A 
related to L. atropurpureum, but that is described as „at 
first rougb with minute spines“, thus indicating that it be- 
comes smooth afterwards. It is also said to be „dingy- 
rufous“, but our plant is constantly yellow. 
Milleria gen. nov, Peridium membranaceous, enclo- 
sing numerous minute sporangium-like bodies bearing upon 
the surface a stratum of spores, 
This is a genus of Gasteromycetes, near Polysaccum. 
It is respectfully dedicated to its discoverer. Mr, E. $. 
Miller. 
Milleria herbatica Pk. Peridia oval or ovate- 
conical, subobtuse, firm, externally minutely warty or mealy- 
furfuraceous, whitish, inclosing a mass of minute subglobose 
or slightly angular sporangioles adhering together, black 
externally, pallid within; spores superficial on the sporan- 
gioles, globose, colored, .0005°—.00065‘ in diameter. 
Panicles of Rhynchospora macrostachya. 
This rare, but interesting fungus resembles in size and 
color the Lycoperdon calyptriforme, but its interior structure 
is wholly different. The sporangioles appear to be composed 
of densely compacted or reticulated threads and cellular 
matter. l have not been able to detect any investing mem- 
brane, the spores appearing to rest directly upon the surface 
to which they give the black color. T'he peridium does not 
appear to have been ruptured naturally in any of the 
specimens. The cavity is only partly filled by the mass of 
sporangioles. 
Physarum ornatum Pk. Sporangia depressed or 
hemispherical, plane or slightly concave beneath, greenish- 
einereous, dotted with small yellow granules, the empty walls 
whitish; stem short, black or blackish-brown, ‚generally lon- 
gitudinally wrinkled when dry; columella none; capillitium 
with numerous yellow knot-like tbickenings; spores globose, 
smooth, violet-brown in the mass, .0004’—.0005‘ in diameter. 
Decaying wood. Aug. i 
Physarum atrorubrum Pk, Scattered or gregarious, 
stipitate; sporangia globose, even or somewhat wrinkled, 
dark-red; stem eylindrical, even, blackish or subconcolorous; 
eapillitium when cleared of the spores whitish, sometimes 
with a slight pinkish tinge; columella none; spores globose, 
smooth, dark-brown in the mass, dark-red when separated, 
.0003°— ,00035° in dansie: 
Decaying wood. ne HE ERr, 
The au are An one line high. The capillitium 
is very delicate, and when cleared of the spores, the knot- 
like Wickedinpk are seen to be very small and of a dark-
