18S rDNA phylogeny of lamproderma and allied genera (Stemonitales, Myxomycetes, Amoebozoa).

The phylogenetic position of the slime-mould genus Lamproderma (Myxomycetes, Amoebozoa) challenges traditional taxonomy: although it displays the typical characters of the order Stemonitales, it appears to be sister to Physarales. This study provides a small subunit (18S or SSU) ribosomal RNA gene-b...
