always stalked or occurs on much-decayed stumps. At first, for a
few days, it is white, then takes pale brown, and finally chocolate
brown. The stalk is practically black and the hymenium pallid. It
is white only at first, and the color change to brown is assumed but
slowly."
A piece of the pileus, on comparison, seems the same as Polyporus
Talpae of American tropics (cfr. Myc. Notes, Polyporoid Issue,
page 36), and when I first received it, I referred it to that species.
The specimen just received, however (Fig. 771 much reduced), shows
it is mesopodial, and it must be classed in section Ovinus. Polyporus
Talpae (cfr. figure 360 loc. cited) is merismatoid, and goes in the
Merismus section. Notwithstanding this material difference, I have
a suspicion that they are about the same species. The pores of
Polyporus mesotalpae are certainly smooth. I have recorded the
spores of Polyporus Talpae "minutely rough." This record was
made from the original specimen at Kew. I have two collections
from tropical America, but find no spores in either. Excepting this
slight spore difference, which is not sure, and its different stipe insertion,
I can find no difference between the two species.
MYCOCITRUS AURANTIUM (Fig. 772), FROM P. PIO
BUCK, BRAZIL. There is great merit in Alfred Moeller's work
on Brazilian fungi in several respects. It is systematic, it is well
illustrated, it is accu-
rate, and it is practical
to determine plants from
it. That can be said of
very few works that
have been written on
mycology. When Moeller's
work appeared, it
made known a new field
of Hypocreaceae. They
are mostly large plants,
several inches in diameter,
evidently very conspicuous
when they
grow, and .which seem
never to have been collected
before. Several
new genera are proposed
and good ones,
too, apparently Mycocitrus,
Mycomalus, Ascopolyporus,
that grew
encircling living
branches. Apparently
they are epiphytes,
which upsets the whole
idea of the mode of life
