摘要

Phylogenetic and morphological analyses suggest that Biscogniauxia repanda, typified on the basis of a specimen from Europe, differs from the North American B. pezizoides, although the latter has been synonymized under B. repanda shortly after it was newly described in 1889. The here provided evidence is based on ITS sequences and morphological characters of the ascocarp. As a consequence, B. pezizoides is resurrected and both species are re-described. On the basis of earlier studies by others, it is inferred that B. repanda occurs mainly in Europe and Eastern Asia on Sorbus aucuparia and B. pezizoides mainly in North America and Eastern Asia on Ulmus spp. and Acer sp.
