Pseudorobillarda indica Nag Raj, Morgan-Jones & W.B. Kendr., Can. J. Bot. 50(4): 865 (1972)
Facesoffungi number: FoF 07562
Foliicolous. Sexual morph: undetermined. Asexual morph: Conidiomata 150–300 µm diam., 200–350 µm high, brown to dark brown, pycnidial, solitary to gregarious or confluent, immersed to semi-immersed, oval to rounded, with a short-cylindrical neck in surface view, globose to subglobose, occasionally conical in sectional view, unilocular, glabrous, ostiolate. Ostiole 50–60 × 30–40 µm, single, circular to subcylindrical, centrally or laterally located. Conidiomatal wall 10–30 µm wide, composed of thick-walled, brown to hyaline cells of textura prismatica. Paraphyses 30–60 × 1–2 µm, hyaline, filiform, septate, branched and bulging at base, smooth-walled, mixed with conidiophores. Conidiophores arising from the inner wall layers of conidiomata, hyaline, dolliform to subcylindrical, thick- and smooth-walled, invested in mucus. Conidiogenous cells 6–9 × 3–5 µm, hyaline, enteroblastic, phialidic, cylindrical to ampulliform, swollen at base, indeterminate, discrete or integrated, with marked periclinal thickenings at collarette zone. Conidia 16–24 × 2.4–4 µm ( = 20 × 3 µm; n = 30), hyaline, subcylindrical to fusiform, subacute at apex, blunt and truncate at base, straight or slightly curved, 1-septate, occasionally 3-septate, constricted at the septa, guttulate, thick- and smooth-walled, bearing at one end 3, occasionally 2–4, flexuous, divergent, extracellular appendages (11–23 µm long).
Material examined: India, Bangalore, Rajajinagar, 19 October 1970 to 16 November 1970, T.R. Nag Raj (DAOM 134448, cultured on PDA from type).
