Sequence alignments for Bullatosporium taxicola - FUSE - Bullatosporium taxicola, a new genus and species in Mytilinidiaceae (Pleosporomycetidae,Dothideomycetes) from western Norway; doi: 10.3114/fuse.2024.14.13

The new genus and species Bullatosporium taxicola are described from dead wood of Taxus baccata in western Norway. Despite some morphological resemblance with Hysteriaceae, including low ascomata with a thick carbonized peridium and mainly five-septate ascospores, multigene analysis of the five molecular markers SSU, ITS, LSU, TEF1-α and RPB2 revealed an affinity to Mytilinidiaceae. The new species formed a strongly supported sister clade to the remaining strains of Mytilinidiaceae. Dichotomous keys to genera of Mytilinidiaceae and to hysterioid species with phragmospores in Fennoscandia are provided to aid identification.
