SECTION PETALOIDES 18 C. 



It develops that there are several polyporoids with very peculiar setae, as il- 

 lustrated in Figures 441 and 442. The species considered in this pamphlet are 

 cinnamomea-squamosus (p. 138) russiceps (p. 138), megaloporus (p. 138), and co- 

 racinus (p. 146, unknown to me). In addition, Favolus princeps of Cuba has these 

 same peculiar cystidia and perhaps other species of Favolus. Bresadola is inclined 

 to refer them all to one species. They seem different to me in macroscopic characters, 

 though the microscopic characters are quite close. 



SECTION MERISMUS 28. 



DISPANSUS (Fig. 498). Pileus submerismatoid, appearing to 

 be borne irregular from a common base. Surface smooth. Color 

 yellowish. Pores small, colored, reddish brown (about same color 

 as those of Polyporus rutilans). Context thin, the pores almost 

 reaching the cuticle. Spores abundant, globose, smooth, 3^-4 mic., 

 hyaline.

This is quite similar in its habits to Polyporus Wynnei of Europe, 

 which is the only plant to my knowledge that it suggests. Both are 

 doubtfully included in the section Merismus. The Japanese plant 

 is abundantly different from the European in its colored pores, and 

 spore shape. We have no plant in the .United States that approaches 

 either. 



SECTION MERISMUS 29. 



FIMBRIATUS. The common plant in the American tropics which has the 

 peculiar hymenial configuration, as shown in Figure 453, has been classed in six 

 different genera. We consider it as a degenerate type of a polyporoid. We refer 

 it to fimbriatus following Bresadola, though the type specimen of fimbriatus at 

 Upsala has perfect pores. Otherwise it seems to be the same to us.
