SECTION PETALOIDES. 



found but surely white. As to its context, color, velutinate surface and 

 colored setae this corresponds to Fomes pomaceus, but the presence of a 

 stipe removes it from all species with similar structure. Specimen col- 

 lected by S. Kawamura, Japan. Referred to Hennings' species on the 

 description only as there was no type in the cover when I visited Berlin. 



18. GRAMMOCEPHALUS GROUP. PILEUS MARKED 

 WITH RAISED LINES. 



A varying assortment of plants that could be referred to one species, and still have marked differ- 

 ences. Those with large pores run into Favolus. 



a. PORES SMALL. SETAE NONE. 



GRAMMOCEPHALUS (Fig. 437). The type form from the 

 Philippines is orbicular or reniform, reddish brown with medium 

 small pores. This is quite a frequent plant in several countries and 

 seems to vary, so it is hard to decide what to consider as its varieties.

 Petaloides grammocephalus. 



PERVERSUS (Fig. 438). Only a variety of grammocephalus, more spathu- 

 late and of darker color. Determined, published, and distributed (Copeland, 

 No. 18) as Polyporus coracinus which, teste the description, viz. : with colored 

 setae, and teste Bresadola, is quite a different plant. I have not seen coracinus 

 except this evidently mis-named specimen. This form of grammocephalus is 

 common in Samoa. 



CAYENNENSIS (Fig. 440). The American form from South America. 

 Pores minute. Color pale, form spathulate.
