* WITHOUT CYSTIDIA. GROWING IN THE GROUND.
STEREUM ELEGANS (Fig. 539). Pileus glabrous, growing in
the ground, densely caespitose and confluent, imbricate, forming a
rosette, irregularly infundibuliform with thin maigin. Color dark,
reddish-bay. Stipes distinct. Hymenium often glaucous, uneven in
folds (hence incorrectly referred by some to Cladodenis). Cystidia,
none. Spores globose, hyaline, smooth, 4 mic.
This is a frequent plant, particularly in Australia. Its original
identity is based on Meyer's description, which has little application
to the plant usually so referred. It was one of the first foreign species
named. Meyer described it as above, "Gregarie crescens, subcom-
pressus, undulatoplicatus, ad terram argillosa," which has little application
to the usual determinations.
Its habits are peculiar, consisting of separate individuals, with
distinct stipes, the pilei becoming confluent into an imbricate rosettelike
cluster. It is very common in Australia, was originally from
South America, but evidently is widespread in the tropics. We have
specimens from India, Ceylon, and the West Indies. At Berlin Hennings
determined Stereum elegans as Stereum nitidulum. Berkeley
seems to have referred several different species to Stereum elegans.
ILLUSTRATIONS. None published. Figures cited, Patouillard and Hennings, both misdeterminations.

STEREUM FLORIFORME (Fig. 540). Caespitose, connate,
infundibulifoim or spathulate, glabrous excepting tomentose at base,
i eddish-bay color. Growing in the ground, caespitose, the individual
mostly concresive.
This is named on a sheet at Kew, a correction of Cooke's determination
of "Stereum Moselei" (with no resemblance to Moselei).
It is quite close to Stereum elegans, same color and habits of growth,
but is thicker, more spathulate, and the base of the stipe is tomentose.
I have a specimen (Fig. 540) from G. A. Gammie, India, which,
as far as the plant goes, seems to be same species, but the white
mycelium binds the soil together in a hard lump.
SPECIMENS. Dr. G. Zenker, Camerun, Africa (typical). G. A. Gammie, Poona, India.
STEREUM CRENATUM (Fig. 541). Pileus glabrous, deep,
reddish-bay color, subinfundibuliform, but more or less lobed and
irregular. Stipe slender, rooting, minutely tomentose.
This is rather a rare species, easily confused with Stereum elegans,
from which it differs in its separate habits of growth and slender
stipe. The type at Paris is a single head from Java. Recent South
American collections were distributed by Ule as Stereum petaloides,
as misdetermined by Hennings. At Paris is a specimen from French
Congo.
