Fig. 1 Phylograms inferred from maximum likelihood analyses of ITS sequences of Auricularia. Herbarium codes or collection codes are followed by species names. Cultivated strains are in bold. Bootstrap support values >60% are displayed above each node. The tree is rooted with Eichleriella deglubens (FO12006), Exidia recisa (MW315), and Exidiopsis grisea (RoKi162).
