Fig. 1. A phylogenetic tree based on the maximum likelihood method analysis of the internal transcribed spacer rDNA region for Acremonium variecolor CNUFC-1YSRS2-4-1, A. variecolor CNUFC-1YSRS2-4-2, A. persicinum CNUFC-GSNPF3-1-1, and A. persicinum CNUFC-GSNPF3-1-2. Acremonium butyri served as an outgroup. Numbers at the nodes indicate the bootstrap values (> 50%) from 1,000 replications. The scale bar indicates the number of substitutions per position. The thick colored clade lines with the asterisk (^*) were constructed by means of a phylogenetic system described by Summerbell et al. [12], whereas the clade lines marked with the asterisk (^**) are suggested by the present authors.
