With regard to the arrangement adopted in this paper, t 
genera are listed alphabetically and the species alphabetically 
under their respective genera. The genus Polystictus is merged 
in the genus Polyporus. The host-plants are listed alphabetically 
under the various species. Where no name is given the host- 
plant was undetermined. 
The list contains a few species believed to be new and indicated 
accordingly. These will be described in a monograph of the 
South African species to be published later. 
oS most of the countries where forestry plays an important 
art ever-increasing attention is being devoted to the causes of 
the decay of trees and timber for which this group of fungi is 
largely responsible. A knowledge of their distribution over the 
globe is for this reason very desirable, and it is hoped that the 
present list, the first from the Union, will supplement those which 
have already appeared from America, Ceylon, and other countries. 
 Daedalea (Pers.) Fr. 
D. fuscospora, Lloyd. Old rotten log. 
D. Hobbsii, n. sp. (MS. name). Old log. . 
Favolus, Fr. 
Species of this genus were onty found on dead logs. The 
genus ia to oceur only in the more subtropical parts of 
the Union 
F. beasllicmais, Fr. 
F. dermoporus (Pers.) Lloyd. 
F. europaeus, /’r. 
F. Jacobaeus, Sacc. et Berl. This is the same as F. brasiliensis 
but with slightly smaller pores. In one collection the surface 
of the pileus was slightly tessellate and thus tended to 
connect this species with F. tessellatus, Mont. 
F. megaloporus (Mont.) Bres. 
F. spathulatus (Jungh.) Bres. 
Fomes (Fr.) Gill. 
F. applanatus (Pers.) Gill. On Acacia mollissima, Celtis 
kraussiana, Cunonia capensis, Curtisia faginea, Olea laurt- 
folia, Podocarpus sp., Pyrus communis, Rhus laevigata, Tricho- 
cladus sp. Under F. applanatus I include F. annularis, 
Lloyd, F. leucophaeus (Mont.) Cooke, F. vegetus (Fr.) 
Cooke F. australis (Fr.) Cooke. 
In the ‘South African Journal of Science,” Vol. xiv., 
p- 465, a rot of Olea laurifolia caused by this fungus was 
described.
