Type species – Chloridium viride Link Notes – Chloridium is characterised by mononematous or macronematous conidiophores, monophialidic or polyphialidic conidiogenous cells, with a funnel-shaped collarette and hyaline to brown, eguttulate or guttulate, appendaged or non-appendaged conidia (Link 1809, Wei et al. 2018). Réblová et al. (2016) pointed out that the generic type of Chloridium, C. viride is congeneric with Melanopsammella inaequalis, the type of Melanopsammella (Fernández et al. 2006, Crous et al. 2012). Hughes (1951c) revealed that the generic type of Gonytrichum, G. caesium, is the asexual morph of Melanopsammella inaequalis. By considering the above facts, Réblová et al. (2016) proposed that Gonytrichum and Melanopsammella are synonyms of Chloridium. Hence, the widely used generic name Chloridium was conserved over Gonytrichum and Melanopsammella (Réblová et al. 2016, Wei et al. 2018). Furthermore, Chloridium species seems to be polyphyletic within Chaetosphaeriaceae (Hyde et al. 2020). Currently, 30 species epithets are listed for Chloridium (Wijayawardene et al. 2022, Species Fungorum 2022).
