Two acrasid cellular slime molds. Guttulinopsis vulgaris and G. nivea , are compared at the ultrastructural level. The amoebae of the two species are indistinguishable except for the presence of intranuclear fibers in G. vulgaris . Both species share some unusual features, including: plate‐like cristae in the mitochondria, production of microbody‐like organelles in the perinuclear space, spores with thin bilaminar walls, and stalks containing microfilaments bound in striated bundles. These and other observations are discussed with regard to the development of the sorocarps and the relationship of the genus to other members of the Acrasida.
