CONTEXT AND PORES WHITE OR PALE.
E. Trametes.
The following three species are (doubtfully) better classed in Trametes on account of their
" punky" flesh, but are apt to be sought in this section of Polyporus.
TRAMETES SUAVEOLENS. Pileus usually applanate, about
an inch thick. White when growing. Surface anoderm, hard, but
minutely pubescent and soft to the touch. Context white, dry, corkypunky.
Pores firm, rigid, medium, round. Spores 3-4x10-12,
cylindrical, curved.
It is a common species both in Europe and the United States,
always on willow. It is quite fragrant when fresh, odor of anise, and
is easily recognized. When in its prime it is a pure white plant, but
old and wintered specimens turn dark. The surface is soft, pubescent,
and in northern Europe the pubescence is longer and might wr ell be
described as villose. Fries' type, in the British Museum, is of this
nature. We do not seem to have this villose form in the United
States.
ILLUSTRATIONS. Sowerby, 228, pores larger than usual; Boudier, 163, drawn from a discolored
specimen; Gillet, 473, the best. Many others.
SPECIMENS. Many, from United States and Europe.
TRAMETES ROBINIOPHILA (Fig. 653). Pileus ungulate,
white, 2-3 inches thick, with dull, white, mat surface. Context white,
drying soft and punky. Pores minute, round, 4-6 mm. deep, white,
drying isabelline or darker than the context. Spores subglobose, 7-8
mic., hyaline, transparent, with large guttae.
The locust (Robinia pseudacacia) is the only host that bears this
species. It is common in the Middle West. Usually it grows from
decayed parts of standing trees, and is usually solitary. It has been
known for many years, and was the basis of Polyporus salignus of
Morgan's record. Recently Murrill discovered that it was a new
species, and named it as above. It is a question whether it is a Polyporus
or a Trametes. The punky context is much softer but similar
to that of Trametes suaveolens, and for that reason it may be classed
as Trametes. We do not know it excepting from the United States.
SPECIMENS. Many from the United States, all from locust.
TRAMETES CUBENSIS. Pileus thin, rigid, sessile. Surface
smooth, no distinct crust, white, usually with a reddish blotch or stain
at the base. Context white, rigid, punky, becoming dark with age.
Pores minute, round, rigid. Spores we have never found.
This is a frequent species in the American tropics and southern
Florida, and a very peculiar one. When growing it is white, and it dries
white, but after some months on herbarium specimens there comes a
red stain on the pileus and the plants turn dark, finally getting almost
black. the stain
Perhaps comes on plants in situ, but we collected it
white in Florida and did not recognize it until after some months
