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 spherical, 50-80 µ diam., not collected into masses, but free as a rule; cells numerous (100-300) in a colony, mostly angular, moderately crowded, about 4 µ diam., arranged in radial rows, dividing in three planes, the cells on the surface appearing in groups of 2 or 4, dark olive-green or olive-gray, homogeneous; resting spores with thin, smooth Avails; tegument firm, smooth, hyaline, homogeneous throughout the colony, about 6 µ thick outside of the cells.
Distribution and Ecology - Growing in association with other species of Myxophyceae, on rocks in a ravine, Coamo Springs, no. 1901 a, type; on a wall, Governor's Palace, San Juan, no. 58 b ; on old wood in the primeval forest at Hacienda Catalina, no. 755
Discussion:PLATE 5, FIGURE 48
It is difficult to decide whether the above organism should be placed in the genus Anacystis or in the genus Pleurocapsa. It resembles the latter very strongly in the vegetative condition, but since there are no gonidia, a characteristic of that genus, I am placing it with the former in a group with radiating angular cells, awaiting further knowledge of its life history.
