Type locality: Louisiana. 



Distribution : Known only from type locality.

Distinguished by the large coarsely furfuraceous perithecia. 



This species has been reported but once and the type speci- 

 men seems to be quite distinct in the presence of the bran-like 

 granules with which the perithecia are covered but whether this 

 character is constant must be decided from a study of fresh 

 material.

 mic, i-septate, hyaline; in addition to the ordinary ascospores 

 there are other large, hyaline, i-septate, spore-like bodies 30-45 

 X 18-25 mic. present in the perithecia {pl. 5. /. 2).
