Arthrographis G. CochetNotes.The genus Arthrographis was established by Cochet (1939), with A. langeronii G. Cochet as the type species. Due to a lack of a Latin diagnosis, it did not conform to the International Code of Botanical Nomenclature (ICBN), so it was regarded as invalid (Giraldo et al. 2014; Li et al. 2022). Later, based on morphological characteristics, Sigler and Carmichael (1976) introduced Arthrographis kalrae (basionym: Oididendron kalrae R. P. Tewari & Macph.) and A. cuboidea (basionym: Scytalidium cuboideum (Sacc. & Ellis) Sigler & Kang) and validated the genus name (Sigler and Carmichael 1976). The asexual morph of Arthrographis species was characterized by a slow growth rate and by the presence of cylindrical arthroconidia released schizolytically from dendritic conidiophores (Sigler and Carmichael 1976; Giraldo et al. 2014). Based on multi-gene phylogeny and morphological characteristics, four new species, A. chlamydospora A. Giraldo, Deanna A. Sutton, Cano & Madrid, A. curvata A. Giraldo, Gené, Deanna A. Sutton & Cano, A. globosa A. Giraldo, Deanna A. Sutton, Cano & Guarro, and A. longispora A. Giraldo, Deanna A. Sutton, Cano & Guarro, were proposed by Giraldo et al. (2014). Recently, A. grakistii Giraldo López & Hern. - Restr. was reported as a new species by Hernández-Restrepo et al. (2020). Arthrographis multiformispora Xin Li, Y. F. Han & Z. Q. Liang was introduced by Li et al. (2022), while some species were transferred to other genera (Kang et al. 2010; Giraldo et al. 2014). Currently, the genus Arthrographis includes 11 species in Index Fungorum (2025) (published on the Internet at http://www.indexfungorum.org, The Royal Botanic Gardens, Kew. [Retrieved 16 March 2026]).
