Perithecia cespitose-erumpent, or, when on decorticated wood, 

 superficial, spherical, collapsing to cup-shaped, bald and black ; texture

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

 closely surrounded by the ruptured epidermis, spherical, but collapsing 

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

 into a stipe-like base, and surrounded by filiform paraphyses, 8-spored. 

 Sporidia subbiseriate, allantoid, slightly curved, hyaline, with a nucleus 

 in each end, 9-10 J x 2-3 ju. 



On dead branches of various deciduous trees, Tilia, Acer, Pni 

 7ius, &c, on bark of Negundo Aceroides, Montana (Anderson, 276). 



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.
