0®®- From the other fetid Fossombroniæ, distinguished by its
still stronger disagreeable smell.
The spores are similar to those of F. angulosa, only with more
numerous and much smaller pits, the ridges are more depressed
and the marginal projections number from 20 to 30.

Fossomhronia cæspitiformis, De N. in G. E . Hep. eur. dec. 13 e t 14, n. 123.
Heteroicous, fetid, cæspitose, small, of a green colour. Stems
procumbent or sub-erect, simple or slightly branched, on a cross-
section suhterete; radiculose, rootlets violet-purple. Leaves
crowded, obcuneate, sub-quadrate or oblong-quadrate, lobate, lobes
obtuse; texture delicate, cells medium size, sub-quadrate, walls
thin, no trigones or thickened angles. Bracts sub-quadrate or
roundish-obovate, margin denticulate. Perianth obpyramidal,
plicate, mouth wide, irregularly lobate-dentate. Calyptra delicate.
Capsule globose, dark brown. Spores dark brown, tetrahedral-
globose, densely echinate, spines obtuse, numerous, about 25
projecting around the margin ; elaters long, pale brown, bi-rarely
tri-spiral.
Androeoia usually situated below the perianth, exposed or in the
axil of the bracts, or more rarely on separate plants.

Monoicous ?, cæspitose, small, bright yellowish-green in colour.
Stems simple, prostrate, creeping, fragile, radiculose ; rootlets
numerous, of medium length, bright reddish-purple in colour,
giving the stem the appearance of being purple throughout.
Leaves overlapping each other by about one-third of their breadth,
more crenulate than lobed, much crisped, slightly angled, the
