Piptoporus suberosus (L.) Murrill 



(Polyporus betulinus Fr.) 



The white birch polyporus is common throughout the northern 

 states on Betula papyrifera, B. populifolia, B. 

 lutea and more rarely on B . 1 e n t a . It has been known as 

 far south as New Jersey and Iowa. It was recently collected, how- 

 ever, on Yellow Birch, near Sunburst, Haywood county, North 

 Carolina, at an altitude of over 5000 feet, on the slopes of Richland 

 Balsam, next to Mitchell, the highest mountain in the state (H. D. 

 House, No. 13.10. June 10, 1913). 



Daedalea quercina (L.) Pers. 



This is a characteristic fungus on logs and stumps of the oak 

 in European forests where it frequently attains a very large size. 

 In America, it seems to be both smaller, as a rule, and less abundant. 

 Small but excellent specimens were collected on stumps of white 

 oak at Sylvan Beach, Oneida county (House, no. 13.37. July 22, 



1913).
