SECTION LIGNOSUS.
color. I am told that it is caused by a Hypomyces, but I am unable to detect
the mycelial threads of a parasite in the tissue and it does not seem to explain
it to me. The spores which I think are conidial are subglobose, hyaline, apiculate,
and distinctly rough. I have a specimen from L. Damazio, Brazil, and there
is one at Kew from Georgetown, British Guiana.
PAUL/EN SIS. Known by a single specimen from Brazil at Berlin. If not
the same it is quite close to pansus. It has a well developed, ligneous, white
context and hyaline globose, 6-7, smooth spores. Otherwise it seems the same
as pansus, particularly in its peculiar, zoned surface.
HYPOPLASTUS. Surface dark, almost black, faintly zonate.
Stipe black, smooth, with a resinous crust. Context pale isabelline.
Spores not found, but I think they are white. The type is a mesopodal
plant, but Berkeley refers 'here (and I think correctly) two flabelliform
specimens. All are from northern South America. This plant
differs from all others in this section in its laccate stem. While I
have found no spores, I believe it does not belong to the section
Ganodermus.
CAMERARIUS. Pileus reniform, smooth, even, glabrous, beau-
tifully zoned with narrow, regular, concentric, brown zones. Stipe is
pleuropodal (in one specimen, probably the same, it is mesopodal)
with a dull crust. Context pale isabelline, probably white when fresh,
2-3 mm. deep, almost reaching the crust. Spores not found, probably
white. Several specimens of this are at Kew, all from northern South
America.
ARENATUS. Pileus flabelliform, subligneous, incurved in dry-
ing. Surface gray, strongly zoned. Context white. Stipe lateral,
short, thick. Pores minute, rigid, pale. A strongly marked species
from New Guinea found in the Museum at Paris.
RHIZOMATOPHORUS. Pileus flabelliform, thin, with smooth,
pale isabelline surface. Pores minute, concolorous. Stipe slender,
long, attached to a slender, long rhizome. A single specimen of this
is at Berlin, from Brazil. It is endorsed "=Trametes Rhizophorae"
which is surely an error.
PUDENS. Known from a single, young, half specimen at Kew, from India.
It has a long rhizome and in some respects it resembles the preceding. I think
not much can be ascertained from this single, immature type, but it may be
recognized through comparison if found again.
POLYDACTYLUS. This is known from one apparently abnormal specimen
from Brazil. It has white context and a lateral stipe which divides and
bears on the ends of the branches little, orbicular, disc-like pilei. The surface
is minutely velutinate, brown, and marked with metallic zones. In its general
nature I think it is related to corrugis of Europe.
ATRO-PURPUREUS. This is also known from a single specimen from
Brazil, and has the same context color and surface marking as the preceding.
The pilei are thinner and borne in a different manner. The pore mouths are
white, but when bruised are reddish. I think the plant is badly named.
