 2 : 535. 1822 



Corynelia Acharius, in Fries Obs. Mycol. 2 : 343. 1818. 

 Type species, Corynelia uberata Fries ex Acharius. 



Stromata black, formed within the host tissue, later erumpent, 

 usually small and scattered, in C. fructicola confluent to form an 

 effuse crust, bearing pdrithecia and in some species also pycnidia , 

 perithecia seated on the stroma, cespitose, elongated (flask- 

 shaped, barrel-shaped, top-shaped, clavate, etc.) the apex rounded 

 and undifferentiated, or definitely lobed, in C. fructicola flattened 

 into a disc as in Tripospora; not provided with a typical ostiolum, 

 at maturity dehiscent either by a wide opening resulting from one 

 or more deep clefts, or as in C. fructicola, fimbriate-lacerate at 

 the apex and. finally dehiscent by a wide funnel-shaped opening; 

 asci ovate to clavate, long-stalked, thin-walled, evanescent, usually 

 8-spored (varying from 1-8), aparaphysate ; ascospores when 

 young hyaline, smooth and by mutual pressure polyhedral ; at 

 maturity, spherical, brown, thick- walled, echinulate, unicellular; 

 pycnidia seated on the stroma among the perithecia, more or less 

 globose, black; pycnospores hyaline, elongated to fusiform, uni- 

 cellular. 



In this genus the ascospore is provided with a thin, echinulate 

 epispore and a thick endospore. On young spores the echinula- 

 tions are slightly developed or absent. The endospore at ma- 

 turity is provided with a considerable number of definite circular 

 thin-spots or perforations which are probably germ-pores. These
