JAN. 1896. FLORA OF W. VIRGINIA MILLSPAUGH & NUTTALL. 133 



mis is raised into subdiscoid pustules in which the slight protub- 

 erances indicate the position of the subjacent perithecia. 



V, delicatula C. & E. has fewer, larger perithecia and broader 

 sporidia. V. miscrospora Cke. & Plowr. has also larger perithecia 

 and yellowish sporidia, and the ostiola are more or less distinctly 

 sulcate, indicating its close relationship to Eutypella. In V. eth- 

 erialis the sporidia both in and out of the asci are perfectly 

 hyaline. 



V. coronata (Hoffm.) Fr. 



On young, fire-killed Castanea dentata, Nov. 14, 1893 (Nuttall, 

 1263, 209). 



V. albopunctaE. & E., sp. nov. 



TYPE HABITAT: On dead limbs Liriodendron Tulipifera, Oct., 

 1894 (Nuttall, discov. 1712, 600). 



Stromata minute (.5 to 7.5 mm.), subseriate, included in the 

 thick epidermis and not penetrating the inner bark, white 

 throughout, and without any distinct circumscribing line. Peri- 

 thecia 3 to 6 in a stroma, pale slate-color, no to 130 // diameter; 

 necks very slender, terminating in minute, subglobose, slate- 

 colored ostiola tardily erumpent around the margin of the minute, 

 snow-white, pulverulent disk. Asci clavate-cylindrical, 50 x 6 /.*, 

 short-stipitate, obtuse above, paraphysate? Sporidia biseriate, 

 allantoid, hyaline, moderately curved, 6 to 9 x 1.5 to 2 /z. 



A beautiful species. The lines of snow-white disks, which 

 barely perforate the ruptured epidermis and are closely sur- 

 rounded by its torn and slightly raised margin, present a very 

 neat appearance.
