SPORES HYALINE.
SECTION 95. CONTEXT BROWN. SETAE NONE.
POLYPORUS GOETHARTII.-Pileus dimidiate, concolorous
large specimens 15 x 9 x 2 cm. Surface brown, glabrous marked with
concentric, raised zones. Context dark brown (antique brown) hard
Pores minute, 4-6 mm. long, concolorous. Setae, none. Spores unknown,
doubtless white.
At Leiden only this species is found, having been recently named
from Java specimens. It is marked with raised zones, which are rare
in Polyporus and common in Fomes. What causes these in the plant
we do not know, but in Fomes these zones are formed by the annual
layers overgrowing and overlapping. As Polyporus Goethartii is only
known from one collection, this character may be unusual in this
specimen.

Polyporus melleofulvus.
POLYPORUS MELLEOFULVUS (Fig. 681). Pileus dimidiate,
pale brown (clay color). Surface subtomentose, soft, rough, concolous,
no distinct crust. Context dry, hard. Pores medium, 3 to mm.,
round or irregular, with thin walls. Spores (not found) teste Romell,
2-3 x 5-7, hyaline.
This is known only from type collections. There is a cotype at
Berlin. Romell put it in the "genus" Chaetoporus, which he abandoned
in recent papers, but the plant has no "chaete." There are
projecting hyphae which are sometimes encrusted, but nothing suggesting
setae.
POLYPORUS SUBSTUPPEUS. Pileus thin, applanate, with brown, rough
surface. Context thin, soft, 3 mm. (now) brown. Pores small, round, 2-3 mm.
long, dark brown (now), almost black. Setae, none. Spores globose, hyaline, 4 mic.
Known only from types at Kew from Brazil, which are none too good. The Australian
determinations are evidently different. We are not sure but that Polyporus sub-
