376 Rev. M.J. Berkeley and Mr. C. E. Broome on British Fungi, 



422*. S. mutica, n. s. Erumpens, peritheciis globosis obtusis 

 subcsespitosis ; sporis minimis ellipticis vel obovatis hyalinis. On 

 small branches of elder, Batheaston, C. E. Broome. 



Erumpent. Peritbecia more or less csespitose, globose, blunt, 

 black, shining. Spores very small, hyaline, elliptic or obovate. 



This has exactly the habit of a Diplodia. 



423. S. Candollii= Spharia Buxi, DeC. El. Fr. vol. vi. p. 146 ; 

 Berk. Fung. n. 180, quoad specimina provectiora. SeptoriaPha- 

 cidioides, Desm. no. 1719. 



The spores in this species are hyaline, oblong, about twice as 

 long as broad, varying from elliptic to obovate. 



424. S. thecicola, n. s. Superficialis convexa collabescendo 

 rugosa ; sporis tenuissimis linearibus rectis. On thecse of Poly- 

 trichum piliferum, Aberdeen, Dr. Dickie. 



Perithecia black, scattered, convex, at length collapsing, open- 

 ing by a definite orifice. Spores very slender, hyaline, linear, 

 straight, of various lengths. 



The spores in this species are longer and more slender than in 

 S. cylindrospora, and resemble those of such Septoria as S. Le- 

 pidii. Spharia emperigonia, Auerswald in Rab. no. 850, which 

 grows on a Polytrichum, has asci with subcymbiform uniseptate 

 spores, and is therefore a true Spharia. 



425. S. menispora, n. s. Tecta ellipsoidea nigra poro rotundo 

 demum pertusa ; sporis arcuatis longis ; nucleis globosis hie illic 

 sparsis. On dead leaves of Typha latifolia, Spye Park, Wilts, 

 C. E. Broome. 



Entirely concealed beneath the cuticle, with the exception of 

 the round ostiolum. Perithecia ellipsoidal, black. Spores very 

 long, curved, acute at either end, containing many scattered 

 globose pellucid nuclei. 



The nuclei are not arranged regularly in a single row, and 

 therefore probably do not represent endochromes. 



Discella, n. g. 

 Perithecium spurium subsimplex supra quandoque obsoletum 

 vel omnino deficiens indeque excipuliforme ; sporis elongatis 

 simplicibus vel uniseptatis sporophoris suffultis. 



The perithecium in this genus is so little distinct from the 

 stratum of sporophores, that it is frequently difficult in examining 

 a slice under the microscope to say that it really exists, though 

 the two together are sometimes of considerable thickness ; neither, 

 on the other hand, is the limit between the external cells and 

 those of the matrix very accurately defined. In the same spe- 

 cies it is sometimes entirely wanting above, and the sporophorous 

 stratum merely covered by the cuticle, which at last splits and 

 exposes the excipuhfbrm disc, while in other cases the spurious
