curious that we do not know this type of Irpex teeth excepting in 

 Japan.

Irpex lamelliformis. 



Irpex lamelliformis has the teeth arranged in lines (lamelliform), 

 in fact it might be classed as an irpicoid Lenzites. The whole aspect 

 of the plant and coloration of the teeth, and the microscopic details 

 remind one of Polystictus abietinus. There is an intimate relation 

 between these two species, although the hymenial configuration is 

 so different. 



Irpex Noharae (Fig. 1074) to which we formerly referred it, 

 differs in texture and surface, and coloration. The surface is more 

 pubescent, on the order of Daedalea unicolor. The teeth are more 

 rudimentary. It is evidently rare in Japan, for only known from the 

 type collection.
