Trichia antiades, D.C., FI. Fr., 2, p. 252 ; Chev., Par., p. 325.
On rotten wood. France.
Stem thick, deformed, several confluent, branched, irregularly
lacunose; hypothallus membranaceous, w h itish sp o ran g ia dehiscing
by irregular rupture towards the apex from wliicb tbe
capillitium protrudes. (Fr.)
Judging from Bulliard’s figure, and also from some points in
the description, tbe present species is much more likely to be
a Orihraria than a Physarum.
Physarum retieulatum, Berl.
Sessile, oblong or subdeformed, aggregated, externally black
or greyish; sporangia smoothisb but elegantly reticulated;
spores black; threads of capillitium whitish, rare.

On bark. Bethlehem; United States.
Allied to Physarum cinereum, but larger. (Sz.)
Scbweinitz’s specific name was antedated by Persoon.
Physarum fimetarium, Schum.
Sporangia obovate, pale purple-umber; stem short, sub-
flexuose; capillitium and spores brown.

Myo., iii., p. 138; Sacc., Syll, vii., 1, n. 1214.
On oow-dung. Scandinavia.
Scattered; at first semi-liquid and white, then yellowish,
piriform, substipitate, at length purple-umber; sporangia becoming
torn at tbe apex; stem subflexuous, slightly thickened
upwards. (Schum.)
Physarum hypnophilum, Fr.
Subsessile; sporangia rounded, smooth, bay-coloured;
very delicate threads and spores black.
Physarum hypnophilum. Fries, Stirpes Femsj., p. 83; Sacc.,
Syll, vii., 1, n. 1217.
On Hypnum cupressiforme, growing on damp rocks. Sweden.
Scattered or gregarious, hypothallus not persistent; stem
either absent or very short, rather thick, subdeoumbent, coloured
like tbe sporangium, which is very delicate, subglobose or
attenuated at the base, the size of a turnip-seed, bay, rather
shining, dehiscing by the irregularly torn apex; rugulose when
old, but not hyaline, threads very slender, black, adnate to tbe
wall of the sporangium. (Fries.)
There is a specimen of Lamproderma physaroides, sessile or
nearly so, marked “Physarum hypnophilumff by Fries, and
judging from the above description, Fries had probably bad a
Lamproderma in view; tbe bay colour is rather against this idea,
unless the coppery tint often present on the waU was intended.
Physarum atrum, Fries.
Closely aggregated, confluent, black; sporangia very thin,
rounded; capillitium threads none; spores black.
Physarum atrum, Fr., Syst. Myo., iii., p. 147 (not of Schweinitz);
Sacc., Syll, vii., 1, n. 1221.
Lycogala atra, Pers.
On dead trunks.
Sporangia adnate by a broad, flat base, rounded, connate
from the centre downwards, often densely crowded and forming
a continuous patch 2 mm. broad; dehiscmg irregularly, spores
very abundant. (Fries.)
Kostafinski says (Mon., p. 302), that tbe present species is
not a Myxogaster but an Apiosporium, probably A . imersum,
but he had not examined au authentic specimen from Fries,
and as Fries’ description of the present species does not agree
at all witb the genus Apiosporium, it appears at best doubtful
as to whether this synonymy is correct.
Physarum puleherripes, Peck.
Peridium globose, variable in colour, oohraceous, grey, brown,
