Brachiosphaera
Brachiosphaera Nawawi, in Descals et al., Trans. Br. mycol. Soc. 67: 213 (1976).
Index Fungorum number: IF 7438; Facesoffungi number: FoF 07685, 2 morphological species (Species Fungorum 2022), 2 species with molecular data.
Hyphomyceteous. Sexual morph: Unknown. Asexual morph: Mycelium composed of brown, septate, branched hyphae. Conidiophores simple or rarely ramose, macronematous or semi-macronematous, erect or flexible, septate. Conidiogenous terminal cells, holoblastic, sympodial or rarely running around. Conidia spherical and 4-7 radiating, septate, provided with simultaneous arms (adapted from Descals et al. 1976).
Type species: Brachiosphaera tropicalis Nawawi
Notes: Brachiosphaera is characterised by brown, septate, branched hyphae, macronematous or semi-macronematous conidiophores, holoblastic, sympodial conidiogenous terminal cells and spherical conidia with 4−7 radiating arms. Brachiosphaera resembles Asctinospora in conidial morphology but can be differentiated based on the method of conidial production. Molecular markers available for Brachiosphaera include ITS, LSU, SSU and TEF-1.
