Arthrocatena

Arthrocatena Egidi & Selbmann, in Crous et al., Fungal Systematics and Evolution 3: 126 (2019).

            Index Fungorum number: IF 829384; Facesoffungi number: FoF 11412, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.

            Saprobic on rock. Sexual morph: Unknown. Asexual morph: Colonies growing slowly, dark, velvety, compact; hyphae torulose to dark brown, branched, developing longitudinal and oblique septa producing arthroconidia by disarticulation. Conidia dark brown, thick-walled, sometimes with a median septum.

 

Type species: Arthrocatena tenebrosa Egidi & Selbmann

 

Notes: Arthrocatena tenebrio was invalidly published. Crous et al. (2019) redefined the genus Arthrocatena and designated A. tenebrosa Egidi & Selbmann as the type species. Arthrocatena is characterised by dark, arthric conidia produced in chains. The systematic position of Arthrocatena is uncertain and is currently placed in Mycosphaerellales genera incertae sedis. Molecular markers available for Arthrocatena are ITS, LSU RPB2, SSU and mtSSU.
