SPORES HYALINE.
first took it to be this species. Same shape, size, context, and general
coloration, though darker. On comparison, the pores are more minute,
but the main difference is in the spores, which are entirely of a different
type, shape, and size.

D. Pileus a hollow globe, bearing the pores on upper side of the interior.

POLYPORUS VOLVATUS (Fig. 652). Pileus a hollow globe,
with an opening behind, bearing the pores on the upper side of the
interior. Sessile or with a false stipe. Surface smooth, with a thin
crust, usually the upper portion only colored with a reddish brown,
resinous stain. Pores small, slightly darker than the context, and with
darker brown mouths. Spores oblong, 4x12, hyaline, smooth.
This most curious Polyporus occurs on spruce, both in our
eastern, western, and northern States. It seems to be absent from the
South. It is found also in Japan and China, but is unknown from
Europe. It proceeds from perforations of the bark caused by a beetle,
and Mr. Kawamura, of Japan, writes me that in Japan it is usually
stipitate, the stipe penetrating the hole. We think it will prove that
this is a false stipe of a mycelial nature, something like the mycelial
core that occurs in Polyporus rheades. As we have in a previous
publication given a history of the mistakes that were made in naming
the plant, we shall not repeat them here.
