CONTEXT WHITE OR PALE. PORES COLORED.
In pine regions of Europe this is a frequent plant. It is noted
for the various shades of color the pores assume. The gelatinous
nature of the plant gives the pores a waxy appearance, by which the
species can be recognized even when dry. In the United States it is
rare, in the East. Schweinitz's record is an error, but Berkeley-
Ravenel's record is correct. We have fine typical specimens from
Idaho, Weir.
In olden times Link named the plant Boletus epigeus, according
to his specimen, but it does not seem to have gotten into print. Fries
called it Polyporus amorphus. Persoon states (truly) that it is no
more amorphous than any other species, and would have changed the
name to Polyporus aureolus, which, of course, Fries would not accept.
He changed Persoon's names whenever it suited his fancy, but he
would not stand for his own names being changed. We believe Polyporus
amorphus never occurs except in connection with pine, and it
often grows over pine needles.
ILLUSTRATION'S. Gillet, very good, form with yellow pores. Sturm, fasc. 27, t. 12, best
form with rosy pores (called Polyporus roseo-poris). Sowerby, 423, no doubt correct, but poor.
SPECIMENS. Europe, a number; United States (where it is extremely rare): Idaho, James R
Weir, three good collections; Michigan, C. H. Kauffman; Eastern States, F. H. Ames, Miss A. Hibbard.
These four collectors (and Ravenel) are all that have ever been found in the United States. (It
is not included in N. A. F.) Japan, A. Yasuda.

SECTION 91. CONTEXT ISABELLINE OR YELLOW
POLYPORUS CROCEUS. Pileus bright yellow when in its
prime, sessile, dimidiate, sometimes large (5-15 x 10-25 x 1-3 cm.)
Surface dull, concolorous, minutely velvety when young. Flesh concolorous,
drying hard, and discolored. Pores concolorous, medium,
small, irregular, drying hard, resinous, darker color than the context.
Spores oval, 3 x 4-4>, smooth.
WT hen in its prime, this is the most showy Polyporus that grows;
nevertheless there has never been a colored plate made of it. It is
rather rare in Europe, always on oak, and has a preference for growing
in hollow oaks. In America it is larger and more common, often on
