the pileus is often covered with a purplish tomentum which 
disappears with age. The pileus is generally rough and of a 
tawny color. The hymenium is darker in color than the 
pileus. The plant is generally found imbricated but is 
frequently found singly.

Known as Polyporus resinous Schrad. A handsome 
fungus with dark pileus. When young the plant is soft and 
fleshy and filled with a colored juice. As the plant gets 
older the pileus becomes harder. The pore surface is pallid 
and turns immediately to brown when touched. The 
pores are very minute. Common from October until 
December on dead deciduous logs.
