The Physarales are an order of Amoebozoa in the class Myxomycetes. Sturgis is best known for his research into the Myxomycetes (slime molds). His protista were divided into moneres, protoplasts, flagellates, diatoms, myxomycetes, myxocystodes, rhizopods, and sponges. Apogamic development can also occur in nature in various species of myxomycetes. Two species of "Hemitrichia" offer important insights into the evolution of the myxomycetes. At the moment 5584 species of Fungi and Myxomycetes (Protista) have been identified in Finland. Latest phylogenetic data place dictyostelids firmly within supergroup Amoebozoa, along with myxomycetes. Trichiida are endosporous Myxomycetes, meaning their spores are held within an acellular structural wall4.
