V. CORONATA (Hoffm.) Fr. 



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

 (Nuttall, 1263, 209). 

 V. ALBOPUNCTA E. & E., Field Mus. Bot., 1:133 (1896). 



TYPE HABITAT : On dead limbs Liriodendron Tulipifera, 

 Oct., 1894 (Nuttall, discov. 1712, 600). 



Stromato 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. 

 Perithecia 3 to 6 in a stroma, pale slate-color, no to 130 a 

 diameter; necks very slender, terminating in minute, subglo- 

 bose, slate-colored ostiola taridly erumpent around the mar- 

 gin of the minute, snow-white, pulverulent disk. Asci clavate 

 cylindrical, 50 x 6 /*, short-stipitate, obtuse above, paraphy- 

 sate? Spordia 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.
