Perithecia cespitose, emmpent in small (2 mm.), dense clusters 

 closely surrounded by the ruptured epidermis, spherical, but collapsing 

 to cup-shaped, 200-300 p. diam. Asci 40-60 x 7-8 ^, contracted below

The Montana specimens are the only American specimens we 

 have seen. They agree in all respects with the specc. in Thum. M. U. 

 and with the description of this species in Winter's Pilze and Sac- 

 cardo's Sylloge.
