Discussion:

PLATE 3, FIGURE 27

The variety is to be distinguished from the species in having larger and ellipsoidal colonies, in having elongated cells and in having yellowish-brown tegument on the surface of the stratum when aged. The cells are distinctly elongated, a character not, strictly speaking, that of a typical Gloeocapsa, but the cells divide in three planes, thus excluding it from the genus Gloeothece.
