Acrogenospora M.B. Ellis, Dematiaceous Hyphomycetes (Kew): 114 (1971).
MycoBank number: MB 7036; Index Fungorum number: IF 7036; Facesoffungi number: FoF 08065; 13 morhological species (Species Fungorum 2020), 3 species with molecular data.
Type species: Acrogenospora sphaerocephala (Berk. & Broome) M.B. Ellis.
Notes: Acrogenospora altissima was presumed to be the asexual morph of Farlowiella australis Dennis on host surfaces (Ellis 1972) while A. megalospora and F. carmichaeliana were linked by cultural studies (Mason 1941). Molecular data support the synonymy of Acrogenospora and Farlowiella (Jayasiri et al. 2018; Hyde et al. 2019). Nomenclaturally, Acrogenospora was protected over Farlowiella (Rossman et al. 2015). Acrogenospora was monographed by Goh et al. (1998b). The genus is similar to Monotosporella in having macronematous, mononematous conidiophores, monoblastic conidiogenous cells and brown, sphaerical, obovoid to ellipsoidal conidia. However, Acrogenospora has unicellular conidia, while Monotosporella has septate conidia. With little available sequence data, two strains of Monotosporella clustered in Melanommataceae (Dothideomycetes) and Pleurotheciales (Sordariomycetes), respectively (Schoch et al. 2009a; Yang et al. 2019), which are phylogenetically distinct from Acrogenospora.
