Nostoc Erittonii sp. nov.

Thallus spherical, up to 2 mm. diam., firm, smooth; trichomes
very tortuous, moderately crowded, 3.6-4.8 ¡j diam.; cells dolio-
form to subspherical, bright violet or drab, fading to greenish;;
heterocysts spherical, single in the juvenile stage of the tri-
chome, later, on the formation of hormogonia, two or more are
formed, these usually being somewhat smaller; tegument opales-
cent when young, changing to purplish drab, and finally to yel-
lowish brown; resting spores unknown.

At “Campo” south of Maricao, collected by Dr. N. L. Brit-
ton, no. 1290 a, type; collected by Dr. Wille in the same locality,.
no. 1229 c.

No resting spores have been observed in the material of this
species of Nostoc. Some of the colonies, however, are mature
and have formed hormogonia with definite individual teguments
showing the beginning of new colonies. After having been dried,
the color seems to diffuse out of the trichomes into the tegument
when wet.
