Fig. 3. Consensus tree from the Bayesian phylogenetic analysis, using the internal transcribed spacer (ITS) and second largest subunit of RNA polymerase II (RPB2) reference sequences of nectriaceous fungi published by Gräfenhan et al. [1] and including the strains of the Belgian fungal culture collection BCCM/IHEM used in this study (i.e., IHEM 2040, IHEM 2989, IHEM 5322, IHEM 2105, IHEM 2413, and IHEM 2440). Posterior probabilities (%) are represented at the nodes of the tree. An Acremonium sp. strain was chosen as outgroup. We can distinguish the Fusarium and Fusarium-like clade as defined by Gräfenhan et al. [1], being separated from each other by a large number of species from different genera. The Fusarium sensu Gräfenhan et al. [1] clade in our tree is not monophyletic and the aberrant taxa, for which the genus Bisifusarium was installed by Lombard et al. [3], are indicated by a dashed line. Our six strains with presumed Fusarium-like identities are all embedded in the Fusarium-like clade, for which the different genera, as defined by Gräfenhan et al. [1], are shown.
