height from the ground, for the tree is always infected originally
through some wound, like a broken branch. I have never noticed it
on trunks in woods, but have collected it on trunks in park at Upsala
and around Berlin, where the trunks are more liable to injuries. It is
not often found on young trees, because the wounds on young, vigorous
trees are more quickly protected by a coating of turpentine.
In Europe, in addition to the Scotch pine (Pinus sylvestris), which
is its most common host, it occurs also on spruce, larch and the silver
fir. In this country on various species of coniferous trees.
There is a tradition handed down from Fries that the pores do
not form distinct strata "sed nulla strata distincta," but that is a
mistake. The strata are quite distinct and the plant is a Fomes.
The young pores are lined with a yellowish hymenium which is noticeable
to the eye. The old pores fill up with tissue the same color as
the context, hence might be taken for the context. The young growing
tissue is yellow, but it soon changes to brown, and rarely specimens
are seen with any part yellow.

is supposed to mean "yellow spores," and not very applicable to a plant like this (or several that he
includes) with hyaline spores.
Specimens. Many from Europe and United States and Canada. None from foreign countries.
Compare Fomes odoraius in Section 69, page 273.
The following two plants we consider here from their evident close relationship
to Fomes pini. They are classed as Trametes, which they are technically, I believe,
for I do not know that they ever form layers of Still I think
pores.
they are better
Fomes, from their woody texture and relationship, but I do not propose to change
their names.
