I find mingled with the fruit of this plant, long clavate, septate, 
slightly colored spores. Do both belong to one species ?

When moist the perithecia gap open at the apex, revealing the 
whitish gelatinous mass of spores within.

Perithecia small, scattered, black; spores excessively elongated, 
subfiliform, tapering to a long narrow point at each end, more or 
less curved, usually containing a row of nuclei, subhyaline .0025' to 
.003' long. 
Dead branclies of hemlock trees. Greenbush. April.

the epidermis by a transverse fissure, irregularly ruptured at the 
apex, black; spores hyaline, subfiliform, pointed at each end, con- 
taining a row of nuclei, .0013' to .0016' long.
