Stromata gregarious, scattered or subseriate and sometimes 

 confluent, erumpent-superficial, depressed-pulvinate, subhemispherical 

 or obtusely conical, 1-3 mm. diam., dull brick-red at first, at length 

 clay color or nearly black outside, brick-red or nearly blood-red inside, 

 oi subcarnose texture, more or less roughened and pitted from the 

 collapsing of the upper part of the perithecia which are arranged in a 

 single peripheric layer, 10-40 in a stroma, ovate, small (less than \ 

 mm. diam.), at length more or less emergent and collapsing above. 

 Asci clavate, sessile, paraphysate, 8-spored. Sporidia crowded-biseri- 

 ate, fusoid, 3-septate, slightly curved, light brown, end cells paler, 

 38-50 x 3J-5 a. 



On dead limbs of Carpinus Americana, Carolina, Pennsylvania. 

 New York (Brown), and Canada (Dearness). 



In some of the Canada specc. the stroma is reduced to a mere 

 crust on which stand the cup-shaped perithecia, exactly as in Fraechi- 

 cea callista. The red color of the stroma both inside and out finally 

 disappears.
