Chroococcus subsphericus sp. nov.

Plate 2, figure 13

Families composed of 2-4 cells, free among other algae,
spherical or subspherical, not forming a stratum alone; families
of 4, 16-19 m diam. with the tegument; single cells 8-10 p diam.
with tegument, 6-6.5 p without tegument, purplish drab or gray;
tegument hyaline, homogeneous.

Growing among other Myxophyceae on a wall by Hot
Springs, Coamo Springs, no. 402 a, type, and no. 403 a.

The above-described species seems to be nearest related to
C. caldariorum Hansg. There is much less variation in the size
of the cells, and the color is not so intense, as has been attributed
to that species.
