3. F. fraxinophilus Peck ex Sacc. Syll. Fung. 6:172. 1888. 
Polyporus fraxinophilus Peck, Ann. Rept. N. Y. State Mus. 
35:136. 1882. 
Plants perennial, sessile or effused-reflexed, often imbricate; 
pileus dimidiate, convex to compressed-ungulate, 2-25 x 3.5-40 
x1.5-10 cm., woody, white at first, becoming blackish and 
often somewhat rimose with age, not encrusted, soon glabrous, 
concentrically sulcate, margin thick, obtuse or acute; context 
white to cinnamon wood-color, corky or woody, 0.5-1 сіп. or 
more thick; tubes 2-3 mm. long, indistinctly stratified in many 
layers, the mouths white to cinereous or yellowish, circular, 
averaging 2-3 to a mm., the walls thick and entire; spores white, 
smooth, ellipsoid to ovoid or pyriform, 5-6.3 x 7.3-8 y. 
Growing only on living trunks of Fraxinus. Common. 
In habitat the species corresponds closely to F. fraxineus 
Bull. ex Cooke, from which it differs in the entire absence of any 
rosy or reddish colors and in being always perennial. Ап 
excellent illustration is given by Hard (Mushrooms f. 350). 
4. Е. connatus Weinm. ex Gill. Champ. Fr. т: 684. 1878. 
Polyporus connatus Weinm. Fl. Ross. 332. 1836. P. con- 
natus Fries, Epicr. Syst. Мус. 472. 1838. 
Plants perennial, sessile or effused-reflexed, sometimes imbri- 
cate; pileus dimidiate, convex, 2-10 x 3-15 х 0.5-4 ст., corky 
when fresh, somewhat woody when dry, whitish, cinereous, 
or slightly yellowish, sometimes blackish toward the base, not 
encrusted, velvety-tomentose to glabrous, usually azonate, 
margin thick, acute or obtuse; context white or pallid, punky 
to soft corky, 0.3-1 cm. thick; tubes 1.5-5 mm. long, distinctly 
stratified, the different strata separated from each other by 
a thin layer of context, the mouths whitish to yellowish, glis- 
tening, angular, averaging 4-5 to a mm., the walls entire to 
slightly dentate; spores (teste Bresadola) white, globose, 3-4 и 
in diameter. 
Growing on living deciduous trees, more often at the bases 
of species of Acer, and frequently covered with moss. Common. 
The distinguishing characters are the habitat, the layers 
of context interposed between successive layers of tubes, and 
the glistening mouths of the tubes. In but one other species 
of Fomes do we find the second character developed and that
