inches in diameter. It is the only abundant, white Polyporus one

Forms.
POLYPORUS SPATHULATUS.-The common Polyporus borealis is a thin,
dimidiate plant, but it has a tendency to form behind a reduced base, or a "short
lateral stipe, as Fries notes it. He named this form as above.
POLYPORUS LAPPONICUS.-This was named by Romell from a single
specimen on Abies in Lapland. It is similar to Polyporus borealis, and was so taken
by Romell when collected. The spores, oblong, 3-4 x 8-12, are quite different We
have seen no specimens.
B. Pores small, round.

Polyporus occidentalis.
POLYPORUS OCCIDENTALIS (Fig. 671). Pileus sessile,
white, with soft, fibrillose surface. Context light weight, soft, friable
near the surface, firmer below. Pores white, small, 2-3 to mm.
Quite similar to Polyporus obtusus in the color and soft, lightweight
flesh, it differs markedly in having small pores. It is quite a
rare plant, and but few collections are at New York Gardens. It
occurs on beech. We have only one collection, from S. H. Burnham,
New York.
POLYPORUS PELLES. Pileus dimidiate or from a reduced
base. Surface soft, densely hairy, dark brown. Flesh (of dried
specimens) hard below, softer above, and resolved into the dense hairy
surface; white (probably) when fresh, but discolored, fuliginous in
specimen. Pores minute, round. Spores elliptical, 3^4x5^, hyaline.
Based on a specimen (No. 8) from E. Jarvis, Queensland, Australia.
The soft, hairy surface is comparable to the fur of some
animal. The plant is evidently related to Polyporus rufescens (but
