A very rare plant in this state and is said to grow on oak 

 and chestnut wood. 



49. Laetiporus speciosus (Batt.) Murrill, Bull. Torr. Club 



31 : 007. 1904. 

 Agaricus 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, 

 locvist, etc.

50. Cerrenella farinacea (Fr.) Murrill, N. Am. Flora 9 : 74. 1907.

 more common farther south. On dead deciduous wood. 



51. Coriolopsis rigida (Berk. & Mont.) Murrill, N. Am. Flora 



9 : 75. 1907. 

 Trametes rigida Berk. & Mont. 



A semi-resupinate form found on dead wood, especially of 

 the sugar-maple. The pileus is never more than 2 cm. in 

 width, and is often entirely wanting. The hyinenium is 

 wood-colored. Common. 



52. Funalia stuppea (Berk.) Murrill. Bull. Torr. Club 32 : 356.

 Trametes stiippeus Berk. 



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.
