Rhodesiopsis
Rhodesiopsis B. Sutton & R. Campb., Nova Hedwigia 30: 289 (1979) [1978]
Facesoffungi number: FoF 07578
Ascomycota, genera incertae sedis
Saprobic on leaves of host plant. Sexual morph: undetermined. Asexual morph: Conidiomata orange-yellow, acervular, scattered to gregarious, initially immersed, becoming erumpent, circular to oval or irregular in outline, unilocular, glabrous, gelatinous, dehiscing by an irregular split in the overlying host tissue. Conidiomatal wall composed of thick-walled, brown to hyaline cells of textura angularis in the basal part. Conidiophores arising from the inner wall layer of basal stroma, hyaline, cylindrical to subcylindrical, branched, septate, smooth-walled, invested in mucus. Conidiogenous cells hyaline, enteroblastic, annellidic, clavate to subcylindrical, integrated, indeterminate, smooth-walled, with percurrent proliferation. Conidia hyaline, ellipsoid to fusiform, with an obtuse or acute apex and a narrow and truncate base, unicellular, thick- and smooth-walled, guttulate, bearing a infundibuliform, flame-like or irregular, mucoid appendage at one end or both ends.
Type species: Rhodesiopsis gelatinosa B. Sutton & R. Campb., Nova Hedwigia 30: 290 (1979) [1978]
Notes: Rhodesiopsis is a monotypic genus. The ellipsoid to fusiform conidia with mucoid, apical appendage can be confused with those of Allantophomopsiella, Allantophomopsis and Zelandiocoela. However, Rhodesiopsis can be separated from these genera by its acervular conidiomata and annelidic conidiogenous cells with up to 7 annellations (Nag Raj 1993). There is no molecular data for Rhodesiopsis. Therefore, new collections are needed to epitypify the genus and to place it in a natural classification.
Distribution: UK.
