I.—NOTES ON UGANDA FUNGI.
I.—TuHEe FunGus-FLORA OF THE FORESTS.
T. D. Marruanp and E. M. WaKkeFIELD.
Botanist in the Agricultural Department, Uganda, and of Mr.
R. Dummer. The species received now number some hundreds,
and although far from exhausting the mycology ot the region,
they appear to be fairly representative of the types of fungus
flora to be found, at any rate in the Uganda Province. It has
therefore seemed advisable to place on record some of the know-
ledge which has been acquired, the more so because, as far as we
are aware, the only list of Uganda fungi previously published is
that of the collection made by Scott Elliot during the Ruwenzori
expedition. sacins
‘The present account deals only with those sane chiefly the
macro-forms, which occur as saprophytes in the forests. With
the exception of the few species collected by Mr. Small on
Mount Elgon, the fungi enumerated all come from forests lying
in the eastern part of the Uganda Province. There are other
large forests in the western district which have not been touched,
but their fungi are probably not strikingly different from those
of the forests visited.
Ecorogicat Notes.
(T. D. Maitland.)
The first collections of fungi were made in several small forests
lying within the Victoria Nyanza region, north-west of Lake
Victoria Nyanza. The names of these forests are Wakigu,
Namamywe, Nabaziza, Ntongo, Bumpenge, and Namutambula.

to Entebbe on the other. It will be seen that their dispositions
are not varied enough to provide extensive modifications in their
vegetation, and that a description of one forest will serve for

always on dead palm stumps, but are by no means confined to the
forests, for an abundance of these growths is found on palm
stumps in farm clearings and plantations. The most conspicu-
ous of the larger Aig of these regions belong to the Poly-
poraceae. They are found principally on loose fallen branches,
in many instances ‘ping on the top of the undergrowth. Poly-
orus gil: us, however, is usually, if not always, found on much
decayed fallen tree trunks in shady positions. Polystictus occi-
dentalis, a common fungus, is another exception, as when found
in the forest it is usually in open airy places. Most of the
specimens of this species were gathered in the open country and
invariably on smooth-barked trees, such as Albizzias. Poly-
stictus sanguineus is, one may safely say, confined to outage

The second series of forests visited run along the sansa
boundary of the Mawokota District. They commence at.about
mile 16 on the Kampala-Mubendi Road, and continue to about
mile 26, but here deviate somewhat from the main road. The
sections visited are known as Balisangakibugo, Tiriulire, Mwen-
gizanyagi, Nakatumba, and Nakinyika, and are drained by the

n general character. they do not vary to any considerable
extent from those strictly in the Victoria Nyanza region. The
same undergrowth is met with—Dracaena, Amomum, Cyperus,
lanes, and in parts a low shrub. This undergrowth is,
generally speaking, not difficult to penetrate, and only when
nearing the outskirts of the forest is a more tangled and denser
vegetation encountered. This consists first of a thick shrubby
erowth, then of a mixture of Elephant Grass (Pennisetum pur-
pureum), prickly se srr —— spp., and Cucurbitaceae.

The forest trees are, ta nythi si more striking here than in

with Usnea-like lichens hanging from their branches are very

rounding country and in these forests.
The fungus-flora is more or less identical with that of the
forests i in Kiagwe and Busiro, round the lake, since the forests
are in most respects alike. Of the Polyporaceae the most
abundant representative seen was Polystictus aratus. This
species was plentiful on stout fallen branches and on dead
branches still adhering to the tree. Sterewm lobatum was widely
ispersed, and the forms here were larger than any previously
gathered. Species of Xylaria were also very numerous, including
some very stout forms of X. grammica. The following fungi
