vellerea HDAC phosphorylation has been wrongly placed within the genus Myceliophthora. The ITS1 region of M. vellerea

was highly similar to Ctenomyces serratus (661 of 678 nucleotides identical), suggesting that this species should be placed in the genus Ctenomyces. Fig. 1 Parsimonious consensus tree of the analysed ITS1 region of Myceliophthora sp. and Corynascus sp. (134 of the 389 nucleotides were parsimony informative). The percentage of replicate trees, in which the associated taxa clustered together in the bootstrap test (1000 replicates), are shown next to the branches. All positions containing gaps and missing data were eliminated from the dataset Fig. 2 Parsimonious consensus tree of the analysed elongation factor EF1A gene sequences of Myceliophthora sp. and Akt signaling pathway Corynascus sp. (136 of the 654 nucleotides were parsimony informative). The percentage of replicate trees, in which the associated taxa clustered together in the bootstrap test (1000 replicates), are shown next to the branches. All positions containing gaps and missing data were eliminated from the dataset Fig. 3 Parsimonious consensus tree of the analysed partial RPB2 gene sequences of Myceliophthora sp. and Corynascus sp. (257 of the 611 nucleotides were parsimony informative). The percentage of replicate trees, in which the associated taxa clustered together in the bootstrap test (1000 replicates), are shown next to the branches. All positions containing gaps

and missing data were eliminated from the dataset The C. sepedonium isolates and related Corynascus species clustered together in all phylogenies. Only 1 of 456 nucleotides of the ITS1 sequences within this Corynascus

cluster was found to be parsimony informative. The phylogenies of all three loci showed that M. lutea was the closest related species to C. sepedonium and related Corynascus species. Their close relation was represented by the ITS1 sequences of C. sepedonium and M. lutea, where only three nucleotides were parsimony informative. The isolates of the thermophilic species M. hinnulea and M. thermophila were closely related in all phylogenies. The ITS1 sequences of M. hinnulea and M. thermophila had 12 of 456 parsimony informative nucleotides. Both species clustered with the thermophilic species C. thermophilus in the trees of ITS1 and RPB2. Thirty-two those of 456 nucleotides of the ITS1 sequences within this cluster of the three thermophilic fungi were found to be parsimony informative. However, in the EF1A tree, C. thermophilus clustered separately from all other Corynascus and Myceliophthora isolates. Genetic diversity within the thermophilic Myceliophthora thermophila The 11 isolates listed as M. thermophila consistently clustered in two groups at all phylogenies (Figs. 1, 2 and 3). This variation between the isolates is also reflected by the relatively high amount of informative sites at the three loci (e.g. 12 informative sites of 456 nucleotides of the ITS1 loci; 2.6%).
