Trametes ohiensis Berk. 
This little fungus (very small for the genus Fomes) is 
found abundantly on fence posts, rails, pickets, dead spots 
on certain deciduous trees, and on old structural timber. 
The pileus becomes black only at the base, and the tubes are 
longer than in F. scutellatus (Schw.) Cooke with which it 
is often confused. The hymenium is white and the walls of 
the tubes are almost as thick as the diameter of the mouths. 
68. Fomes scutellatus (Schw.) Cooke, Grevillea 14 : 19. 1885. 
Poly poms scutellatus Schw. 
Rare, growing only on the alder in this state. 
69. Fomes fraxinophilus (Peck) Sacc. Syll. Fung. 6 : 172. 1888. 
Polyporus fraxinophilus Peck. 
This species is found on species of Fraxinus and is a 
wound parasite. It grows to be very large, specimens 
having been brought in which were 30 cm. across. It is 
perennial and most commonly grows from 30 to 40 feet 
above the ground. The pileus is at first white but becomes 
black and rimose with age. Common.
