reaches a very large size. There is a specimen at Leiden from Java nearly eight feet
in circumference and weighing over 20 pounds.
The large, thick, deeply colored setae-like hyphae that are imbedded in the
tissue (Fig. 600) are the most remarkable feature of this plant, but were only referred
to vaguely as "cystides volumineuses" in the original accounts, and it is only
recently that special attention was drawn to them. I think they are mistermed as

cystidia in any possible meaning of this elastic word. It is of quite peculiar "structure,"
but other Fomes species, lamaensis, Polyporus Chaperi, glomeratus, Rickii,
and others have similar structure. Some day some bright savant will discover that
this structure forms a "new genus." Prof. McGinty proposes for it the name
Oxyuris.

FOMES MELAXODERMUS. Pileus ungulate, with a rough,
hard, black crust. Context dark, brown (antique brown). Hyphae
of two types, thick seta-like, darker hyphae imbedded in the lighter
colored, thinner hyphae of the usual type. Pores minute, concolorous,
in many distinct layers, 3-4 mic. thick. Setae rather thick, with
thick bases. Spores abundant, globose, pale colored, 4 mic.
It appears to be rare, and is only known from Java. The only
specimens I have seen are the one at Kew and the type in Patouillard's
herbarium. It is very close to Fomes lamaensis and has same
"structure," but differs in its abundant, colored spores.
FOMES LINTEUS. Pileus applanate, thin (5 mm. thick),
with brown, slightly tomentose surface, strongly sulcate, with con-
