texture and context color, the plant is very close to Fomes robustus
of Europe (cfr. page 242), which never in Europe nor in other countries,
as far as I have noted, has this peculiar annular, sulcate surface.
The spores are much smaller than those of Fomes robustus, and^the
plant has no setae.

Fomes Yasudai.
FOMES ODORATUS. Pileus ungulate, thick, hard. Surface
dull, minutely villose, uneven by the overlapping growths. Context
hazel brown. Pores small to medium, with thick walls, with the
hymenium lining the pores lighter than the context. Setae none.
Spores 4 x 8-10, cylindrical, hyaline. Odor when fresh strong, fragrant.
This is not a rare plant in Europe on spruce, but it does not
occur in the United States. Our records are all in error. It is quite
close to Fomes pini in shape, size and texture, in its context color,
the contrast between the color of the pore lining and the context, and
in a less degree in its odor, for Fomes pini is said to have a "weak
odor" when fresh. The pores are smaller, the surface is different,
but the most marked differences are the absence of setae on the hymenium,
and the spores. When fresh the growing pores are bright
