Figure 1. a and b One of the most parsimonius trees from the phylogenetic analysis based on sequences of a concatenated data set from four nuclear genes (ITS, LSU, β-tubulin and Tef-1α). Bootstrap, Bayes, and ML values are indicated for the major clades, thick lines indicate support of at least 50 %, 0.95, 50 %, respectively. Major and minor clades discussed in the text are indicated with scale bars and named.
