SECTION OVINUS. 



MYLITTAE. Sclerotium, the well known "native bread" of Aus-

 the fruit, but a photograph of a sclerotium with the 1'olyporus is at 

 the British Museum.

OVINUS. White. Pores small. Spores 3^-4. Common in 

 Sweden and is also found in Alpine regions of central Europe. Its 

 record in the United States is not certain. 



LEUCOMELAS. Pileus fuliginous. Pores pale. Spores tuber- 

 cular. Rare in Europe. Not known from the United States.

CAERULIPORUS. Pileus and pores bright blue when in prime. 

 Brown when dry. Very rare in the United States. 



POLITUS. Color dark reddish. Very rare in Europe. Only known from 

 Fries' Icones and a specimen at Kew. Possibly it is a small mesopodial form 

 of confluens.
