Also included in the analysis were H. vesicula (CBS 152.96) and H. tartarea (CBS 208.95).
Sequences were aligned using MAFFT (Katoh et al. 2005), v6(Katoh & Toh 2008a) using the Q-INS-i option (Katoh & Toh 2008b). Afterwards sequences were concatenated for phylogenetic inference. To ensure reproducibility and to avoid subjective biases, no manual editing except for the removal of leading and trailing gaps was done. Minimum evolution trees were computed using MEGA v4.0 phylogenetic analysis software (Tamura et al.2007), with factory settings, except for using the Tamura-Neimodel of nucleotide substitution
