170 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
Canada, throughout the United States, except in the Rocky 
Mountain region, in Mexico and the West Indies. July to 
January. Common in the United States. 
S. rameale varies somewhat under the different conditions as 
to climate and substratum in the great extent of North America 
where it is our commonest species of Stereum. In the United 
States and Canada one will hardly go amiss in referring to 5. 
rameale any Stereum with numerous small pilei densely crowded 
together imbricately or laterally, strigose hairy near the region 
of attachment, and with marginal side shining, somewhat zonate, 
and pinkish buff to hazel in color, and with these pilei drying 
folded together along the sides, or radially plicate in a laterally 
confluent form. The pileus of S. rameale is thinner than that 
of S. hirsutum, only partially covered with hairs, which do not 
form as heavy a covering where present, and the pilei are folded 
together laterally and are smaller than those of S. hirsutum. 5S. 
sericeum has small, shining, very thin pilei between whitish and 
pale drab-gray on both surfaces—wholly lacking ruddy ochra- 
ceous coloration—and almost always growing on Carpinus 
caroliniana. 
Schweinitz communicated to Fries specimens of S. rameale 
which are still preserved in the herbarium at Upsala; Fries 
published the species as a synonym of S. hirsutum in Elenchus 
Fung.; Schweinitz yielded to the authority of Fries but pro- 
tested that S. rameale was a distinct variety, at least. Other 
American specimens of this species were received by Fries, who 
described and published them in 1838 as S. complicatum, over- 
looking the earlier and nearly identical specimens from Schwei- 
nitz and the earlier, appropriate name for the species.
