 Irpex zonatus (from the type). 



The original specimens of Irpex Noharae were semiresupinate, 

 but this collection is all pileate. Irpex Noharae has such a close re- 

 semblance to Irpex zonatus, a misnamed plant from Ceylon (Fig. 852 

 photograph of the type) that there is a suspicion they are virtually 

 the same species. However, Irpex zonatus does not have in its type 

 form the peculiar teeth of the Japanese plant. Still they may be the 

 same thing. While hymenial configuration is the basis of fungus 

 classification, it is not always the test of a species. Polystictus pel- 

 lucidus (Myc. Notes, p. 554) is another plant that is quite close in 

 its leading features.
