brown; asci cylindric; sporidia oblong 10006’—.0008’ X .0003'—.0004’, 
ina single or double series, generally single below and crowded 
above. The fungus might easily be mistaken for a flattened, half 
dry globule of pitch.

Gregarious, sessile, small, about .o1’ in diameter, obconic or in- 
versely hemispheric, orbicular, flesh-colored when moist, pale orange 
when dry; margin smooth, obtuse ; asci slender, about .0o4’ long; 
paraphyses thickened at the tips ; sporidia uniseriate, placed end to 
end or lying obliquely, hyaline, narrowly-oblong, slightly curved, uni- 
septate .00035'-.0004’ x .ooo1’. The cups areslightly concave above, 
smooth throughout, and scattered thickly over the leaves of the moss 
on which the fungus grows—Substance carnose, rather tough—Rela- 
ted to P. mycogena, Ell., but larger and of a deeper color.

dead stems of Bidens. Nov.—March. 
Gregarious, stipitate, small, about $” broad and high, pale green- 
ish becoming darker; disk indistinctly margined, plane or plano- 
convex, becoming concave in drying; stem about half a line high; 
asci clavate-cylindric; sporidia biseriate, elliptic-fusiform, hyaline, 
binucleate, about .oo08’ long; paraphyses stout, thickened and 
colored olive green at their tips; stylospores about the same shape 
and size as the sporidia, faintly biseptate, with or without a hyaline 
apiculus, borne on threads or pedicels arising from the subhymenial 
layer with the asci and paraphyses and about $ as long. The stylos- 
pores are produced in the same manner as observed in Zympanis by 
Mr. Berkeley and figured by him in his Zntroduction to Cryptogamic 
Botany. p. 244.

sporidiis biseriatis, cylindraceis, curvatis, hyalinis. —On decaying 
Oak, lying on the ground. January. 
Perithecia small, black, thickly scattered over a loosely compacted, 
fibrous, light yellow subiculum ; ostiola not prominent, with a rather 
large opening ; asci clavate, with a long slender stem about 
.004' X 0003’; paraphyses linear, with a row of nuclei, not thickened 
above ; sporidia, as in some species of Valsa, biseriate or crowded 
above, cylindric, hyaline, curved, .oo05’ long. 
The yellow subiculum is more noticeable when sterile, extending 
for an inch or more in length and breadth and penetrating, and
