in size from 10—50 g diameter, have the margin more or less
grooved, and show indications of lines radiating from the centre
to the circumference. These discs occur also rarely in the
capillitium threads.

Craterium cylindricum, Mass. (n. sp.) (fig. 213).
Scattered or gregarious, stipitate, sporangium cylindrical,
elongated, apex rounded, smooth, even, lower portion pale clear
red, white above, upper portion breaking away in a circumscissile
manner; stem thin, elongated, red, like base of sporangium
; capillitium dense, nodes very large, irregularly angular,
filled with yellowish grauules of lime, connected at various
points by long, very thin internodes not containing lime, combined
at the base of the sporangium to form a short columella ;
spores dirty lilac, globose, smooth, 9—10 g diameter.

Stem about two-thirds the length of the sporangium, 2—2'5
mm. high. Allied to C. leucocephalum, but distinguished by
tbe elongated, narrowly cylindrical sporangium, the long, thin
internodes of the capillitium, and the smooth spores.

circumscissile manner; stem usually shorter than sporangium,
orange-yellow, subequal, expanding at tbe base into a small
hypothallus; capillitium dense with numerous large, irregular
knots with yellow or white granules of lime, connected hy elongated,
thin, empty internodes; knots aggregated in tbe centre
towards the base to form a columella; spores globose, brownish-
lilac, minutely verruculose, 8—10 g diameter.

Plasmodium clear lemon-yellow. Scattered, 1’5 mm. high,

and the long slender internodes in the capillitium, in which
respect tbe present species approaches the genus Physarum.
