Notes.

Melanconis 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, fusiform to pyriform alpha conidia and hyaline, cylindrical or allantoid beta conidia ( Voglmayr et al. 2012; Fan et al. 2016 a). All known species of this genus have been reported exclusively on hosts within the family Betulaceae (specifically Alnus and Betula ) ( Fan et al. 2018 b; Jaklitsch and Voglmayr 2020).
