SECTION 3.
Stipitate, with a mesopodial 01 lateral stipe. Smooth, bright color when fresh,
yellow in one species, bright purplish-red in another.
STEREUM AURANTIACUM (Fig. 538). Pileus mesopodial
infundibuliform, or spathulate with lateral stipe, both shapes found
sometimes in same collection (as shown on Montagne's figuies), but
usually the collections are either all mesopodial or all pleuropodial.
Smooth, minutely silky, striate, the base of the stem with a yellowish
tomentum often forming a little disc on the host. Color of dried
plant fresh, uniform, yellow, but my collection notes in Samoa give
the hymenium surface as bright sulphur yellow, upper surface pale
yellowish white. Stipe pale, almost white. Old specimens lose the
bright color of fresh plant and become brown.

Stereum aurantiacum.
I think there is but one yellow, stipitate Stereum in the tropics,
although spathulate and infundibuliform collections appear quite different.
Montagne and Spegazzini both claim they are the same
species, and a collection we have from Madame Anna Brockes, mostly
infundibuliform, a few spathulate, bears out this view. Persoon
described it as petaloid. We think the position of growth has much
to do with the form.
The types of Stereum aurantiacum both at Paris and Leiden
are not surely this plant, but more probably Stereum affine. They are
old and discolored, but Persoon's color description does not refer to
affine, hence I have taken the name in the sense of Montagne's and
Berkeley's more recent specimens, and apparently from the description
in the original sense.
ILLUSTRATIONS. t Beautifully illustrated by Montagne, Voyage La Sagra, Plate 1 (not Persoon
s Voyage Freycinet, as incorrectly cited in Saccardo's citation of Icones).
SPECIMENS. Anna Brockes, Crixas, Brazil, mostly mesopodial; C. G. Lloyd, Samoa, all pleuropodial.
It was quite rare in Samoa.
STEREUM HARMANDL Pileus spathulate, flabelliform, thin,
glabrous, peculiar puiplish-ied color. Stipe short, evidently growing
in the ground.
