ed at the apex and at length perforated. Asci cylindric-clavate, 30- 

 40x5-6 it ip. Hp. 25-30 x 5-6 //). Sporidia biseriate, allantoid, 6-12 

 x l|-2 /JL. Spermogoma in similar stromata with a white disk and 

 large central pore, surrounded by smaller ones. Spermatia 5-7 x 

 1-1 1 //, erumpent in whitish cirrhi (when fresh), yellowish (when dry). 



On dead limbs of Juniperus Virginiana, New Jersey and 

 Delaware. 



Distinguished from V. Pini by its larger spermatia.

Stromata numerous, quite evenly scattered, depressed-conical, 

 sunk in the substance of the bark and raising the epidermis more or 

 less distinctly into pustules. Perithecia 6-10 in a stroma, subcircinate. 

 small, globose, buried in the unaltered bark, with very short necks. 

 Ostiola small, thickened, globose or ovate, acute or obtuse, black, with 

 a small, round pore; mostly crowded around the margin of a grayish- 

 brown disk, but sometimes occupying the entire disk. Asci narrow- 

 clavate, sessile, 40 x 6 p.. Sporidia crowded, cylindrical, hyaline, 

 slightly curved, 10-12 x 1 J-2 //. 



On dead limbs of Abies balsamea, Adirondack Mts, N. Y. (Peck), 

 Canada (Dearaess). 



Tliis species is peculiar on account of the spermogonia being pro- 

 duced on the leaves. They are very small, obtuse-conical, with their 

 apices projecting and crowned with a grayish-black disk bearing a 

 small, perforated papilla. The interior divisions are radiately arranged. 

 Spermatia cylindrical, hyaline, curved, 4-5 x 1 \ /JL. Distinguished from 

 the two preceding species by its longer sporidia.

Pustules covered by the slightly raised epidermis, which is pierced 

 by the pale, farinaceous disk. Perithecia few (3-6), buried in the un- 

 altered substance of the bark, Jmm. diam. or over, contracted 

 abruptly into slender, converging necks, with the conic-hemispherical, 

 slightly radiate-sulcate ostiola barely erumpent through the pale disk. 

 Asci clavate, 30-35x5-6 p. Sporidia biseriate, allantoid, slightly 

 curved, hyaline, 6-8 x 1| //. 



On dead limbs and trunks of Juniperus Virginiana, Carolina 

 and New Jersey.
