nun. across. Perithelia in a single stroma, few or numerous, generally 

 crowded, rarely subconcentrically arranged, subsphaeroid or angular 

 from mutual pressure, small, necks converging. Ostiola short and 

 small or oftener more or less elongated, rough, sulcate-cleft, 3-6-sided r 

 connate, at least below. Asci cylindric-clavate, 40-50 x 5-6 ju (p. sp). 

 Sporidia crowded or subbiseriate, allantoid, yellowish, 7-11 (mostly 

 7-9) xl J-2 fi, (8-12 x 1 J 2 //, Sacc). Spermogonia many-celled, 

 larger than the ascigerous stromata. Spermatia filiform, curved.. 

 20-25 p. long, issuing in yellow cirrhi. 



Common oh limbs of various deciduous trees throughout* the 

 United States. 



Often when the pustules are crowded, a single circumscribing 

 line surrounds an entire group, and the surface of the 'inner bark is 

 uniformly blackened. As far as the specc. above quoted are con- 

 cerned, we can find no distinctive characters to separate Valsa ven- 

 triosa and V. tetraploa from this species, and have therefore included 

 them in Eu. stellulata, (see Cke. Valsei of the U. S. p. 112).

Perithecia 3-4, rather large, nestling in the inner bark and ren- 

 dering the surface bullate. Ostiola irregular, subpulverulent, black, 

 and (sec. Cke, Grev. XIV, p. 45), distinctly sulcate, and sporidia (see 

 Valsei U. S. p. 1 13) 12-14 p long. 



Rather rare on young shoots of grape vines, Carolina (Schw.), 

 Pennsylvania (Michener), New York (Peck). 



It is doubtful whether this is more than a var. of Eutypdla 

 stellulata, (Fr.).

Perithecia 6-12, subcircinately arranged and buried in the un- 

 altered inSer bark, about \ mm. diam., black, thick-walled, with con- 

 verging necks and stout, quadrisulcate, black ostiola erumpent in a 

 short, compact fascicle in the center of the pustule, closely embraced 

 by the perforated, slightly pustulate epidermis, above which they pro- 

 ject but slightly. Asci clavate, p. sp. about 35x5 /i. Sporidia 

 biseriate, allantoid, yellowish, 6-8 x 2 //, moderately curved.
