Group D
Description
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 IV: D1, sporocarp of Cavostelium
apophysatum, spore nondeciduous, puntuately marked; D2, extended
mastigote cell of C. apophysatum; D3, "raspberry" mastigote cell of
C. apophysatum; D4, ameba typical of Group IV on dry surface;
D5, ameba in water; D6, sporocarp of Schizoplasmodiopsis
ameboidea, spore nondeciduous, faintly punctate; D7, sporocarp of
Schizoplasmodiopsis micropunctata, spore nondeciduous, minutely punctate;
D8, sporocarp of Schizoplasmodiopsis reticulata, spore nondeciduous
reticulate; D9, sporocarp of Schizoplasmodiopsis vulgare, spore
nondeciduous, faintly punctate, stalk coarse; D10, sporocarp of
Schizoplasmodiopsis pseudoendospora, spore nondeciduous, faintly punctate;
D11, finely reticulate plasmodium of S. pseudoendospora.
