Pullospora
Pullospora Faurel & Schotter, Revue Mycol., Paris 29(4): 280 (1965) [1964]
Facesoffungi number: FoF 07554
Ascomycota, genera incertae sedis
Coprophilous. Sexual morph: undetermined. Asexual morph: Conidiomata brown to dark brown, pycnidial, solitary to gregarious, immersed to semi-immersed, ellipsoidal, globose to subglobose or irregular, unilocular, glabrous, thick-walled, ostiolate. Ostiole single, cylindrical, centrally located. Conidiomatal wall composed of thick-walled, dark brown to brown cells of textura angularis. Conidiophores formed from the inner wall layer of conidiomata, hyaline, cylindrical to subcylindrical, straight or slightly curved, branched, septate, invested in mucus. Conidiogenous cells hyaline, enteroblastic, annellidic, subcylindrical to lageniform, integrated or terminal, indeterminate smooth-walled, with percurrent proliferations. Conidia hyaline, cylindrical to subcylindrical, aseptate, thick- and smooth-walled, bearing a primary eccentric basal appendage and 2–4 unbranched, tubular, filiform, subpolar appendages.
Type species: Pullospora tetrachaeta Faurel & Schotter, Revue Mycol., Paris 29(4): 280 (1965) [1964]
Notes: Pullospora species are coprophilous on rodent and jackal dung. Nag Raj (1993) added a second species P. macrospora Nag Raj. The genus is characterized by pycnidial conidiomata, subcylindrical to lageniform, discrete or integrated conidiogenous cells and unicellular, subcylindrical conidia bearing a primary centric basal appendage and 2–4 unbranched, secondary subpolar appendages. No sexual morph has been linked to this genus and no molecular data is available (Nag Raj 1993).
Distribution: France, USA.
