Abstract
Hymenoscyphus pseudoalbidus is the causal agent of ash (Fraxinus excelsior) dieback in Europe. It was recently separated from the European H. albidus based on molecular analyses, while morphologically scarcely distinguishable. Hymenoscyphus albidus was reported under the nomenclatural synonym Lambertella albida on petioles of Fraxinus mandshurica in Japan. The present study reconsidered the taxonomy of L. albida in Japan. Based on a three loci (ITS-5.8S rDNA region, calmodulin gene and translation elongation factor 1-? gene) phylogenetic analysis, Japanese L. albida was found to be conspecific with H. pseudoalbidus, but showed higher genetic variability compared to European isolates. The presence of croziers at the ascus base of both European and Japanese H. pseudoalbidus was found to be a clear distinguishing character to separate this species from H. albidus, which consistently lacks croziers. Our phylogenetic analysis of combined dataset (ITS and LSU-D1/D2) also suggests that the genus Hymenoscyphus is more appropriate than Lambertella to accommodate H. pseudoalbidus, and the Hymenoscyphus clade includes members with two major characters (presence of substratal stroma and brown ascospores) which have currently been used to circumscribe the genus Lambertella. Hence, the generic delimitation of Lambertella requires redefinition.
