SPORES COLORED.
and is a true Polyporus. The bright yellow flesh is a marked character
of the species. It has been classed as Polystictus, and is the only
polypore with colored spores likely to be so classed on account of its
thinness. The plant has also been named Polyporus Splitgerberi and
Polyporus sulphuratus, neither a very suitable name for it.
SPECIMENS. Brazil, Anna Brockes, Rev. C. Torrend.
Compare hinnuleus, Splitgerberi, sulphuratus.
POLYPORUS CITREUS has been known since 1860 only from a little type at
Kew, from Australia, not much bigger than your thumb nail. It is thin, yellow, and
similar to Polyporus rheicolor, but the spores are very pale, with only the slightest
tinge of color.
SECTION 99. CONTEXT BROWN. SETAE NONE.
A. Plants very minute.
POLYPORUS PYGMAEUS. Pileus minute, erumpent from
branches, flabelliform. Color brown. Pores large in comparison to
size of plant. Spores, teste Murrill, 3>2 x 5, colored, abundant.
This is a unique little species, and disputes with Polyporus poculus
the honor of being the smallest Polyporus known. It is about 2 mm.,
only, in diameter. Palmer collected it in Mexico and sent it to Ellis,
who distributed it as Trametes pusilla. Patouillard evidently received
a specimen, for he lists it as "Xanthochrous pusillus, Ellis," Xanthochrous
being a new genus that he had "discovered" with yellow
spores. We therefore suppose its spores are colored, though the
material being scanty we did not examine them. But one collection
is known of this little species, which is at the New York Gardens.
It is not recorded whether it has setae or not. The name Polyporus
pusillus being preoccupied, my friend McGinty changes it to Polyporus
pygmaeus.
Compare pusillus.
B. Pores large. Similar to Hexagona and has been so classed.
