Authority: Gardner, Nathaniel L. 1927. New Myxophyceae from Porto Rico. Mem. New York Bot. Gard. 7: 1-144. pl. 1-23.
Description:Species Description - Families spherical to irregular in outline, containing a variable number of cells, up to 128 before the dissolution of the general tegument, soft, subgelatinous, adhering to each other at times, forming masses microscopic in size; cells spherical to slightly elongated before division, yellowish green, 2-2.3 µ diam., usually separated from each other in the colony by 2-3 times their diam.; teguments homogeneous, opalescent, ample, smooth on the surface; teguments of individual cells arising soon after cell division, not persisting long, but merging into the colonial tegument.
Distribution and Ecology - Growing on limestone between Arecibo and Utuado, no. 1482 a, type.
PLATE 3, FIGURE 26
The distinguishing feature of this species of Gloeocapsa is the perfectly spherical form of the young colonies with an ample, homogeneous, opalescent tegument, and not a more or less angular colony, as is the case in most species of the genus in the juvenile stage. It seems closely related to G. squamulosa Breb., which has a thick, hyaline tegument. It differs from that species in having the cells associated into much larger families, with a larger number of cells in the family.
