 Durandia Rehm, Ann. Myc. 11: 166. 1913. Not Durandia Bockel, 1896. 



Apothecia erumpent, coriaceous, black as in Tympanis; asci 

 clavate, containing many minute, spermatoid, spore-like bodies 

 as in Tympanis and in addition normal ascospores; paraph yses 

 filiform. 



Type species, Peziza Fraxini Schw. 



In a previous paper (Mycologia 37: 336) this genus was re- 

 garded as a synonym of Godronia. Groves (Mycologia 29: 79) 

 believes that this should be retained as a distinct genus. It 

 might be characterized as a Tympanis with ascospores. 



We have a similar situation in Scoleconectria of the Hypo- 

 creales in which the normal spores are often obscured by the 

 numerous spermatoid, spore-like bodies.

Apothecia erumpent in clusters of three to ten, or rarely 

 occurring singly, black, or blackish, reaching a diameter of 1 mm., 

 circular, or irregular from mutual pressure; hymenium plane or 

 nearly so, similar in color to the outside of the apothecium; asci 

 clavate, reaching a length of 120-150 m and a diameter of 10-12 m, 

 8-spored; spores filiform, attenuated at either end, septate, 2.5-3 

 X 50-90 M, accompanied by minute sprematoid, spore-like 

 bodies; paraphyses filiform. 



The apothecia often accompanied with Sphaerographium 

 Fraxini which appears to be its conidial stage. 



On branches of Fraxinus americana. 



Type locality: North Carolina. 



Distribution: North Carolina to Massachusetts, Ontario

12. MURANGIUM Seaver, gen. nov. 

 Apothecia as in Cenangium, gregarious, or congested; asci 

 broad-clavate, 8-spored; spores very large, ellipsoid, hyaline, or 

 brown, becoming muriform.
