Group F

Major morphological characters of protostelids and protostelid-like ameboid protoctists. Stages not drawn to scale because morphology, not size, is important. Modified from: F.W. Spiegel "Phylum Plasmodial Slime Molds Class Protostelida" in Handbook of Protoctista Group Vb: F1-3, sporocarps of "Eichinostelium bisporum in which sheath shows varying degrees of hydration, spores deciduous, punctate; F4, mastigote cell of "E." bisporum; F5, ameba of "E." bisporum.
