Sporangia subglobose or slightly attenuated at the base, substipitate,
wall thin, pale yellow, sometimes witb a greenish tinge,
rough with numerous crystals of lime, becoming irregularly
ruptured at tbe apex; the very short stem is rufous, longitudinally
wrinkled, and expands into a minute hypothallus;
columella absent; capillitium rather dense, nodes irregularly
stellate-angular, large, containing colourless granules of lime,
internodes elongated, very thin, colourless, without lime; spores
globose, pale lilac, minutely warted, 7—8 g diameter.

From I—f mm. high. A very fine specimen named as above
was sent to me by Mr. H. Wingate, of Philadelphia. It appears
to differ from Physarum chrysotrichum only in the white nodes
of the capillitium and the very short stem.
Physarum ruflhasis, B. and Br.
Scattered or gregarious, stipitate; sporangia globose, dull
yellow or tawny, even, sprinkled with minute particles of lime,
dehiscing irregularly; stem elongated, slender, tapering upwards,
longitudinally furrowed, expanding at the base into a small,
circular hypothallus, bright brown, filled witb minute granules of
lime; columella absent; oapill itium dense, forming an irregular
network, nodes incrassaied, irregularly angular, large, numerous,
filled with bright yellow granules of lime, connected at various
points by rather thin, long internodes ; spores pale lilac, globose,
very indistinctly verruculose, 10 g diameter.

A very fine species, about 2 o mm. high, resembling a Tilmadoche
in the small sporangium and long, slender stem, but tbe
nodes of the capillitium are large and stellately angular.
Physarum flavum, Fries, (fig. 215).
Scattered or gregarious, but not crowded; sporangia globose
or slightly depressed; wall rugulose, rigid, bright lemon-yellow,
sometimes with a tinge of green, breaking away in irregular
patches; stem stout, about equal to sporangium or shorter, bright
yelloiv, Y e i j much longitudinally wrinkled, containing amorphous
masses of lime, expanding at the base into a small hypothallus;
columella absent; capillitium rather dense, nodes irregularly
