(The above description drawn up from a specimen named by

On mosses, &c. Britain (Wales); Sweden; Germany.
Usually growing on living mosses, scattered, I'o—2 mm.
high; stem stout. Very closely allied to Physarum Ditmari,
Eost., of which the present may possibly prove to be a stipitate
form; however, in tbe absence of such evidence, it is well for
the present to retain it as a species.

Physarum Sehroeteri, Rost.
Sporangia stipitate, hemispherical, depressed; stem conical,
thick, golden, shining, continued as an obtusely conical columella;
threads of capillitium slender, combined to form a dense network,
furnished with nodes containing lime; spores spinulose,
blackish-brown, 10—12 g diameter.

Physarum brunneolum, Phillips (figs. 221, 222).
Scattered or gregarious, but not crowded, sessile; sporangia
globose or subdepressed, wall single, thick, smooth and polished,
briyld yellmo-broum, dehiscing in a stellate manner, the segments
becoming reflexed, snow-white inside; columella absent; capillitium
very dense, snow-wbite, nodes very large and numerous,
irregularly angular, filled with lime, connected at several points
by very thin, short internodes ; spores globose, dirty lilac, very
minutely verruculose, 6—7 g diameter.

On oak bark. San Francisco.'
A very beautiful and remarkable species, reaching up to
1 mm. in diameter. Intermediate between the genera Chondrioderma
and Physarum, agreeing with the former in the
polished, porcelain-like sporangial wall dehiscing in a stellate
manner, and with tbe latter in the structure of the capillitium,
whereas tbe very large and numerous nodes of the capillitium
separated from each other by constrictions rather than by true
internodes, suggests affinity with tbe genus Badhamia.

Physarum Bavenelii, Mass. (figs. 234, 235).
Scattered, stipitate; sporangia perfectly spherical, not umbilicate,
dirty brown, sometimes rugulose; stem elongated, rathur
slender, equal or slightly fusiform, coloured like tbe sporangium,
filled with granules of lime; columella absent; capillitium
copious, forming an irregular n e t; nodes small, filled with yellow
granules of lime, internodes thick, elongated, colourless, empty;
spores dingy lilac, globose, very minutely verrueidose, 6—7 g
diameter.

On wood. Sulphur Springs, N. Carolina.
From 2 5—3 mm. high. Remarkable for tbe dirty brown
colour of sporangium and stem. In form and size almost
identical witb Physarum Kalchbi'cnneri. Tbe knots of the
capillitium are small and usually elliptical, resembling those
characteristic of Tilmadoche, but the capillitium is altogether
too robust to admit of the present species being placed iu the
