Maximum-likelihood (ML) phylogenetic tree based on 18 S rRNA gene sequences, showing the position of Monomicrocaryon trimarginalis sp. nov. The new sequence is shown in bold and indicated by an arrow. The numbers at nodes indicate the ML bootstrap values and Bayesian-inference (BI) posterior probability. The estimated BI tree did not recover nodes designated with a dash (-). The scale bar corresponds to two substitutions per 100 nucleotide positions.	Figure 4.
