Closely allied to Ghondrioderma testaceum, if indeed it is more
than a geographical variety. Sporangia flattened,, umbilicate
above, frequently dehiscing in a circumscissile manner.
Chondrioderma mntahile, Schroeter.
Sporangia sessile, deformed, hemispherieo-depressecl, or elongated
and curved, reniform, semicircular, &o., 1—3 g long, 1 mm.
broad, hard, fragile, bright, greyish-brmm; columella well developed,
same shape as the sporangium, bright rufous-brown;
threads of capitulum thin, violet, here and there thickened in
a nodulose manner; spores globose, 11—14 g diameter, blackish-
violet, vmcronulate.

On rotten wood. Silesia.
Chondrioderma fallax. Rost.
Sporangia spherical, sessile, yellowish-tohite, seated in numbers,
but not crowded, on a distinct common hypothallus; columella
either minute and flattened, or of medium size'and ovate; threads
fasciculate for some distance then branching copiously, obscure
violet; spores obscure violet: warted, 12—14 g diameter.

B. Golumella absent.
Chondrioderma difforme, Rost. (figs. 85—38).
Sporangia sessile on a broad, base, convex, circular or irregularly
elongated, outer wall snow-white, rather thick, breaking away
in patches, inner wall separated from the outer by a space
containing air, thin, without lime, brownisb-ocbre, sometimes
iridescent; mass of spores blackish; columella absent or represented
by a small accumulation of lime at base of sporangium,
which is covered by the inner wall; capillitium scanty, sometimes
almost obsolete, threads spiringing from base of sporangium.
3—4 g at base, slightly attenuated upwards, forked, pale brown
or colourless; spores globose, smooth, dingy violet, 10—13 g
diameter.
