The new genus Barbatosphaeria is described for a perithecial ascomycete known as Calosphaeria barbirostris occurring on decayed wood of deciduous trees under the periderm. The fungus produces nonstromatic perithecia with hyaline, 1-septate ascospores formed in unitunicate, nonamyloid asci. Anamorphs produced in vitro belong to Sporothrix and Ramichloridium with holoblastic-denticulate conidiogenesis; conidiophores of the two types were formed in succession during the development of the colony. Phylogenetic analyses of nuLSU rDNA sequences indicate that this fungus is distinct from morphologically similar Lentomitella, tentatively placed in the Trichosphaeriales. It groups with freshwater Aquaticola and Cataractispora and terrestrial Cryptadelphia in maximum parsimony analysis; the same grouping but without Cryptadelphia was inferred from Bayesian analysis. Cultivation, morphology and phylogenetic studies of the nuLSU rDNA support the erection of a new genus for C. barbirostris.
