Fig. 1. Minimum evolution tree based on the internal transcribed spacer rDNA sequences. Bootstrapping support values of minimum evolution and maximum likelihood methods higher than 60% are given above or below the branches. The species revealed in the present study are shown in blue while the previously known species are shown in red. The scale bar equals the number of nucleotide substitutions per site.

Colonies on potato dextrose agar at top (A, J) and at bottom view (B, K). Colonies on V8 agar at top (C, L, S) and at bottom view (D, M, T), Colonies on corn meal agar at top (E, N, U) and at bottom view (F, O, V). P, Sporangiophore; G~I, Q, W, Sporangium; R, Sporangiospore (scale bars: G = 50 μm, P = 20 μm, H~I, G~R, W = 10 μm).
