POLYPORUS (AMAURODERMUS) PAPILLATUS (Fig. 773),
FROM REV. C. TORREND, BRAZIL. Pleuropodial. Pileus 6 x 10
cm., 6 mm. thick, with dull (not laccate), rugulose, radiate surface,
brown, with tubercular, uneven, dull surface. Context and pore
tissue concolorous, hard, dark cinnamon brown. Pores minute, with
papillate, brown mouths. Spores globose,
or slightly piriform, 10 mic., palecolored,
smooth.
The pores seem to be developed in
areas, and the papillate mouths (Fig.
774 enlarged) are quite curious. In fact,
a similar appearance led Berkeley to
classify Polyporus Sprucei as Porothelium
(sic). (Cfr. Stipitate Polyporoids,
p. 110, fig. 404.)
This belongs to section 7 of the
Stipitate Polyporoids, and we believe it
is only a form of Polyporus Chaperi,
differing in its rugulose, striate (not
zoned) pileus, its papillate pore mouths,
and its stem, solid, not having sterile branches. When I first investigated
the subject, there was but one specimen of Polyporus Chaperi
known, which was at Paris. It came from Cuba. (Cfr. Stipitate
Polyporoids, Fig. 406.) Then I got a specimen from Gustavo Peckolt,
Brazil, agreeing exactly with the type in everything. Then I saw in
Ellis' herbarium a specimen from Smith, Nicaragua, which had a
lateral stipe, but every other feature exactly the same as Polyporus
Chaperi and surely same species. It was named Polyporus avellaneus
by Murrill. Then I so referred a specimen (sent without stipe No. 44)
from Rev. C. Torrend, Brazil. There is evidence of its having had a
lateral stipe. Then I got this specimen, which, while it differs from
the four previous specimens in several
believe it is only a form of Chaperi.

CORDYCEPS OF JAPAN.
In Matsumura's list there is a
record of but one species of Cordyceps from Japan. There are four
species known, and no doubt a great many that are not known. I
trust my Japanese correspondents will pick up and dry every specimen
of a Cordyceps they note and forward to me. A few words in
regard to the collection of Cordyceps will not be amiss. Cordyceps
have only to be picked up and dried; but, as the host is usually
buried, care should be taken to dig out the host and forward it,
attached to the Cordyceps. They change very little in drying, so it
is not necessary to send them in alcohol. Simply lay them aside
for a few days and dry them, wrap in tissue paper, and place in a
little box and mail to my address. If you are an entomologist and
know the name of the host, it would add much to the interest if the
name of the host is stated on a piece of paper and enclosed with the
specimen.
