“Stroma tuberculariform, pale yellowish within, becoming black 
outside, subpulvinate; perithecia densely coespitose on the stroma, 
globose-ovate, corrugate-rugose; ostiola obsolete, but showing as a 
dark-brown speck, about the size of S. cmmibarina, easily falling 
from the stroma. The perithecia at length become indurated, but 
do not collapse.” Specimens of Celastrus scandens, collected in New 
York State by VV. R. Gerard, agree well with the above-quoted char¬ 
acters, except in having the perithecia only one fifth or one sixth 
millim. in diam. and collapsed. We no not, however, consider this 
latter character in every case reliable, as it depends, in some measure, on 
the stage of growth at which the specimens are collected. In Gerard’s 
specimens, the stroma is not well shown, as it is already covered with 
and partially obliterated by the superimposed perithecia, which are of a 
bright red color at first, but at length dark red and collapsed, and have 
the surface subverrucose-roughened. The asci are cylindrical, 55—60 x 6 
or sometimes enlarged above to 8 or 10 a thick; sporidia 1-seriate, 
elliptical, 1-septate, not constricted, 7—8 x 3L—4 The groups of peri¬ 
thecia ,are about 1 millim. across. Notwithstanding the slight discrep¬ 
ancies, we are inclined to regard this as the species meant by Schweinitz, 
who found it rather rare on Celastrus, about Bethlehem, Pa. Peck, in 
2Gth Report, also mentions it as found by him at Greenbush, N. Y., but 
he gives no description of his specimens and we have not seen them.

CiBspitose, bursting out in groups of 3—10 through cracks in the 
bark ; perithecia subglobose, orange-red, smooth, at length collapsing,
