCIO 49037,49038, TBGT 3291, 3292.Asterina sarcandrae Hosagoudar & Kamar. inHosagoudar, Zoos’ Print J. 21: 2305, 2006 (Fig. 97).Colonies hypophyllous, very thin, up to 5mm indiameter. Hyphae flexuous, branching irregular at acuteto wide angles, form a circularly angular and irregularnet, cells 16–21x4–7 µm. Appressoria scattered,alternate to irregular, two celled, antrorse, retrorse,spreading, straight to curved, 12–32 µm long; stalk cellscylindrical to cuneate, 3–7 µm long; head cells ovate,oblong, mostly curved, hamate, twisted, rarely straight,entire, angular to rarely sublobate, 10–26x6–10 µm.Thyriothecia scattered, orbicular, stellately dehisced atthe centre, up to 104µm in diameter, margin crenate;asci few, globose, octosporous, up to 30µm in diameter;ascospores conglobate, uniseptate, strongly constrictedbad10µm8µm8µm10µm7µmFigure 101.
