UMIVERSITATIS LATVIENSIS - DSpace

compared with the length of the capsule, the peristome is insert-
ed below the mouth and the teeth are higher
ly acuminated than in U. lutea. In this genus
and more narrow-
U. breviseta and
U. lutea afford another example of how very much alike the
leaf form can be in species which are quite different in their
sporophyte characters.
Besides the specimens
mentioned above there is another
specimen in Herb. Broth, gathered by Bell in the same locality
as the first some months earlier (Mungatui, IX 1887,
on dead
beech). It has shorter capsules with a shorter seta and shorter
peristome and shows smaller but stronger papillose spores than
the specimen gathered in Jan. 1888. I do not think it is more
than a somewhat stunted form of U. breviseta.

Ulota laticiliata n. sp. )
Autoicous. Plants in yellowish tufts, brown below. Leaves
curled when dry, erecto-patent
when moist, lineal-lanceolate, acu-
minated, gradually dilated into an oblong base. Margins almost
plane.
Nerve brownish or fuscous, ending shortly
below the
apex. Cells in the middle of the base very narrow and incras-
sate, often fuscous; cells in 6—9 rows at the margins
of the
base forming a conspicuous band of hyaline cells; in the upper
part of the lamina cells small, irregularly-rounded,
B—lo v.. Peri-
chaetial bracts of varying form, longer than the leaves. Vagi-
nula with a few paraphyses. Seta of varying length, s—B mm,
reddish-yellow, distinctly twisted. Capsule yellow, reddish at
the mouth, rather short, 1 — 1,6 mm when dry, oblong
or sub-
cylindric, distinctly ribbed, not or but slightly contracted below
the mouth,
urceolate when old. Stomata in the neck. Lid of one
colour. Calyptra hairy. Peristome double; teeth 8, spreading at
the fall of the lid, finely papillose, slightly striated in the upper
part, afterwards splitting; processes 8 broad often with a zig-zag
median line, slightly striated. Spores papillose, 24-34 p.. Fig. 5;
1 d-e.
