 Kxsicc. Fckl. F. Rh. 915. 



Perithecia gregarious, partly sunk in the matrix, globose, with a 

 flat base, 400-450 fi diam., with an obtusely conical ostiolum erum- 

 pent through the black, epidermal shield, and surrounded with a 

 whitish zone. Asci narrow-cylindrical, short-stipitate, 8-spored, 150- 

 160x8-9 /i. Sporidia uniseriate, oblong-lanceolate, subattenuated 

 and rounded at the ends, subinequilateral, 3-septate, brown 19-24x 

 5-6 fi. 



On branches of Celastrus, Bethlehem. Pa., (Schw.). Diagnosis 

 from Winter's Pilze. 



CI. imperfecta, E. & E. (in Herb.) 



Perithecia gregarious, globose, | mm. diam., covered by the epi- 

 dermis which is raised into strong pustules blackened and pierced 

 by the erumpent, papilliform ostiolum. Asci broad clavate-cylindrical. 

 80-100 x 20 fi. Sporidia biseriate, elliptical, 3-septate, brown, 20-30 

 x 10-12 /i, subinequilateral, slightly constricted at the septa. 



On bark of living birch, Syracuse, N. Y. (Underwood). 



This has the aspect of a lichen (Pyrenula) but seems really more 

 closely allied to Clypeosphceria mamillana (Fr.).

 Clypeosphczria f aliquanta, Sacc. Syll. 3198. 

 Heptameria aliquanta, Cke. Syti. 49S4. 



Perithecia scattered, covered by the blackened epidermis, 200 u 

 diam., or less. Asci oblong-clavate, p. sp. 65-70 x 12-15 , paraphy- 

 satc. Sporidia crowded-biseriate, oblong-fusoid, slightly curved, hya- 

 line and uniseptate, becoming yellowish-hyaline, 3-septate and slightly 

 ronstricted at the septa, 20-25 x8-10 ju including the broad, hyaline 

 envelope, the body of the sporidium being mostly only 18-20 x 6-7 ft. 



On dead stems of Smilax, Newfield, N. J. 



Cooke makes the sporidia 30-35 x 10 /a, but we do not find them 

 as huge as that, nor do they ever appear to become brown, only yel- 

 lowish-hyaline.
