Foliicolous fungi <strong>of</strong> Silent ValleyHosagoudar & RijuWattakaka sp. (Asclepiacaceae), Silent Valley, P.P. RajeshKumar et al. HCIO 49832, TBGT 3984.The genus EchidnodellaEchidnodella memecyli Hosag. & T.K. Abraham,J. Mycol. Res. 102: 185, 1998; Hosagoudar, C.K. Biju &Abraham, J. Econ. Taxon. Bot. 25: 306, 2001; Hosagoudar,Zoos’ Print J. 18: 1283, 2003; Hosagoudar, Chandraprabha& Agarwal, Asterinales <strong>of</strong> Kerala, p. 194, 2011 (Fig. 105).Colonies hypophyllous, subdense, spreading, up to5mm diameter, widely confluent; Hyphae substraight,flexuous to crooked, branching opposite to irregular atacute to wide angles, loosely reticulate, cells 24–29x2.5–3.5 μm. Appressoria absent. Thyriothecia scattered,rarely connate, ovate, elongate, straight, curved, acutelysinuate to variously branched, 530–635x31–36 μm,longitudinally split at the centre, mostly crenate at themargin and rarely fimbriate, fringed hyphae very small.Asci ovate, clavate, globose, 8-spored, 33–36x19–24μm. Ascospores conglobate, 1-septate, constricted atthe septum, lower cell slightly attenuated and upperrounded, 12–14.5x–4–6 μm, wall smooth.Material examined: 13.ii.2007, on leaves <strong>of</strong>Memecylon sp.

(Image 15)Colonies epiphyllous, dense, crustose, smooth, up to10mm in diameter, <strong>of</strong>ten causeyellow haloes around thecolonies and also yellowing on the corresponding lowersurface <strong>of</strong> the leaves. Hyphae partly superficial and partlyimmersed, superficial hyphae brown, septate, flexuous,irregularly branched at acute to wide angles, cells 12–35x–3–4 μm. External mycelium enters the host throughstomata extended up to palisade tissues. Conidiophoresarise from the external mycelium, mostly deep brownto rarely dark, 0–1septate, erect, <strong>of</strong>ten curved, simple,solitary, smooth, 25–32 μm long; conidiogenous cellsterminal, integrated, monoblastic, determinate; conidiabrown, 0–3 septate, not constricted, straight to curved,cylindrical, obclavate, broadly rounded at the apex,truncate at the base, wall smooth, 20–48x8–10 μm.Thyriothecia scattered to grouped, initially orbicular, laterelliptic to elongated, simple, straight, curved, <strong>of</strong>ten X orY shaped, astomatous, dehisce vertically at the centre,Image 16.
