Aphanocapsa Richteriana major var. nov.

Plate 1, figure 9

Cells 3.6-4.5 m diam., aggregated into very irregular, but defi-
nite colonies 2-3 mm. diam., elongating previous to division,
pale aeruginous to greenish gray; tegument firm, honey-colored,
more nearly hyaline on the interior, the tegument persisting on
the surface of the colony around single cells or groups of 2-4,
but not showing on the interior of the colony.

Growing on soil in the primeval forest by Hacienda Catalina,
Palmer, no. 754 a, type.

On the surface of the colonies of this species of Aphanocapsa
the teguments persist and are plainly visible through two to
three generations of cells before merging into the community
tegument. That part of the colony resembles the genus Gloeo-
thece, but on the interior of the colony there is no trace of the
individual tegument.

The cells are rarely,’ if ever, two times as long as broad, but
are longer on the surface of the colony than in its interior, where
they are spherical.
