Figure 2.

Two-gene multilocus phylogenetic tree constructed from the combination of ITS and LSU ribosomal sequences of 44 strains realized with Neighbour-Joining methods. Numbers indicate bootstrap confidence percentages. Bootstrap values above 70%, calculated from 1000 resampled data sets, are shown. The strains isolated from Florence Cathedral are indicated in bold, in red are identified the strains isolated from SE, and in green are identified the strains isolated from NW. The scale bar indicate the substitution per nucleotide. The accession numbers of sequences retrieved from the database are reported in Table S1; the accession number of the Saccharomyces cerevisiae sequence (outgroup) is GQ458028.
