A variable species in colour of sporangium and mass of spores
and capillitium. The distinguishing characters are the fusiform
elaters with long, smooth, tapering tips and flat spirals, and
the warted spores. Varying from 2—4 mm. high; solitary, or
in more or less confluent clusters of from 2—7 on a common
stem, which is obviously composed of several confluent stems,
and hence forming a stipitate aethalium. The elaters are
sometimes branched near the tips. I have examined the type
specimen of Trichia lateritia in the Paris Museum, and find
that it agrees exactly with Trichia fragilis iu the structure of
the spores and capillitium.

Sporangia stipitate, ovate or spherico-ovate, solitary or gregarious,
purplish-red, opaque; stem longitudinally wrinkled,
erect or cernuous, rather firm and thickish, expanding at the
base into a small hypothallus, coloured like the sporangium,
which it equals or exceeds in length; mass of elaters and spores
bright ochraceous; elaters rather short, fusiform, attenuated into
long, tapering, smooth, straight or flexuous tips, simple or branched,
about 5 g thick at the centre, spirals sharp-edged, rather prominent
and distant; spores globose, verruculose, yellow, 9—11 g
diameter.

Requires to be carefully distinguished from some forms of
Trichia fragilis, to which species the present is closely allied.
In T. purpurascens the spirals are sharp-edged, in T. fragilis
flattened. The inner surface of the sporangial wall is studded
with amorphous, organic purple particles; the colouring matter
is soluble in potassie or ammonio hydrate.
