SporIDESMIUM concINNUM Berk. 
: Decaying wood. Markham Station. Clinton. May. 
CLASTERISPORIUM UNncINATUM Clinton n. sp. 
Thinly effused, blackish-brown ; spores large, subfusiform, straight 
or curved, five to seven-septate, colored, .0016'-.002' long, tapering 
below into the pale or colorless septate short pedicel which is strongly 
curved, coiled or uncinate at the narrowed base. 
Lower surface of fallen oak leaves. Buffalo. Clinton. Nov. 
The cells of the spores are often nucleate, and the terminal cell is 
sometimes truncate and paler than the others. The uncinate base of 
the pedicel is a characteristic feature. (Plate 1, figs. 9 and 10.) 
C. pedunculatum, which in a former report was referred to this 
genus, must be placed in the genus Helminthosporium. It becomes

PHRAGMIDIUM GRACILE (rev. 
Leaves of Rubus odoratus. Bethlehem, Trenton Falls and Watkin’s 
Glen. September. 
This plant was formerly reported as a variety of Phragmidiwm 
mucronatum, but having compared it with authenticated European 
specimens of both forms of that species, I am satisfied that our plant 
is distinct. In the Uredo form the spots are more definite, the sori 
and spores are larger and the latter have a more coarsely-roughened 
epispore. In the Brand form the spores are longer and yet more 
narrow, the papille are more prominent and the mucro is generally 
longer and roughened.

Puccrnta Puysostecia P. & C. n. sp. 
Spots none; sori evenly scattered, small, rotund, surrounded by 
the ruptured epidermis, blackish-brown ; spores elliptical, scarcely 
constricted, .0014’-.0016' long, .0008’-.001' broad; pedicels short,
