SPORES COLORED, TRUNCATE. 



POLYPORUS NIGROCRUSTOSUS. Pileus applanate, with a dull, black, 

 smooth crust. Context very thin, pale isabelline. Pores minute (1-1X cm - long), 

 pale umber, with concolorous mouths. Spores 10 x. 12, oval, punctate, the hyaline 

 membrane but little prolonged at base and rarely truncate. 



We propose this name for a specimen received from H. Val. Ryan, Dodabetta, 

 India, which we are unable to refer to any of the previous species. When received, 

 we referred it to Fomes nigrolaccatus, but this specimen is an evident Polyporus 

 (not Fomes). 



SECTION 104. POLYPORUS (AMAURODERMUS). 



The section Amaurodermus of Polyporus are mostly stipitate (cfr. Stipitate 

 Polyporoids, page 110), and the only sessile one to my notice is not certain. 



POLYPORUS DAHLI I. Pileus sessile (about 4x3x2 cm.). Surface dark, 

 reddish brown, somewhat zonate, dull. Context scanty. Pores regular, long, al- 

 most reaching crust. Spores globose, smooth, 8 mic., deeply colored. 



This is imperfectly known from one specimen at Berlin from New Guinea. It 

 was named in mss. by Hennings, but not published, as far as I know. To the eye, 

 it resembles a Ganodermus, but its spores are of Amaurodermus. All others with 

 similar spores are stipitate, and while this specimen is sessile, it would not be safe 

 to conclude that this is a character of the species.
