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 moderately firm and rigid, spherical, containing 2-4 cells, agglutinated into masses of indefinite extent; cells slightly elongated, 2-2.5 µ diam., 1.25-2 times as long as broad without the tegument; tegument opalescent, homogeneous, firm, about 3 times as thick as the lumen of the cell.

Distribution and Ecology - Growing on limestone, near Hato Arriba, Arecibo, no 1434, type.



This species is on the border line between Gloeothece and Gloeocapsa. The cells in a state of division are mostly spherical, but when in the resting stage they average about one-half longer than broad.

The colonies remain spherical even in large masses, the mutual pressure not being sufficient to distort them, the teguments being firm. They are sufficiently sticky on the surface, however, to cause them to adhere very firmly to each other. The species has a near relative in Aphaiwthece opalescens of this paper.
