Description
Summary:Two new species, and , are described on the basis of morphological characters, phylogenetic evidence, host preferences and geographic distributions. A taxonomic key to the known species in China is also provided to facilitate identification. Based on samples from temperate Asia, Europe and North America, the phylogeny of was reconstructed using the internal transcribed spacer (ITS) region, the large subunit (LSU) of the ribosomal DNA and the translation elongation factor 1-α (TEF1).The phylogenetic results showed that contains two monophyletic clades: the /subalpinum clade and the /imperiale clade. The Asian species and are closely related to the North American sp. (labelled as in GenBank) in the /subalpinum clade, whereas and are closely related in the /imperiale clade.
