418 PROCEEDINGS OF THE ACADEMY OF [1895. 



short-stipitate, 65-75 x 6-7 //, with faint paraphyses. Sporidia 

 uui seriate, navicular, 2-nucleate, 12—15x5-6//, hyaline at first, 

 becoming opake and nearly black. 



One would expect this to be Sphaeria investita Schw. , Syn. N. 

 Am. 1,621, but the specc. of that species in Herb. Schw. are not 

 distinguishable from Ceratostomella eirrhosa (Pers.) except in having 

 a small patch of yellowish-brown tomeutum around the base 

 of the ostiola. 



Ceratostoma albomaculans E. & E. 



On rotten wood. Ohio. Morgan. 



Perithecia entirely buried, large (1 mm. diam.), membranaceo- 

 coriaceous, 1-3 together. Ostiola erumpent, ovate-conical, black, 

 smooth. Asci cylindrical, p. sp. 75-80 x 7 //., paraphysate. Sporidia 

 uniseriate, inequilaterally elliptical, obtuse 1-2-nucleate, olive- 

 brown, 11-14 x 5-6 ,". 



The ostiola are erumpent in a yellowish-white subelliptical spot 

 1-2 mm. in diameter. 



C. avocetta C. & E. has the perithecia only half as large and 

 the sporidia smaller; the white spots also, under which the perithecia 

 are buried, seem to be characteristic. 



Amphisphaeria confertissima E. & E. 



On weatherbeateu wood, Ohio. Morgan. 



Perithecia superficial, subglobose, 210-220// diam. slightly 

 papillate-roughened, black, densely crowded in oblong patches 

 \— 1 cm. long and 2-3 mm. wide or often by confluence of greater 

 extent. Ostiolum papilliform, black. Asci cylindrical, short-stipitate, 

 p. sp. 55-60x8//, paraphysate, 8-spored. Sporidia obliquely 

 uniseriate, ovate-elliptical, brown, uniseptate and constricted, 

 9-11x5-6//.. 



Comes near A. Spegazziniana Sacc. but that has larger, short- 

 fusoid, sporidia and (sec. fig. in F. Ital. 135), slightly swollen each 

 side of the septum. 



Amphisphaeria pilosella E. & E. 



On decaying wood of some deciduous tree. Ohio. Morgan, No. 

 1,103. 



Perithecia gregarious, superficial, subcarbonaceous, minute, 200- 

 250 ,". diam., subglobose, slightly collapsing above, sparingly clothed 

 at first with short, pale, weak, spreading hairs. Ostiolum papilli-
