This is the most frequent species in Africa, though it occurs over most 

 of the territory where similar forms occur. It was probably first published 

 by Ehrenberg as Polyporus Katui and a good figure was given of it. Fries 

 named it xanthopus in the same year. I do not know which was prior, but 

 Fries had more influence and established his name, giving Ehrenberg's as a 

 synonym. 3 Then Persoon published it, from Rawak, as Polyporus saccatus 

 and also gave a good figure of it. His specimen is at Paris. It is needless to 

 say that Persoon's name was soon dumped into synonymy. 



Forms.

 thick yellow stem and a smooth, dark bay pileus. It can only !>_ held as a 

 dark form of xanthopus.

 zoned, covered with a fine. soft, don-ny. relrcty pubescence. 



3 The type of Katui is in good condition at Berlin. No type of xanthopus -xi--t>. thouiih 

 there are several specimens of Fries' naming.
