Citation when using this data: Jing Yang et al. 2023 – Fungalpedia. 

Index Fungorum, Faceoffungi, MycoBank, GenBank, Fig 1.

Classification: Dactylosporaceae, Sclerococcales, Sclerococcomycetidae, Eurotiomycetes, Pezizomycotina, Ascomycota, Fungi.

Notes: Réblová et al. (2020a) established Gamsomyces to accommodate two asexual fungi with sporodochial or synnematous conidiomata, semi-macronematous or macronematous, fasciculate conidiophores, monoblastic conidiogenous cells and multi-septate, narrowly fusiform conidia with a mucilaginous cap at the apex. Dong et al. (2020a), at the same time, introduced a new genus Pseudobactrodesmium which matches the generic concept of Gamsomyces. Multigene phylogenetic analysis of the combined dataset revealed that both genera represent the same genus (Jing Yang et al. 2023). We therefore recommend Gamsomyces for use following the priority consideration.

Type species: Gamsomyces aquaticus (W. Dong, H. Zhang & K.D. Hyde) J. Yang & K.D. Hyde.

Other accepted species: Species Fungorum – search Gamsomyces.
