SPORES HYALINE.
SPECIMENS. Colorado, C. H. Demetrio, E. Bethel, E. Bartholomew, L. O. Overholts; Montana,
James R. Weir; Utah, A. O. Garrett. Since this has been in type, we have received a specimen
from Dr. C. H. Kauffman, collected in Michigan.
POLYPORUS AURANTIACUS. Pileus orange with rough,
fibrillose surface, no crust. Context bright orange, soft, spongy, thin.
Pores medium, soft, irregular, with unequal mouths, disposed to split.
Color of tissue, pale orange. Spores hyaline, 3x5, smooth.
This is a rather rare plant in the northern United States, usually
on hemlock wood. We have collections, however, on birch and maple.
It is well named from its bright, orange color. It occurs in Finland,
but is apparently very rare in Europe, for all the specimens in the
museums are Karsten's exsiccatae, No. 311, under the nameTrametes
fibrillosus. This is a prior name, but there is something crooked in its
history. Karsten described the plant in 1859 (not 1882, as misstated)
as having context "fulvus," and admitted (1876) that it was the same
as Polyporus vulpinus, a brown species. He distributed (Exsic. 311)
an orange plant under this name, but whether he substituted another
species or whether he described a bright, orange plant as being "dark
ferruginous, fulvus," we do not know; but in neither case has his
work much claim.
It occurs also in Japan. A collection from Ikeno was misreferred
by Hennings to Polyporus Shiraianus. This is the only Japanese collection
known.
SPECIMENS. We have collections from Massachusetts, Idaho, Vermont, Newfoundland,
. Michigan, Canada, and Washington.
Compare crocicolor, fibrillosus.
SECTION 93. CONTEXT VINACEOUS OR PURPLE.
POLYPORUS DURUS Pileus sessile, thin (4x6x1 cm.),
drying hard and rigid, and usually incurved. Color of dried specimens
very dark, almost black with purplish tinge. Surface smooth, dull, no
distinct crust. Context hard, rigid, 2-4 mm., dark brown with faint
purplish tinge. Pores minute, hard, 3-5 mm. long, with dark, atropurpureus
mouths and tissue. Hymenial cells hyaline. Spores
globose, hyaline, 3 mic.
This is not an unusual species in the East, but does not occur in
American tropics. We have seen it from Africa, Java, Philippines,
Australia, Ceylon. We made one abundant collection in Samoa. The
color of the dried plant, dull, violet black of Ridgway, would ordinarily
be called atropurpureus. We do not remember the color of the fresh
plant, but our impression is that it was more brown. We do remember
that we associated it with Polyporus gilvus, which we would not
have done had the color been that of the dried specimens now. Junghuhn
named it from Java. Berkeley called it Polyporus cartilagineus
(a senseless name) and also Polyporus Testudo.
SPECIMENS. Madagascar, Henri Perrier de la Bathie; Samoa, C. G. L.; Philippines, E. D.
Merrill; Ceylon, T. Petch.
Compare cartilagineus, Testudo, also Pomes melanoporoides, and Fomes ponderosus.
