fungi covered by the epidermis which is tinged with a dark ri^l coloj', 

 and swollen or inflated.

Perithecia immersed in the parenchyma of the leaf, covered bv 

 the epidermis which is bul late-inflated on both sides, gregarious, witli 

 a lateral, black, cylindrical beak. Asci exactly fusiform, 8-spored, 

 95-115x10-12//. Sporidia narrow-fusiform, straight, multinucleate, 

 2-septate, 48-52 x 4-5 /i. 



On fallen leaves of Salix glaucu, Sukkei'toppen and 8ermersut, 

 Greenland. 



Sporidia about three times as long as in H. pustula.

Perithecia sunk in the parenchyma of the leaf, covered by the 

 epidermis which is bullate-inflated on both sides, and is of a dark red- 

 dish tint below, scattered or gregarious, often following the coui-se oC 

 the nerves of the leaf, 200-hOO ^i diam.,. sometimes 2-3 confluent, 

 depressed-globose, with a short, lateral, tardily erumpent, beak-like 

 ostiolum. Asci clavate, attenuate-stipitate, thickened above, 70 x 8- 

 10 {I (75-100 X 7-10 (X, Sacc). Sporidia 8 in an ascus, biseriate, ob- 

 long-fusoid, rounded at the ends, straight or subinequilateral, becom- 

 ing 3-septate, but not constricted at the septa, 17-23x4 /i. 



On fallen oak leaves. Credited to America by Saccardo, in Syl- 

 loge. 



We have seen no American specimens. The figs. 12-15, on Plate 

 31, are from the specc. in Linhart's Fungi Hungarici. The synonymy 

 and diagnosis are taken from Winter's Pilze. The young sporidia 

 have (sec. Winter) a button-shaped appendage at the ends.

Stroma phyllogenous, black, radiose-asteromatoid, flattened. Peri- 

 thecia adnate with the stroma, separate, protuberant, with the ostiola 

 perforated. Asci 8-spored, obsoletely paraphysate, evanescent. Spo-
