Type species – Xylomelasma sordida Réblová
Notes – Xylomelasma was introduced and delimited from the closely related genus Ceratostomella by Réblová (2006), with two new species, X. novae-zelandiae and X. sordida, both occurring on decaying wood. The third wood-inhabiting species, X. shoalensis, was described in Hernández-Restrepo et al. (2016c). Xylomelasma moderata was transferred to Calyptosphaeria subdenudata in the Xenospadicoidaceae (Réblová et al. 2018).
