Notes: Pseudobactrodesmium was introduced by Dong et al. (2020a) with P. longisporum (≡ Bactrodesmium longisporum) as the type species. Pseudobactrodesmium aquaticum, P. chiangmaiensis and P. longisporum were included in the genus. Pseudobactrodesmium longisporum was formerly placed in Bactrodesmium (Dothideomycetes genera incertae sedis), but multigene phylogenetic analysis revealed it was unrelated to Bactrodesmium and clustered within Sclerococcales (Eurotiomycetes) (Ellis 1976; Pem et al. 2019b; Dong et al. 2020a; Wijayawardene et al. 2020).
Type species: Pseudobactrodesmium aquaticum W. Dong, H. Zhang & K.D. Hyde, in Dong, Hyde, Doilom, Yu, Bhat, Jeewon, Boonmee, Wang, Nalumpang & Zhang, Frontiers Microbiol. 11(no. 565): 5 (2020).
Other accepted species: Species Fungorum – search Gamsomyces.
