This species is close to Calycina firma but seems to differ in 

 that it is less robust and lighter colored, yellowish instead of 

 brownish. The only American specimen seen is one collected by 

 H. H. Whetzel, No. 10784.

Apothecia solitary, scattered, becoming patellate, stipitate, 

 reaching a diameter of 4 mm., externally showing faint longi- 

 tudinal striations, pale-brown, the margin dentate; stem slender, 

 usually tapering gradually below, becoming reddish-brown, 

 nearly black at the base; hymenium slightly concave, ochraceous 

 to cinnamon-brown; asci clavate, reaching a length of 95-120 n 

 and a diameter of 9-12 /x, 8-spored; spores 1-seriate, or 2-seriate 

 above, oblong-reniform, 4.5-5.5 X 14-17 n, at first 1-septate, 

 later 2-3-septate, producing spermatia from the tips of the 

 ascospores; paraphyses simple, enlarged above, 2.5-3.8 jj. at 

 their apices. 



On rudimentary stromatic base on the petioles and midribs 

 of overwintering leaves usually of Fagus and Quercus. 



Type locality: Europe. 



Distribution: Iowa to Maine and North Carolina; also in 

 Europe.

As will be seen, from the synonymy, this species has been 

 placed in several genera at different times and by different 

 authors. Saccardo placed it in Cyathicula because of the 

 slightly dentate margin. It seems to the writer to belong to the 

 present genus, largely on the basis of its spore characters.
