188 NEW AND RARE BRITISH FUNGI. 



10. Sphasria carbonaria. n. s. 



Crowded, globose, semi-immersed, having an obtuse rugulose 

 ostiolum, clothed at the base with branched septate hyaline threads ; 

 asci cylindrical, commonly truncate at the apex ; sporidia almond- 

 shape, dark-brown, with a very short hyaline tail, uniseriate ; para- 

 physes linear. Sporid. -0009 X -0003. 



On burnt ground, near Shrewsbury, 1873. 



This appears to be allied to S. rotula, Cooke.

11. Sphaerella Iridis. Gon. Sf Rabh. Myc. Eur. t. o.f. 71. 



Amphiginous, black, at first covered by the epidermis, then some- 

 what free, scattered, depresso-globose, pierced with a simple minute 

 pore ; asci obovate-oblong, attenuated at the base into a short stem, 

 sporidia 8, subtriseriate, oblong, rounded at the ends, straight, uni- 

 septate, not constricted at the septum, epispore thick, 17 X 4-5 mic. 



On dead leaves of Iris jiseudacorus. Near Shrewsbury, Nov. 1873. 



12. Sphaeria (Delitschia) Winteri. n. s. 



Perithecia immersed, spherical, black; ostiolum elongated, cylin- 

 drical, tuberculose, rugnlose, frequently somewhat curved ; asci 

 cylindrical, octosporous. Sporidia involved in mucus, uniseptate, 

 black-brown, elliptical. 



On rabbits' dung. North Wootton, Dec, 1873. 



The perithecia are completely immersed in the matrix, only the 

 tip of the ostiola being visible. The sporidia are at first greenish- 

 yellow, then clear brown, becoming eventually almost black, when 

 young surrounded by a gelatinous envelope, which subsequently 

 disappears. They exhibit a tendency to fall in halves at the septum, 

 •003 in. long by -001 in. wide (-062 m.m.--028 m.m.). 



Dr. George Winter, to whom specimens were submitted, con- 

 siders it distinct from all its allies, and adds, " it approaches nearest 

 to D. chcetomoides, Karst., Fungi Fennici. Exs.

 Sphariacei Brit. Cent. it. (inedit.) 



On dead stems of Solarium dulcamara, in company with a Hen- 

 dersonia, which doubtless bore some connexion with it, as a second- 

 ary form of fructification.
