SPORES COLORED.
Sweden it grows on poplar and oak. The pileus on oak is usually solitary, large,
subglobose. On Populus it is imbricate. It is the same fungus, but the difference
is due, Mr. Long tells us, to the resistance of the different wood. On both hosts it
is a heart rot, but it has no power to attack the sap wood of the oak, hence the fruit
is developed from some accidental opening like a knot hole or a broken branch, and
from a small base. Poplar is a softer wood, and the fungus destroys the sap wood,
and the fruit develops from a broad base.
In Germany Hartig illustrated Polyporus rheades as Polyporus dryadeus, and
his figure is so characteristic, and the account so plain, that the misname is evident.
It is probably the basis of Polyporus rheades of German works, though both species
undoubtedly grow there. We have found Polyporus rheades' at Berlin. In France
it does not seem to have been recognized since Persoon's day, until Patouilferd called
it Polyporus tamaricis. Quelet may have had it right. In America we only know
the oak form which Berkeley called Polyporus dryophilus. That also is rare, but
more frequent in our Southwest. Morgan collected it, and Long recently had quite
an article on it under Berkeley's name. Polyporus dryophilus. We do not think
it advisable to use this American name when the plant has several names in Europe,
and dryophilus is likely to be confused with Polyporus dryadeus, an entirely different
species.
SPECIMENS. We have the following collections, and have indicated in parentheses the names
they were originally labeled. Washington, W. H. Long (dryophilus); Ohio, G. D. Smith (dryophilus),

Polyporus Farlowii.
POLYPORUS FARLOWII (Fig. 697). Pileus applanate, wavy.
Surface strongly hispid, with suberect, brown hairs. Context hard,
ferruginous, brown (antique brown), fibrillose. Pores small, round,
firm, concolorous. Setae abundant, straight, projecting 30 mic.
Spores colored, elliptical, 2^ x 4>-5.
The type at Kew was collected in Arizona and, according to the
label, sent by Farlow to Cooke, who determined it as Polyporus
