30 PROCEEDINGS OF THE ACADEMY OF [1895. 



"Perithecia loosely gregarious, cespitose or subconfluent, subglobose 

 at first, then erumpent-superficial, depressed- cylindrical, or almost 

 thick-discoid, with a large, irregular opening; almost rimose-dehis- 

 cent, black, about 150,u high and 250// broad. Sporules cylindrical, 

 straight, hyaline, 7-10 x 2-2ifi, borne terminally or laterally on 

 filiform basidia of various length." 



From the above diagnosis it is plain that the Sphceria palina in 

 Herb. Schw. is quite distinct from Sphceria palina Fr. 



Sphceria Gossypii Schw., Syii. Car. . 207. 



This is an obscure thing. The inner membrane of the cotton 

 boll is wrinkled or roughened in drying so as to give the appearance 

 of minute perithecia, but there is no fruit or even any real perithecia. 



Sphceria fraxicola Schw., Syii. N. Am., 1,787. 



The spec, has the aspect of Sphcerella maculiformis, but is entirely 

 sterile. . 



Sphceria vilis Fr., in Herb. Schw., is Ohleria modesta, Fekl., and 

 quite different from Sphceria vilis, Fr. , in Fr. S. M., II, p. 466. See 

 Ell. & Evrht, N. A. Pyr., p. 217. 



Sphceria stricta Pers., Syn., p. 59. 



There are two specc. ; one with scattered, buried perithecia (Cera- 

 tostoma cirrhosa (Pers. ), the other with clustered, superficial peri- 

 thecia. The latter may 'be Ceratostomella stricta, but the perithecia 

 are empty and broken, only the lower part remaining. 



Sphceria mamillana Fr. in Herb. Schw. 



The spec, so labeled is the same as Myxosporium nitidum B. & C. 



Sphceria Tilice Schw. , in Herb. Schw. and Sphceria distineta Schw. , 

 Syn. North Am., 1,655, are (sec. specc. in Herb. Schw.) only the 

 sterile pycnidia of Melanconis Tilice Tul. , or of M. tiliacea (Ell.). 



Sphceria Polygonati Schw., Syn. N. Am., 1,793, is a young and 

 undeterminable Vermicularia. 



Sphceria Andromedce Schw., Syu. X. Am., 1,796. 



Perithecia subcuticular, minute, thickly scattered over the lower 

 side of the leaf, not in spots. 



Old and without fruit of any sort.
