all Trichias, sporangia will be found in winch the elaters are
branched or distorted, or have a tendency to buibous expansions
near the ends or in their course, but these are abnormal and
exceptional. The specimens distributed under this number
(2495) were collected in August 1889, with a few exceptions.
The unusually wet season had the effect of rendering many of
them much darker in colour than is indicated iu the foregoing-
specific diagnosis, which was drawn from types developed and
collected under the most favourable conditions. (Rex.)

Trichia reniformis. Peck.
Sporangia gregarious or clustered, sessile, subglobose or reniform,
small, brown; flooci few, short, sparingly branched; spores
globose, minutely eehinulate, yellow-ochre, sometimes tinged
with green, -0005 in. in diameter ( = 12—13 f .

I am not acquainted with the present species, and the information
given by Peck is too scanty to insure future identification.
§ § Spirals spinulose.
Trichia erecta, Rex.
Sporangia stipitate, usually simple, occasionally double or
triple and very rarely fasciculate, with a cluster of 6— 8 on a
single stipe. Single sporangia globose or globose-turhinate
\—f of a mm. in the transverse diameter.
Colour of sporangia a dark nut-brown, which is uniform
below, but checkered or broken above into irregular patches
with broad septa of a bright yellow colour.
Stipes about 1 mm. in height, rough or granular on the
surface, quite thick and equal throughout their length, and
dark brown in colour. Spores and capillitium concolourous,
being a bright yellow colour in mass.
Elaters cylindrical, 3-75—4 g in diameter, terminating in
short, sharp, smooth ends 4—6 g long. Elater spirals 4 in
number, spinulose with numerous irregular spines, coarse, winding
irregularly. Adjoining spirals often united with each other
by° intei-spiral branches which run either longitudinally or
obliquely in the direction of the spirals.
Spores 12—13 g in diameter, delicately warted when examined
under a high power lens.

This Trichia is conspicuous for the checkering or areolation
of the upper surface in the perfectly mature sporangia, showing
a sharp contrast between the adjoining nut brown and bright
yellow colours. In this respect it resembles Tr. fragilis, which
sometimes exhibits in its var. lateritia and also in one of its
simple forms, a dull mottling of the colour of the upper surface
of the sporangia.

Trichia Decaisneana, De Bary.
Sporangia pyriform, brownish flesh-colour, shining, stipitate;
stem red, then blaokish-hrown, very much plicate, equal; mass
of capillitium and spores yellowish flesh-colour; inclosed in an
inner membrane connate with the miter wall of the sporangium;
elaters cylindrical, inflated near the tips and ending in smooth,
tapering, curved spines 3—6 times cm long as elater, spirals 5—6,
flexumis, spinulose, in some oases parts of the elaters have the
spirals in the form of distant ridges or wrinkles; spores deliccdely
warted, 10—11 g diameter.

According to Schroeter the spores measure from 13—14 g,
tiie elaters have 4 spirals, and are 4—5 mm. thick. As these
measurements differ from those given hy tlie author of the
