Gloeocapsa sphaerica sp. nov.

Plate 3, figure 26

Families spherical to irregular in outline, containing a vari-
able number of cells, up to 128 before the dissolution of the gen-
eral 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 p 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.

Growing on limestone between Arecibo and Utuado, no.
1482 a, type.

The distinguishing feature of this species of Gloeocapsa is
the perfectly spherical form of the young colonies Avith 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.
