Stroraata ^i^attered, often standing close togetliei-. but not cou- 

 fiuent, orbicular or elliptical, varying from depressed-licinisplierical to 

 conical, covered by the epidermis or erumpent, brown oiit.^ide and 

 staining the adjacent bark the same color. Peritlii'ci;i o-'20 in a 

 stroma, crowded, globose, small. Ostiola more or less elongated, slen- 

 der, cylindrical, smooth, mostly united at base with their tips more or 

 less spreading. Asci narrow-clavate, sessile, 3'2-4()x4^.'i ii.. Sporidia 

 biseriate, allantoid, sh'aight or slightly curved, hyaline, (i-8 x 1^-2 //,. 

 On Betnla, QK.ercu.x, Garya, Atnelcmc/ner, Vlhumum, Crafai- 

 gus, Acer, Cornice:, and CMonanthus, common. ^ 



The ostiola in- all the American specc. we have seen, rcTilain 

 short, projecting but little above the epidermis. They^rtre often 

 clavate-thickened above. Prom a careful examination of J4ic specc. of 

 V. Qxcorians, in our Herli., we cannot separate this s'i'ieeies from V. 

 ceratophora, Tul. The sporidia (6-8 x lA «), and a.Jif tlie' other char- 

 acters of V. ejxnrlaiia. r/'^ree so well with the «'pecr. of V. cerato- 

 phora in the various Exs'iccati, that it cannot ^^ifely be scjjarated ns 

 specifically distinct. /

Pustules small (1^ mm.), flat, cover^-fl by the epidermis which is 

 pierced by the small fascicle of short-cylindrical, black ostiola, which 

 are rounded or subconical at the ap<3x. .Perithecia 3-8 in a stroma,
