Sphceria tumulata, Cke. Grev. VII, p. 4, 

 Amphisphceria tumutata, Sacc. Syll. 2751. 



Perithecia immersed, subglobose, black. Ostiola erumpent. Asci 

 cylindrical. Sporidia sublaneeolate, obtuse, nniseptate, dark brown, 

 35-40 x 12 //, with a hyaline apiculus at each end. 



On wood of Pinus contorta. Sierra Nevada Mts., California, alt. 

 8000 feet. 



A. thiijina, (Pk.)

Amphisphceria thujina, Sacc. Syll. 2750, Cke. Syn. 3446. 



Perithecia scattered, nearly free, hemispherical or conical, slightly 

 rugulose, thin and fragile. Ostiola at first slightly papilliform, then 

 perforated. Sporidia large, nniseptate, oblong-elliptical, constricted 

 at the septum, colored, 36-45 f long. 



On decaying wood of Thuja occidentalism Adirondack Mts., New 

 York. 



As no mention is made of any asci, this, as far as the description 

 goes, may be only a Diplodia. 



A. ithiops, (B. & C.) 



Sphceria cethiops, B. & C. Grev. IV, p. 143. 

 Amphisphceria cethiops, Sacc. Syll. 2731, Cke. Syn. 3436. 



Perithecia jet-black, subglobose, with a small, nipple-like ostiolum. 

 Asci clavate or oblong. Sporidia clavate-oblong, uniseptate, some- 

 times with a gelatinous coat, 33 /i long. 



On old logs, mountains of New York. 



Nothing is said of the color of the sporidia, but Cooke (1. c.) 

 places this in Amphisphceria, with species having brown, uniseptate 

 sporidia.

 Amphisphceria albomaculans, Cke. Syn. 3449. 



Perithecia scattered on a well-defined white spot, very black and 

 generally surrounded at the base by green, pulverulent matter, irregu- 

 larly hemispherical, of medium size, semiimmersed, punctate, acutely 

 papillate. Sporidia (sec. Cke. Grev. XVI, p. 91) uniseptate, brown, 

 12x3 fi. 



Schweinitz also observes that often the ostiola of 2-3 perithecia 

 are, as it were, connate, united into a single ostiolum, round or vari-
