Agaric us speciosus Batt. 
Known as Polyporus sulphurus (Bull.) Fr. Polyporus 
cincinnatus Morg. is the same plant. Easily recognized by 
the color of the hymenium, which is a bright sulphur yellow. 
The pileus varies in color from yellow to reddish orange 
and specimens in the writer’s collection are faded to almost 
white. It frequently occurs as a parasite and is said to 
cause much damage to forest trees. It is always found 
much imbricated and often substipitate. Common from 
August until November, on stumps and trunks of oak, 
locust, etc.

Easily recognized by the very villous pileus, the dark 
colored hymenium, and the large angular pores, which are 
about 1 mm. in diameter. Most frequently found on poplar 
and cottonwood logs, but also on willow. Probably rare, at 
least in the southern part of the state.
