The monotypic genus Xylochrysis is introduced for a lignicolous perithecial ascomycete that possesses golden yellow ascomata with black glabrous necks, a three-layered ascomatal wall, persistent paraphyses, and cylindrical, long-stipitate unitunicate asci with an inamyloid apical annulus, and hyaline, ellipsoidal, unicellular ascospores. In culture it produces hyaline conidiophores with terminally arranged branches bearing metulae, conidiogenous cells and holoblastic conidia. Phylogenetic analysis of two ribosomal (nc18S and nc28S rDNA) and one protein-coding (RPB2) gene position this species within the Sordariomycetidae but without close ordinal or familial affiliation. Morphological and molecular DNA data support the recognition of this new genus and suggest that Xylochrysis is most closely related to the genera Ceratolenta, Cyanoannulus and Woswasia.
