Eriksson (1982) introduced the genus Amarenographium to accommodate Camarosporium metableticum whose morphology differed from the definition of Camarosporium. The conidiophores are much longer and branched, with phialidic conidiogenesis with solitary conidia that are provided with a characteristic polar gelatinous appendage. Eriksson (1982) described the morphological similarity between Amarenographium metableticum and Amarenomyces ammophilae and suggested these taxa might be the same biological species. Nag Raj (1993) also considered Amarenomyces as the sexual morph of Amarenographium. However, these genera were not connected by molecular data or culture-based methods, thus Phookamsak et al. (2014) and Wijayawardene et al. (2014) treated Amarenographium and Amarenomyces as distinct genera in Phaeosphaeriaceae. Taylor et al. (2003) described a second species of Amarenographium,
A. sinense from a dead petiole of Trachycarpus fortuneifrom Hubei Province, China. Sequence data is available only for A. solium and A. ammophilae, while the type species of Amarenographium lacks sequence data. However, A. solium did not group within Phaeosphaeriaceae in previous studies by Hodhod et al. (2012), Wijayawardene et al. (2014) and Wanasinghe et al. (2018), hence, Amarenographium was considered as a polyphyletic genus in Pleosporales (Wijayawardene et al. 2014, Wanasinghe et al. 2018). In this study, we introduce the first sexual morph for Amarenographium, which was collected from a marine based habitat.

Type species: Amarenographium metableticum (Trail) O.E. Erikss., Mycotaxon 15: 199 (1982).

Other accepted species: Species Fungorum – search Amarenographium.
