Xylomelasma Réblová, Mycologia 98(1): 87 (2006)
Index Fungorum number: IF501459; 3 morphological species (Species Fungorum 2020), 2 species with sequence data.
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. (2016). Xylomelasma moderata was transferred to Calyptosphaeria subdenudata in the Xenospadicoidaceae (Réblová et al. 2018).
