Bullatosporium taxicola, a new genus and species in Mytilinidiaceae (Pleosporomycetidae, Dothideomycetes) from western Norway

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 mole...

Description
Summary: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.
