Index Fungorum number: IF 9305; 23 morphological species (Species Fungorum 2020), 11 species with sequence data.
Saprobic on deciduous hosts. Asexual morph: Conidiomata synnematal, indeterminate, scattered, erect, dark brown to black, composed of compact conidiophores adpressed parallel to each other. Conidiophores synnematous, macronematous, brown to dark brown, smooth. Synnemata erect, dark brown to black, velvety, smooth, comprising compact conidiophores adpressed parallel to each other, with flared conidiogenous cells in the above half. Conidiogenous cells polyblastic, terminal and intercalary, usually distinct, rarely integrated, recurved, smooth, denticulate, subhyaline to pale brown, sympodial, each comprising one to several denticulate conidiogenous loci. Conidia ellipsoidal to obovoidal or cylindric-ovate, straight, guttulate, smooth-walled. Sexual morph: Ascomata immersed to superficial, globose to elongate globose, with a long neck. Paraphyses abundant, filamentous, branched, septate, smooth. Asci 8-spored, unitunicate, cylindrical, thin-walled, with a small refractive apical apparatus, smooth-walled. Ascospores filiform, guttulate, tapered at each end, septate, hyaline, smooth-walled (Luo et al. 2019).
Type species: Phaeoisaria bambusae Höhn., Sber. Akad. Wiss. Wien, Math.-naturw. Kl., Abt. 1 118: 329 (1909)
Notes: Höhnel (1909) introduced Phaeoisaria for a collection on Gigantochloa sp. (Bambusae). Phaeoisaria is characterized by indeterminate synnemata with septate or aseptate ellipsoidal, obovoidal, fusiform-cylindrical or falcate conidia (Hyde et al. 2020).
