Reassessment of , phylogenetic position of , and sp. nov.

The genus is synonymised with , based on morphological and molecular phylogenetic considerations. Investigations of types and fresh collections revealed that is an earlier name for (syn. ) and is thus combined in . is recognised as a distinct species and transferred to , as well as the recently described . Descriptions and illustrations are provided for and . A recent collection of the North American , the generic type of , was studied with respect to morphology of its sexual morph in fresh condition and of its asexual morph produced in pure culture. Molecular phylogenies based on six loci (ITS and LSU regions of nuc rDNA, , , , and genes) place within , confirming synonymy of with , but remarkably a relationship to European species with green to brown spores (former genus ) receives no support, and its closest relatives remain unclear. is described as a new species from herbarium specimens of collected in the Ukraine. It is characterised by morphology of the sexual morph and by DNA sequence data, which place it within the - clade with high support. This is also supported by its morphology, specifically ascomata partly embedded within a stroma, muriform ascospores not budding within the ascus, becoming yellowish to rosy at maturity.
