 sometimes on others. The cap has a thick lateral dark stem and 

 is pale yellow tinged with brown, and covered with dark scales. 

 It is reported to have been found seven feet in circumference, 

 with a weight of forty-two pounds, and that it attained this 

 growth in the short time of four weeks.

Polyporus lucidus has a lateral stem which, with all but the 

 margin of the cap, is highly polished, as if varnished, and is in
