Monographs Details: Anacystis anomala N.L.Gardner
Authority: Gardner, Nathaniel L. 1927. New Myxophyceae from Porto Rico. Mem. New York Bot. Gard. 7: 1-144. pl. 1-23.
Description:Species Description - Colonies very irregular in shape and size, with a tendency to being cuboidal with rounded corners in the earlier stages of development, containing approximately 1000 cells; single, free cells spherical to subspherical, 2.8-3.2 µ diam. with tegument, cuboidal in the colony and 1.3-2.5 µ diam. without wall, arranged quite definitely in rows in the medium-sized colonies, the colonies often becoming much lobed when old; tegument thin, smooth, and hyaline.

Distribution and Ecology - Growing in company with other Myxophyceae on a wall, Juan Martin, Fajardo, no. 732 b, type.


This species is certainly aberrant. It does not conform to any known genus in all of the stages of its life cycle. In the young stages, the colonies, up to 8 cells, resemble a typical species of Cliroococeus. From this time on, the development is not symmetrical. Certain cells cease to divide temporarily or permanently,while others become very active, eventually resulting in a colony more or less lobed and irregular in form. The divisions proceed in three planes, the cells remain cuboidal, having thin, hyaline Avails and are arranged in rows. In this stage the colony is not unlike certain species of Pleurocapsa. The material is in all stages of development and there are no gonidia. The colonies seem to break up at maturity, freeing the cells which then become spherical and develop a special wall. Although not a typical Anacystis, it seems to correspond more nearly to the stage of development in the life cycle of that genus than to any other.
