The pileus is a pallid wood color, corky, rugulose, uneven, without zones, becoming smooth; of the same color within as without; the margin in full-grown specimens thin, but in imperfectly developed specimens swollen and blunt.
The pores are at first round, then broken into contorted or gill-like labyrinthiform sinuses, with obtuse edges of the same color as the pileus, sometimes with a slight shade of pink.
They grow to be very large, from six to eight inches broad, being found on oak stumps and logs, though not as common in Ohio as D. ambigua. The specimen in Figure 357 were found in Massachusetts by Mrs. Blackford and photographed here.
Villose-strigose, cinereous with concolorous zones; hymenium with flexuous, winding, intricate, acute dissepiments, at length torn and toothed. The pores are whitish cinereous, sometimes fuscous; variable in thickness, color, and character of hymenium; sometimes with white margin; often imbricated and fuliginous when moist. Widely distributed over the states and found on nearly all deciduous trees.

Confragosa means broken, rough. The pileus is rather convex, corky, rough, slightly zonate, reddish-brown, unicolorous, somewhat of a rust-red within.
The pores are frequently round, like those of the Polyporus, but sometimes they are elongated into gills like the Lenzites; reddish-brown.
I have seen quite old specimens that were very difficult to distinguish from some of the forms of Lenzites. The young plants resemble very closely Trametes rubescens. It grows on Cratægus, willow and sometimes on other trees, and is widely distributed. The specimen in Figure 358 was found in Massachusetts by Mrs. Blackford, and photographed in my study.
Favolus is a diminutive of _favus_, honey-comb.
The hymenium is alveolate, radiating, formed of the densely irregularly uniting gills; elongated, diamond-shaped. Spores white. Semicircular in outline, somewhat stipitate.
[Illustration: Figure 359.--Favolus Canadensis.]
The pileus is fleshy, tough, thin, kidney-form, fibrillose, scaly, tawny, becoming pale and smooth.
The pores or alveoli are angular elongated, white at first, then straw-color.
