Monodia minor

Monodia minor Nag Raj, Coelomycetous Anamorphs with Appendage-bearing Conidia: 526 (1993)

Facesoffungi number: FoF 07454

 

Coprophilous. Sexual morph: undetermined. Asexual morph: Conidiomata 50–160 diam., 50–200 µm high, pale brown to brown with black tip on YPSS agar, pycnidial, scattered to gregarious, immersed to semi-immersed, with globose to subglobose venter, unilocular, glabrous, thick-walled, ostiolate. Ostiole 25–60 × 25–50 µm, circular or oval, with a subcylindrical or irregular neck, dark brown to almost black neck covered by variously curved setae. Conidiomatal wall 10–20 µm thick, composed of thick-walled, dark brown to hyaline cells of textura angularis. Conidiophores arising from the innermost wall layers of conidiomata, hyaline, cylindrical to subcylindrical, branched and broader at the base or above, septate, often constricted at septum, smooth-walled, invested in mucus. Conidiogenous cells hyaline, subcylindrical, integrated, indeterminate, terminal or lateral, smooth-walled. Conidia 8–10 × 2.5–4 µm ( = 9 × 3 µm; n = 30), hyaline, ellipsoid to fusiform or occasionally cylindrical, with obtuse apex, and slightly truncate base, unicellular, guttulate, bearing filiform, tubular, unbranched, flexuous appendages at each end; apical appendages 10–30 µm long, mostly 2, arising from lateral part of upper half, basal appendages 5–25 µm long, 1–3, one centrally located, other two arising from lateral part.

 

Material examined: Australia, New South Wales, dried cultures on YPSS agar (28 January 1982–19 February 1982) isolated from dung of Trichosurus vulpecula (brush tail possum), August 1981, A. Bell (DAOM 215298, type).
