462 Duranp: Srupies IN NortH AMERICAN DISCOMYCETES 
stem 2-10 mm. long, slender, darker below, with the exterior of 
the cup delicately furfuraceous. Cortex very thin, of polygonal 
cells, 8-10 # in diameter, projecting in groups from the sides of 
the cup and upper part of the stem making the exterior furfur- 
aceous. Toward the base of the stem the cells are prolonged into 
short hairs, 4 in diameter. Hypothecium parenchymatous, 
cells rounded, 6-10 # in diameter. Medullary part of the stem 
and cup of slender hyphae loosely interwoven. Asci clavate, 
usually curved, about 75 x gy, apex rounded, not blue with 
iodine ; spores 8, biseriate, hyaline, smooth, continuous, eguttu- 
late, elliptical or ovate-elliptical, slightly unsymmetrical, 9-12 X 
4-5 #; paraphyses filiform. 
On the inside of decaying involucres of Castanea vesca, lying 
on the ground among leaves. Not uncommon in Coy Glen and 
Enfield Ravine, in the vicinity of Ithaca, N. Y., October, 1901. 
(Herb. Cornell, nos. 7942 and 7950, the latter the type.) 
This species resembles Ciboria (or Rutstroemia) echinophila 
(Bull.) Sace. in size, color, habit and habitat, but differs from it in 
the smaller spores (in the latter “ 12-22 4-5 1,” Phillips; “ 16- 
21x5 p,” Massee), which are not strongly curved, and which 
never, so far as observed, become septate. C. echinophila has 
been reported in America only by Schweinitz, from Bethlehem, | 
Pa., and his specimen may possibly have belonged to the present 
species. It may be that C. Americana will prove to be the Amet- 
ican representative of the European C. echinophila. 
Sclerotinia smilacinae sp. nov. 
Plants scattered on gregarious, long-stipitate ; sclerotia — 
1-2 mm. in diameter, irregularly spherical, aggregated and He 
times coalesced into a thin crust-like mass 1-2 cm. in diameter; 
ascoma fleshy-leathery, closed and spherical at first, expanding f° 
cup-shaped, finally becoming campanulate, usually with a e638 < 
sion in the center, sometimes contorted or irregular, .75-3 ca Y 
diameter, bright cinnamon-brown, externally smooth; stem 2 : 
cm. long, 2-3 mm. thick, tapering downward, somewhat pee 
tose below. Cortex parenchymatous, cells irregular, Lose 
diameter ; hypothecium and medullary portion composed of oo 
der hyphae loosely interwoven. Asci narrowly cy lindrical, 8P 
rounded, slightly blue with iodine, 120-140x 6-8 /; ees 
obliquely uniseriate, hyaline, continuous, biguttulate, smooth, re ; 
rowly elliptical, 12-15 x 4-5 4; paraphyses scarce, filiform, 
little thickened above.
