CONTEXT AND PORES WHITE OR PALE.
minute, rigid. Spores peculiar, oblong, truncate at base, 8 x 16 mic.,
hyaline.
It is a frequent plant in the East, Australia, Africa, India, Ceylon,
etc., but does not occur in the American tropics. It is a Polyporus
or perhaps a Trametes, and has been called both. It is usually of a
season only, and the old specimens turn black. Both Patouillard and
Berkeley discovered "new species," both based on old, effete conditions
of Polyporus ochroleucus. The spores are always abundant and
are peculiar, and are in reality white "Ganodermus" spores. There
are but two species known with such spores, Polyporus ochroleucus of
the East and Fomes Ohiensis of America. If the sections of polypores
are ever arranged strictly on the relationships of the species, these
two species will form a "genus" on the same character on which rests
the "genus" Ganodermus, excepting that the spores are not colored,
but hyaline. Both in its general appearance and the regularity of the
pores there is a resemblance between this plant and Polyporus (Ganodermus)
ochrolaccatus.

Polyporus ochroleucus.
Usually it is a Polyporus, but we have one collection which shows
distinct, annual layers, making it a "Fomes." The surface is usually
smooth, sometimes strongly rough, fibrillose, and sometimes it is
reddish, stained. The spores of weathered specimens become slightly
colored. It has a strong leaning toward "Ganodermus" in more than
one respect.

POLYPORUS VERSISPORUS. Pileus ungulate, dimidiate
(about 2x4x2 cm.) Surface with a reddish stain, hard, but no distinct
crust. Context pale, isabelline, hard. Pores minute, 8-10 mm.
long. Cystidia, none. Spores cylindrical, 4 x 8-10, hyaline, straight.
