SECTION AMAURODERMUS. 



The section Amaurodermus is quite close to the preceding section, but is 

 distinguished by large, globose, oval, colored spores, which usually have no 

 distinct apiculus. All are stipitate plants with usually dull (not laccate) surface 

 and often velutinate stems. Species rarely have smooth, laccate stems. Con- 

 text and hyphae are colored. All are plants of the warm countries, no species 

 being known in temperate regions. (Cfr. also p. 99). 



5. POLYPORUS. SPORES SMOOTH OR BUT SLIGHTLY 

 ROUGH. STEM SLENDER, USUALLY MESOPODAL. 



RUGOSUS. Pileus dark brown, rugulose with a dull, mat sur- 

 face. Stem olive brown with a dull, minutely velutinate surface. Con- 

 text pale cinnamon, when freshly cut it turns reddish. Pores small 

 with thin walls. Spores globose, smooth, 6-8 or 8-10. This is quite 

 a common species in the East and numerous specimens from Java and 

 Ceylon are at Kew. I have not seen the type but Nees gave a good 

 figure of it, and specimens from Ceylon (Thwaite, No. 728) exactly
