SPORES HYALINE.
We found this not rare in Sweden. It grew on pine or spruce, and
usually was largely resupinate, sometimes with a narrow, reflexed
pileus, rarely with a well formed pileus as shown in Fries' Icones.
We have Polyporus fragilis also in the United States. Fries records
Polyporus fragilis and Polyporus mollis as equally common in Sweden,
but what distinction he made between them is difficult to find either in
his description or his Icones. We found but one similar plant in
Sweden, and from my observation, and Fries' description and figures,
I came to the conclusion that what he called Polyporus mollis was not
Persoon's plant, but was Polyporus fragilis. Quelet's description
would indicate that he also had only one plant under both names.
ILLUSTRATIONS. Fries' Icones t. 182, fig. 2, and also we believe fig. 3 (as mollis). Both
are more strongly pileate than the usual plant as we found it in Sweden. Sowerby's figure t. 387,
fig. 6, here cited, is some abnormality and has no possible relation here.
Compare fimbriporus, Keithii, sensibilis.
Fig. 659. Fig. 661.
Polyporus ursinus. Fig. 660, spores magnified. Fig. 661, Pore mouths of Polyporus fragilis (X6).
POLYPORUS URSINUS (Fig. 659). Pileus dimidiate (1x5x7
cm.), white, but turning reddish when bruised and on drying. Surface
strongly scrupose, tomentose, with rigid, tufted hairs, which have the
same color change as the flesh. Flesh white, soft when fresh, but
drying firm and hard. Pores medium large, sinuate, white, discolored
in drying. Spores (Fig. 660) narrow-piriform, tapering to the base,
2^x8-10.
This we collected growing on pine at Temagami, Ontario, August,
1907. We referred it, from the description, with which it agrees
exactly, to Polyporus Weinmanni of Europe, but we find the type of
the latter plant at Kew is quite different, being Polyporus mollis. We
think Professor Peck has collected the same plant (cfr. Rep. 31) and
also referred it to Polyporus Weinmanni.
POLYPORUS FISSILIS. Pileus soft, white, often largely resupinate
behind, 3-4 inches in diameter, an inch thick. Flesh soft,
