Figure 348.—Fomes pinicola.
Pinicola means dwelling on pine. It is found on dead pine, spruce, balsam, and other conifers. It resembles Fomes leucophæus but is somewhat stouter and does not have as hard and firm a crust. The young growth is at the margin, and is whitish or tinged with yellow, while the old zones are reddish. The tube surface is whitish-yellow or yellowish. This is frequently called Polyporus pinicolus. (Swartz.) Fr.

Figure 349.—Fomes igniarius.
This is rather a common species in our state; black or brownish-black in color, somewhat triangular in shape, and frequently hoof-shaped. The zones indicating the yearly growth are plainly marked, and the tubes are quite long and of a dark brown color. Their growth is rather slow, and it requires years to produce some of the moderate sized specimens. Prof. Atkinson of Cornell University found a specimen which he believed to be over 80 years old.
This is called by many authors Polyporus igniarius (L.), Fr. Murrill calls it Pyropolyporus igniarius. This plant is widely distributed over the United States, and is met frequently in every wood in Ohio.
