Nabuvumba Forest, in Busiro district, in many respects re- 
sembles Nakinyika Forest, in Mawokota, both being for the most 
part humid and swam y. <An outstanding feature of Nakinyika 
Forest is the numerous Landolphias and fine large trees ot 
Canarium pega uu. 
In Bulimezi, Kangavwe Forest is rather remarkable for the 
huge sae disper sed throughout, many of them moss-covered. 
Not m y fungi of a striking character were met with there, 
ee rimosus being the most outstanding. In addition to 
those sent, Stereum Schomburgkii, Polystictus hehe: on the 
edge of the forest, Laschia Volkensiwi, and several Agarics were 
observed. This forest covers the top of Kan ngarwe Hill (1274 m.) 
in lat. 0°35° and long. 32:20°. The dry aspect in all probability 
accounts for the paucity of fungi as compared with the forests 
in the valleys. 
The Mabira Forests, visited in September, 1915, lie within the 
Nile and Sezibwa River watersheds on the left bank of the 
Nile, and about 15 miles from the Ripon Falls, where the Nile 
leaves the Great Lake. They extend north to the great Sezibwa 
Swamp and cover an area of about 137 square miles. 
One outstanding feature of these ai ae as compared with most 
ad is the wide distribution of the rubber tree Funtumia 
tive ease, for undergrowth—except where some ss trees 
have been felled and have thus given it the advantage—is not 
sufficiently thick to necessitate cutting a way through. Dra- 
caenas form a large part of the undergrowth, and also young 
seedling forest trees and lianes. Numerous paths made by 
animals ramify through the forest. 
_ The climatic conditions of this large forest area differ from 
those of the surrounding country. The rainfall is greater and 
the humidity higher. Hence, with the fallen trees and branches 
and other decaying vegetation, oe are very favourable 
for the development of a ric 
About 28 miles of the forest were S Eaursed and many speci- 
mens collected which were not represented in the gatherings 
from other forests. Speaking generally, however, the fungus- 
flora is very similar to that found throughout the Victoria 
Nyanza Region. Fomes rimosus was collected here, for the first 
time in the Victoria Nyanza Region, and was well represented. 
It was found in low-lying, humid places, contrasting with its 
habitat in the high and dry Kangavwe Forest in Bulimezi. . Len- 
zites repanda is perhaps the most abundant species, and is not 
confined to the forests, for it occurs abundantly on dead stumps 
in clearings and plantations on the outskirts. Zrametes cor- 
rugata is also very common, but confined to the more open parts 
rather than to the interior. ly one specimen of Fomes horno- 
dermus was found, on a live tree six feet up the trunk, but
