Craterium Curtisii, Mass.
Gregarious, sessile, obovate, fixed by a point to a very tbin
liypotballus, imiber-brown, wall tbin, smooth or sometimes rugulose,
soon disappearing at the apex; capillitium dense, nodes
large, irregular, separated only ly short constrictions, everywhere
containing pale brown granules of lime, the nodes become
confluent towards tbe base and form an irregular columella ;
spores brown with indistinct lilac tinge, globose, minutely warted,
7—8 g diameter.

On leaves, grass, &c. United States.
Sporangial wall very thin, shining, containing very little or
no lime. About 1 mm.
Craterium Fuckelii, Mass. (n. sp.).
Sporangia perfectly globose, contracted below into a short,
stout stem, every part broimish-ochre, upper portion breaking
away in an irregularly circumscissile manner; nodes of capil-
btium large, angular, combining towards the base to form an
irregular columella; spores dirty lilac, globose, rather coarsely
warted, 12—14 g diameter.

On wood. Germany.
Distinct from C. aureum in the globose, differently-coloured
sporangia, tbe absence of tbe long, thin internodes of the
capillitium, and the larger, coarsely-warted spores.
Craterium minimum, B. and C.
Sporangia broadly elliptical, apex convex, breaking away in
an irregularly circumscissile manner, pale yellow, becoming
brownisb towards the base, as is also the very short, equal stem ;
nodes rather scanty, large, irregularly angular, connected at various
points hy rather long, thin internodes; spores globose, dirty lilac,
7—8 g diameter, smooth.

On herbaceous stems, &o. Lower Carolina.
Usually growing in lines on slender, dead herbaceous stems,
'5 up to nearly 1 mm. h ig h ; tbe long, thin internodes of the
capillitium are unusual in tbe genus.
Craterium minutum, Kickx.
Sporangium stipitate, campanulate, rounded and umbilicate
below, 1—1'5 mm. long, of a yellowish clay-colour, tinged
brownisb or reddish towards the base, sprinkled with very
minute, wart-like, paler spots. Operculum the same colour as
the upper part of tbe sporangium. Filaments whitish. Spores
globose, black. Stem 2, rarely 3 mm. high, attenuated towards
the apex, wrinkled, often compressed, russet-brown or reddish,
springing from a blackish-brown indistinct hypothallus.
Craterium minutum, Kickx, Flor. Flanders, ii., p. 23.
On rotten wood.
The present species is considered as a species of Tilmadoche
by Rostafinski, but as his description differs very materially
from that of Kickx, the latter is given above. There is
no reason, judging from tbe description alone, to show why
Kickx was not quite correct in considering his specimen as a
Cratermm.
P hysarum, Pers.
Sporangia solitary, plasmodiocarp, or combined to form an
aethalium, wall single or of two distinct layers; threads of
capillitium springing from all parts of the sporangial wall,
combined to form an irregular network, with the numerous
nodes or angles very much and irregularly swollen and filled
