a synonym for this species. Recently Bresadola, in working over
the Java fungi at Leiden, referred to Ganodermus Cochlear, a plant
that seems to be common in Java and which we have received from
Dr. Konigsberger (cfr. Stip. Polyporoids, page 103). We accepted the
name Cochlear for this species, although we do not believe it is the
same as Nees illustrated particularly as to the stipe.
The other species that Nees named Polyporus gibbosus, Fries
(from the picture) considered a valid species, and it therefore passed
into our literature and is compiled in Saccardo (Vol. 6, p. 156). I can
not see any marked difference between Nees' figure of Cochlear and
gibbosus, and I believe it will develop that both are the same plant.
I have received a plant from C. B. Ussher, Java (Fig. 627) that appears
to me to be exactly the same as Nees illustrated under these names,
and I have also young specimens from Dr. Konigsberger. I shall
use the name Ganodermus gibbosus for this plant and in this sense
quite different from the plant Ganodermus Cochlear in the sense of
Bresadola.
Ganodermus gibbosus in this sense has a very peculiar lateral,
gibbose stipe (see Fig. 627) as characteristically shown in Nees'
figure. With the exception of the stipe, however, and the fact that
the pores, are not stratose, in all its "structural" characters, viz.,
surface, color, crust, context color, pores and pore mouths, it corresponds
to Fomes leucophaeus. The spores (in this specimen) are
smaller (not over 8 mic. long) than those of the American Fomes
to the exact
leucophaeus, but I do not attach much importance
size of spores. It could be considered, of course, an annual, stipitate
form of Fomes leucophaeus, but in the United States, where Fomes
leucophaeus is the most common species we have, it never takes a
normal stipitate form. Sometimes Fomes leucophaeus takes a false
stipe when growing under abnormal conditions, but I believe that
the stipe of Polyporus gibbosus is a normal feature of the plant.
The specimens I have are Polyporus, but it may be a Fomes when
it gets older. It is quite close to Fomes testaceus of the Synopsis
Fomes which, however, has always a peculiar brown surface color,
and a regular stipe.
