Fungi with Pores — Polyporaceae 



their attractive colours. They exhibit phosphorescence in early 

 stages of decay. The tubes are minute and short and of a 

 bright sulphur colour. Only the young plants should be used 

 for food.

Polvponis squamosus is found often on decayed ash trees and 

 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 



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

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

 colour a rich mahogany brown.
