Arthrinium Kunze, Mykologische Hefte (Leipzig) 1: 9 (1817)
MycoBank number: MB 7214; Index Fungorum number: IF 7214; Facesoffungi number: FoF 01781; 73 morphological species (Kirk et al. 200, Index Fungorum 2020), 57 species with sequence data.
Type species – Arthrinium caricicola Kunze & J.C. Schmidt
Notes – Crous & Groenewald (2013) showed that Apiospora is the sexual morph of Arthrinium. Crous & Groenewald (2013) placed the younger sexual typified name, i.e. Apiospora under the older asexual typified name. This adoption was followed in subsequent publications by Dai et al. (2016), Maharachchikumbura et al. (2016b) and Wijayawardene et al. (2016b). Molecular data has proved that Arthrinium is a speciose genus (Dai et al. 2017, Wang et al. 2018, Pintos et al. 2019). We introduce a new holomorph species, Arthrinium neogarethjonesii from bamboo.
