or black; stem slender, equal, or slightly tapering upward,
vermilion; spores globose, brown, '00033 in. in diameter ( =
about 9 g).
Physarum pndeherripes, Peck, 26tb Report, New York State
Mus., p. 75; Saco., Syll., vii., 1, n. 1207 (as P. pulchripes).
Rotten wood. Richmondville and Worcester.
Tbe bright colour of the stem is quite conspicuous, notwithstanding
the small size of tbe plant.
Physarum polyaedron, Sz.
Gregarious or slightly scattered; sporangia rather large,
smoky-black, dull, subhemispherioal, exactly pentagonal, sides
plane, rugulose, dehiscing in an irregularly stellate manner,
lower portion persistent; spores smoky-black, mixed with
threads of a similar colour.

Schweinitz says the present species resembles some minute
sea-anemone.
Badhamia, Berk, (emended).
Sporangia stipitate or sessile, wall single, dehiscing by the
irregular rupture of tbe upper portion ; threads of the capillitium
springing from all parts of the sporangial wall, combined to
form an irregular network, usually thick, and containing granules
of lime throughout their length; columella absent; spores
originating in clusters or free from tbe first, globose or elliptical.

The genus, as founded by Berkeley, was characterized by the
clustered spores, a feature now well known to be far from
constant, even in the same species; Berkeley further considered
that the clusters of spores originated in hyaline cysts or mother-
colls; this has not been corroborated. Tbe genera included in
the Physarae are very closely allied, in fact so much so, that
only the most typical species can be recognized from the features
usually considered characteristic of each, numerous transitional
species connecting the genera at various points. The most
pronounced character of Badhamia, as defined above, is tbe
thick capillitium threads which contain lime in the form of
small granules throughout their entire length, and not concentrated
in large nodes separated by thinner portions without
lime, as in the genus Physarum. Very closely allied to Graterium.
For distinguishing features see note following last-named genus.

§ Spores equally warted all over.
Badhamia maorocarpa, Rost. (figs. 79—81 and 294—297).
Sporangia gregarious or scattered, stipitate. or sessile, springing
from a slender hypothallus. subglobose, grey, base dirty
brownish-ydlow, this colour usually continuing upwards in a vein-
lihe manner, upper part of sporangium with vein-like patches
of white lime, wall tbin, stem wben present variable in length,
rather stout, hrownish-yelloio, or pale, rugulose; capillitium
dense, knots numerous witb scattered granules of lime; spores
free, globose, equally warted all over, the warts sometimes show
a tendency to become elongated, brownish-purple, 10—15 g
diameter.
