Ascomycota, genera incertae sedis


Saprobic on the host plant in terrestrial habitat. Sexual morph: undetermined. Asexual morph: Conidiomata blackish brown, stromatic, pycnidial, solitary, semi-immersed to erumpent, hemispherical to pulvinate, unilocular, glabrous, pushing up a flap of epidermis. Ostiole papillate, centrally located. Conidiomatal wall composed of thick-walled, dark brown to black, dome-shaped, small cells of textura angularis in the upper and lateral part, becoming thin-walled, pale brown in the base. Conidiophores arising from inner layers of basal stroma, hyaline, filiform, cylindrical or irregular, branched, with many septa delimiting small cells, aggregated into synnemata within the locule. Conidiogenous cells hyaline, enteroblastic, phialidic, doliiform, integrated, determinate, smooth-walled, with lateral apertures immediately below transverse septa. Conidia hyaline, cylindrical with an obtuse apex, and a narrow base, straight or slightly curved, unicellular, smooth-walled, eguttulate (adapted from Sutton 1980).


Type species: Stilbophoma microspora Petr., Bot. Arch. 53: 93 (1942) [1941]


Notes: Stilbophoma is characterized by pycnidial conidiomata with thick-walled, blackish brown, sclerotized upper and lateral wall, and stilboid aggregations of conidiophores, monophialidic, doliiform conidiogenous cells with solitary terminal or lateral apertures, and cylindrical conidia (Sutton and Funk 1975, Sutton 1980). Pragmopycnis shares similar form of conidiomata with Stilbophoma, but the conidiomata of Pragmopycnis are not stipitate, the conidiogenous cells are polyphialidic, and the conidia are fusiform, and/or? allantoid. Sutton (1980) revised Stilbophoma and accepted two species, S. microspore collected on Borassus sp., (Arecaceae) and S. inaequalis (Sacc. & Trotter) B. Sutton collected on Pandanus sp. Neither species has been studied with molecular data. To clarify the taxonomy of Stilbophoma and closely related genera, fresh collections of the type species are needed.


Distribution: India, Congo (Sutton 1980).
