Sporangia slightly scidellate, snow-white, stipitate; stem rigid,
ba:y at the base, becoming paler tipwards; threads of capillitium

There is no specimen in the Berkeleyan Herbarium answering
to tbe above description, and in tbe “ Introduction to
Cryptogamic Botany,” p. 335, tbe spores are described and
figured with a reticulate epispore.

Gregarious, sessile on a broad base, circular or irregularly
elongated, depressed, outer cretaceous wall polished, pure white
or ivory tinted, inner wall dirty ochraceous, sometimes separated
from the outer wall by a space containing a ir ; columella obsolete;
threads of capillitium equal, about 3 g thick, colourless, sometimes

On rotten wood, leaves, &c. Britain (King’s Cliffe, Black-
heath, Carlisle); France ; Switzerland.
Sporangia 1—3 mm. when circular, from 3—5 mm. when
elongated; in the elongated form the sporangium is frequently
folded on itself, and sometimes it takes two or three spiral
turns, leaving a minute cavity in tbe centre. Distinguished
from Ghondrioderma difforme by the warted spores and large
size of the sporangia, and from G. niveum by tbe absence of
the columella. Sometimes the whole of the outer calcareous
coat breaks away in a circumscissile manner close to the adnate
base.

Effused or circumambient, crowded, sessile, subglobose, smooth,
white, outer peridium crustaceous, like the shell of some small
egg, the inner delicate, appearing cinerous to the naked eye,
iridescent under tbe microscope; columella none; spores
globose, black, '0005 in. in diameter ( = about 13 g).

Owing to absence of information respecting the capillitium
and presence or absence of markings on the epispore, tbe
position of the species is uncertain.

Plasmodium scarcely as thiclc as a needle, creeping or piulvinate,
wall highly charged with lime, white externally, inside reddish-
brown; inner wall contiguous to outer, delicate, violet; capillitium
fairly abundant, threads simple, or mice or twice dielioto
