Type species.

Melanconis stilbostoma (Fr.) Tul. & C. Tul., Select. fung. carpol. (Paris) 2: 115 (1863)

Notes.

The type genus Melanconis was established by Tulasne and Tulasne (1863) based on Sphaeria stilbostoma Fr. This genus is characterised by circularly arranged perithecia immersed in well developed to reduced entostromata with a concolourous central column and ostioles erumpent through a light-coloured ectostromatic disc with hyaline, one-septate ascospores; acervuli with light-coloured central column producing brown to olive-brown, fusiform to pyriform alpha conidia and hyaline, cylindrical or allantoid beta conidia ( Barr 1978; Castlebury et al. 2002; Voglmayr et al. 2012; Fan et al. 2016). Melanconis has approximately 105 species epithets recorded in Index Fungorum (2018), whereas Rossman et al. (2007) suggested that many of the species previously residing in Melanconis may belong somewhere else. Fan et al. (2016) provided an account on this genus including five species ( Melanconis alni , Ms. betulae , Ms. marginalis , Ms. itoana and the type species Ms. stilbostoma ), which were restricted to hosts in Betulaceae .
