On fallen branches. [Low. Carolina.]
The structure of this plant is at present very imperfectly ascertained. The
flocci are of a vinous-brown, and here and there invested witb mucilage.
Tbe larger sporangiform bodies which adhere to them seem very much to
resemble an Epicoccum, with its globose, or somewhat obovate scabrous
spores.—J /./.B . (Fig.%i5.)

Tulasne does not consider this a true genus,
but made up of forms, which are conditions of
different species of Sphceria. New facts are continually
strengthening this opinion, but at present
only a few species have been satisfactorily
traced ; hence we have retained all, provisionally.

On dead holly twigs, &o. Common.
Tufts effused when growing on the wood, linear, and often forming somewhat
reticulate, erumpent patches when produced on the bark, rather spongy,
coarsely velvety ; threads simple, flexuous, articulated ; articulations irregular,
several times as long as broad ; spores terminal, extremely long, linear,
mnlti-articulated, sometimes bent or flexuous ; general epispore double, the
outer coat thin, the inner extremely thick ; endochromes united, about as
long as broad, sometimes moniliform, or very irregular, here and there surrounded
by a broad cavity, which appears granular under tbe microscope.—
