Perithecia ccspitose, jrloliose, abont J mm. diam., verrucose- 

 roughened, light ])rick-red, heconung nuich darker and finally collaps- 

 ing above, more or less distinctly clothed with weak, short, rudi- 

 mentary, hyaline, glandular hairs, seated on an orange-red, concave or 

 depressed stroma {Tiiberculariu), forming groups 1-2 mm. diam., at 

 length more or less deciduous. Asci oblong-cylindrical, with a short, 

 substipitate base, 60-70 x 10-12 /i. Sporidia Inseriate, oblong, uni- 

 septate, 12-18x4-5 /t. The stroma, as in most other Nectrim, is 

 finally hidden and partially obliterated by the perithecia. 



Common on Moms and Sassafras, Pennsylvania (Hchweinitz), 

 on Morns, Melia, etc., South Carolina (Ravenol), and on Morns, New 

 Jersey (Ellis). 



Differs from N. viimaharlna in its concave, scarcely [)rominent 

 stroma, the peculiar roughening of the perithecia, and in its shorter 

 asci, and mostly narrower s|)oridia. N. coccruca has the perithecia 

 nearly smooth, or when tlry, slightly furfui-aceous.
