Ptychogaster albus. Corda. Castle Fising. I cannot see why 
Fries should look upon this as a degeneration of 
Polyporus destructor. It consists of concen- 
tric layers, the more internal of which are dry 
and dusty, while the exterior are soft and 
moist. Unless I am greatly mistaken, tliis 
fungus grows by the development of fresh 
material from without ; in other words, I look 
upon the “fleshy peridium” as simply imma- 
ture parenchyma.
