Owing to an oversight, Enerthenema Berkeley ana was introduced
by Cooke in Myx. Brit., p. 51, as a native of Britain.
This species, so far as I am aware, has only been met with in
S. Carolina, and is known by the clustered spores.

Enerthenema phoenicolepta, Bowm., msc.
Enerthenema Berkeleyana, Rost.
Sporangia stipitate, globose, blackish, wall evanescent; stem
black, very thick at the base, conical, becoming contracted into
a thin, cylindrical, black columella that reaches to the apex of
the sporangium, and there becoming expanded into a disc;
capillitium threads dark, springing from the margin of the disc,
pendulous, sparingly forked, rarely joined laterally; spores
blackish-purple iu the mass, at first in clnsters of 4—14, sub-
triangular at Ant, free portion warted, 10—13 g diameter.

Cn boards. South Carolina.
Closely resembling S. elegans, but distinct in the clustered
spores that are warted on the free surface only. The stem is
not always thickened below.
Enerthenema muscorum, Lev.
Gregarious, black; stem setaceous, smooth, expanding at the
base into a shield-like hypothallus; sporangium smooth; tubes
of the capillitium springing from the lenticular apex of tlie
columella ; simple for some distance, then branched in a
diehotomous or vague manner; spores globose, brown.

The information respecting the present species is insufficient
to indicate its specific features with exactness.
Ancybophorus, Raunk.
Sporangium stipitate. Stem prolonged within the sporangium
as a columella, reaching the apex of the sporangium and there
expanding into a discoid membrane. Capillitium originating
from this stout discoid membrane, and from the upper part of
the columella proper. Threads of the capillitium only towards
the extremities inconsiderably forked, the extreme branches
arcuate and furnished with numerous subulate spines.

(Journ. Bot. Soc. Bot. de Copenhague), 1888, p. 92, and 1889,
p. 110 (in English).
Clossly allied to Enerthenema, known by the branches of the
capillitium springing from the upper portion of the stem as
well as from its discoid apex.
Distrib. Denmark. Species 1.
Ancyrophorus crassipes, Raunk.
Sporangia globose, stipitate. Stem shorter than the sporangium,
from an exceedingly thick base lengthened directly
into the subulate columella. Threads of capillitium combined
by very few transverse branches. The extreme branches arcuate,
and provided with numerous subulate spines. Stem, columella,
and capillitium dull violet-black. Spores smooth or delicately
warted; bright violet, 10— 12 g diameter.
