CONTEXT AND PORES COLORED.
on our last trip to Europe. Fries evidently (as he states) did not know the plant,
but he misreferred here a figure of Bolton and apparently drew his description from
Bolton's figure. In that sense it was probably Fomes pomaceus. and has so been
referred as a synonym by Quelet and Bresadola. Polyporus cinnamomeus has nothing
in common with Fomes pomaceus, but is a species of Polyporus, otherwise unknown
to me. It suggests to me only Polyporus valenzuelianus, and the pileus surface
is of the same reddish color. It is evidently a most rare species of Europe, and
has not been found since Trog, eighty years ago.
ILLUSTRATIONS. None. Bolton's figure, here referred by Fries with doubt, has no resemblance
to it.
Fig. 675.
Polyporus zonalis.
POLYPORUS ZONALIS (Fig. 675). Pileus thin (4-6 mm.),
rigid, drying hard, incurved. Surface reddish brown, with narrow,
concentric, raised zones. Context thin, hard, pale ochraceous. Pores
minute, 3-4 mm. long; when old, brown, but my impression is that
they are orange when fresh. Spores abundant, globose, 4-5 mic.,
hyaline, smooth.
This is a common species throughout the tropical world. It was
named from Koenig's specimen from Ceylon, type at British Museum.
The greater part of the abundant specimens in the museums, both
from American tropics and the East, are evidently the same, though
aberrant forms are found in the American tropics. Fomes lignosus,
also a common species in the tropics, is very much like this in its (usual)
Polyporus form. We have trouble in distinguishing them. Same
general colors and pileus surface. The pores in Polyporus lignosus
fade out in the older parts, but retain a uniform color in Polyporus
zonalis. There are always abundant spores found in Polyporus zonalis.
We have never found spores in Polyporus lignosus. We have a collection
from Ceylon with more adustus pores than usual. Also collections
from Brazil with pileus not so strongly zoned. Polyporus
zonalis in the American tropics grades into the next.
