names as Trametes populina, Polyporus vulpinus (in error) and 

 Daedalea Schulzeri. From Cuba it was called Polyporus pallido- 

 cervinus, changed to pallidofulvellus, a useless change, as the Cuban 

 plant is the same as our common American plant. In Africa it ap-

 feel that it should have a distinctive name.

 FROM P. VAN DE BIJL, SOUTH 

 AFRICA. This is an ambiguous, 

 tropical genus, lying between Hyd- 

 naceae and Polyporaceae. It is 

 classed in the former in Saccardo, 

 but the hymenium is sometimes 

 decidedly polyporoid, as in a species 

 recently named from the Philip- 

 The surface is covered with minute granules, 



visible to the eye. The genus was originally from Cuba and embraced 

 four species (all probably the same), the different hymenial aspects be- 

 ing due probably to different positions of growth. I am not sure that 

 the South African plant is the same as the Cuban. It should be com- 

 pared under the microscope. But to the eye it is the same. On sec-
