Conidial stage consisting of a soft, fleshy, erumpent stroma 

 on the surface of which the conidia are produced ; conidiophores 

 slender, often several times the length of the spore, strongly 

 swollen just below the point of attachment; conidia broad- 

 ellipsoid, simple, 10-12 X 20-24 m- 



Apothecia thickly gregarious, springing in cespitose clusters 

 from an immersed, fleshy stromatic base, the individual apothecia 

 tuberculate, or expanded and subdiscoid, with a short, stem-like 

 base, often distorted by mutual pressure, reaching a diameter of 

 1-3 mm., pale-yellowish; hymenium plane, or convex, similar in 

 color to the outside of the apothecium; asci clavate, reaching a 

 length of 150-200 ju and a diameter of 15-20 n, 8-spored; spores 

 ellipsoid, straight, or slightly curved, granular within, for a long 

 time simple but often becoming 1-3-septate, 10-12 X 18-30 /x; 

 paraphyses slender, branched, enlarged above, reaching a diam- 

 eter of 5 ji, not forming an epithecium. 



On trunks and branches of Carpinus caroliniana. 



Type locality: Europe. 



Distribution: Massachusetts to Missouri and Pennsylvania;
