BURT—THELEPHORACEAE OF NORTH AMERICA. VII 325 
The above description is based on the Schweinitzian type 
and presents the characters of a rare species which has not 
been distinguished heretofore from the following S. pseudo- 
pedicellatum, a thicker, larger, common, and widely distri- 
buted species. S. Schweinitzii is characterized by its erect 
filiform paraphyses, curved to hook-shaped, spore-bearing 
organs, and small spores, although it is not certain that full- 
sized mature spores have yet been seen. 
I refer to S. Schweinitzii a collection made by P. L. Ricker 
on Persea, in Georgia, during August, because this specimen 
has small probasidia, hook-shaped, few-celled, hyaline, spore- 
bearing organs, and spores 7 X Alan: but in this specimen 
only a few paraphyses are present, the probasidia and hook- 
shaped organs are at the very surface of the hymenium, and 
small, globose organs би in diameter are occasionally pres- 
ent, borne laterally on the hyphae in the lower part of the 
hymenial layer. I have not studied with the microscope the 
Cuban specimen of S. pedicellatum, collected by C. Wright, 
one of the species upon the structure of which Patouillard 
founded the genus Septobasidium. He found this specimen 
to have probasidia and hook-shaped organs. Both proba- 
sidia and the hyaline organs are described as larger than 
they measure in the Sehweinitzian type. In the Cuban speci- 
men the probasidia are stated to be 20& in diameter or 20 
x 15и, and the hook-shaped organs as 35 X 10и, and the 
former persist full size, with the septate hook-shaped organs 
connected with them like a promycelium with its teleutospore. 
These differences indicate that the Cuban specimen belongs 
to a species distinct from Thelephora pedicellata Schw. It is 
necessary to substitute a new specific name for '*pedicellata"' 
in making the transfer of Thelephora pedicellata Schw. to 
Septobasidium, because there is already a valid Septobasi- 
dium pedicellatum. 
Specimens examined: 
North Carolina: Schweinitz, type (in Herb. Schw.).
