BURT—THELEPHORACEJE OF NORTH AMERICA. I 215 
ate and somewhat imbricated, fibrous-tomentose, margin thick 
and entire; substance concolorous with the upper surface, 
spongy, more than 2 mm. thick, with hyphae 4%-би in diam- 
eter; hymenium inferior, even, not polished, cinnamon-buff ; 
basidia simple; spores deep olive-buff under the microscope, 
echinulate, 8-10 x 6-8y. 
Pileus 2-4 em. in diameter when circular, or 1-23 cm. long, 
2-4 em. broad, often 1 cm. thick at base when dimidiate. 
Running up and encircling twigs on the ground and against 
the base of shrubs. Canada to Louisiana and west to Wiscon- 
sin. August. 
Peck describes the odor as quite fragrant at first but states 
that it is lost after а few weeks; I did not notice any especial 
odor for my collection. Т. albido-brunnea may be distinguished 
from our other dimidiate and reflexed species of Thelephora by 
its even and pale hymenium and thick spongy pileus. Schwei- 
nitz confused one collection of this species with T. biennis Fr., 
from the specimen of which in the Fries Herbarium, at Upsala, 
itis clearly distinct. Тһе types of Stereum spongiosum Massee, 
viz., Curtis, 3582, and Ravenel, 1732, in Kew Herbarium, have 
colored echinulate spores 8-10 x 6-74, although described by 
Massee as “еШірвоідеге 6-7 x 4u” without mention of color and 
projections of the wall. The type of T'helephora odorifera Peck, 
in Coll. N. Y. State, is somewhat bleached or faded but quite 
typical.
