 Exsicc. Fckl. F. Rh. 607. Sacc. M. Ven. 186. 



Pustules subcuticular, scattered, small, slightly prominent. Peri- 

 thecia 3-6, about \ mm. diam., with short necks terminating in the 

 short-cylindrical ostiola, conical at the apex, smooth or slightly sulcatc, 

 and erumpent in a compact tuft in the center of the pustule, hut not 

 much exserted. Asci clavate, p. sp. about 40 x 6-7 fi. Sporidia 

 biseriate, allantoid, only slightly curved, hyaline, 8-10 x 1^-2 //. 



On small, dead shoots of grape vines, Newfield, N. J. Sent also 

 from Louisiana (Langlois, 1767). 



The sporidia in the Louisiana specc. average larger (8-12 /i long), 



but there is no other difference. The perithecia lie in the unchanged 

 substance of the bark without any circumscribing line, and in well 

 developed specc. each separate perithecium raises the bark above it 

 slightly, as in V. ambiens. 



On the Newfield specc. are also spermogonia, multilocular, gray 

 inside, opening by a common central pore, and a little more prominent 

 than the ascigerous pustules. Spermatia allantoid, hyaline, 4x1 fju 



This is evidently the V. vitigera, Cke., and is quite distinct from 

 Eutypella Vitis, (Schw.), which has stouter, sulcate ostiola and 

 smaller, yellowish sporidia, and is in fact only a form of En. stdlulata. 



V. ligiistrina, Cke. Grev. VIII, p. 14. 



Stromata cortical, brown within, but not circumscribed, small. 

 elliptical, about l\ xl mm., raising the surface of the inner bark into 

 slight pustules which are not noticed till the outer layer is stripped 

 off. Perithecia 3-8 in a pustule, ovate, small. Ostiola erumpent 

 through longitudinal cracks in the outer bark, but not exserted, stout, 

 cylindrical, with the apex at first conical, then broadly and irregularly 

 perforated. Asci elavate-fusoid, about 35 x 6 /*, 8-spored. Sporidia 

 biseriate, allantoid, hyaline, moderately curved, 7-9 x 1J-2 (i. 



On bark of dead Andromeda ligustrina, Newfield, N. J. 



The ostiola are smaller and the sporidia rather larger than in 

 V. delicattda, and the fascicles of ostiola are laterally compressed. 



V. Liquidambaris, (Schw.) 



Sphceria Liquidambaris, Schw. Syn. N. Am. 1352. 



Valsa Liquidambaris, Cke. Valsei U. S. No. 29, Sacc. Syll. 477. 



Pustulate, small. Perithecia decumbent, 10-20 in a pustule. 

 Ostiola minute, crowded, conical-globose, rounded at the apex and 

 smooth, or sometimes faintly sulcate-striate, erumpent in a close fascicle,
