Peritlieeia scattered, covered, toleralily large, lenticular, black, 

 with a round, slender l>eak l-l^ lines long arising from the concave 

 f<ide of the ))erithecium. Asci elliptical, stipitate, 8-spored. Sporidia 

 fusoid, often curved, continuous, binucleate, hyaline. 



On petioles of decaying leaves of Aver riihrtoii, Newfield. N. .'. 



In the Newfield spccc. the a,«ci are oblong-ellijitical. 70-80 x 15- 

 20 /i. Sporidia fasciculate, liroad-fus<jid, 4-nucleate, 25-30 x4J //, 

 with a broad (6-8x4 /i). ovate, hyaline ajtpendage at each end, I ait 

 this is soon absorbed. See Journ. Glycol. IV, p. 81. 



Whether this is really the G. eniarghmfa. Fckl., may 1>c open to 

 some doubt. The speec. distributed in Fungi Khenani are (sec. Win- 

 ter) immature, affording neitlier a.'^ci nor sporidia and no measui-enients 

 are given in the original diagnosis. In the Newfield speec, as well a? 

 in those in the Exsiccati quoted, the jterithecia can hardly 1k3 called 

 •'emarginate," though some of them are slightly so. Peck's jSp/uci'ia 

 mii'dhilis (on fallen bii'ch leaves) certainly belongs here.
