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 deutata, Nov. 14, 1893 {Nuttall, 

 1263, 2og). 



V. albopuncta E. & E., sp. nov. 



Type habitat: On dead limbs Liriodendron Tulipifera^ Oct., 

 1894 {Nuttall, discov. 171 2, 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 <j., 

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

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



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.
