Myxogastria (also called Myxomycetes or plasmodial slime‐moulds) are mostly known through their usually conspicuous fruiting bodies. Another unifying trait is the presence of a facultative flagellate stage along with the obligate amoeboid stage. Here we show with two‐gene phylogenies (SSU rRNA and EF‐1alpha genes) that the incertae sedis , non‐flagellate Echinosteliopsis oligospora belongs to the dark‐spore clade (Fuscisporidia) of the Myxogastria. In addition, we confirm that Echinostelium bisporum , firstly described as a protostelid, belongs to the Echinosteliida, which are divided into three major clades and are paraphyletic to the remaining Fuscisporidia.
