Koorchaloma occidentale Nag Raj, Mycotaxon 19: 191 (1984)
Facesoffungi number: FoF 07436
Saprobic on blades of Gramineae. Sexual morph: undetermined. Asexual morph: Conidiomata 80–180 µm diam., 40–70 µm deep (conidiomatal dimension from Nag Raj 1993, excluding the conidial mass), with yellow to brownish yellow crusts, stromatic, shallow-cupulate, mostly solitary, sometimes gregarious or confluent, superficial, appearing as pulvinate, gelatinous, rounded to oval in outline, setose. Conidiomatal wall composed of two types: a) basal wall of textura angularis with hyaline cells; b) excipulum moderately developed, of textura oblita in the outer layers merging with textura intricata in the inner layers. Conidiomatal setae 80–160 μm long, 3–10 μm wide, interspersed throughout the conidioma, brown in the basal part, becoming pale yellow to almost colourless at the apex, subulate with a slightly bulbous base and an acute apex, straight or variously curved, unbranched, septate, with the septa indistinct in the upper part, often showing percurrent growth. Conidiophores hyaline, cylindrical to subcylindrical, branched, septate, invested in mucus. Conidiogenous cells 12–17 × 2–3 μm, hyaline, ampulliform to lageniform or obclavate, with minute collarettes, discrete or sometimes integrated, smooth-walled. Conidia 8–14 × 2–4 ( = 11 × 3) μm, hyaline, fusiform, with an acute apex and a narrow truncate and often apiculate base, aseptate, smooth-walled, guttulate, bearing a mucoid appendage at each end.
