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



Scattered, forming minute pustules ; perithecia depressed, sub- 

 globose, brown. Asci linear, containing eight sporidia arranged 

 in a single row; sporidia pale brown, oblong- elliptic, obtuse, 

 triseptate, by no means constricted at the articulation, sometimes 

 slightly curved. 



Distinguished from S. sepincola by its minute brown perithecia 

 and even elliptic obtuse sporidia. There is no sign of any ostiolum 

 externally, nor have we ascertained the existence of any. S. 

 Cornij Sow., which is usually referred to S. sepincola, has curved 

 simple reproductive bodies apparently without asci. At least, such 

 is the case with the specimens still remaining in Sowerby's Her- 

 barium. 



;S^. sepincola according to our notion of the species has slender, 

 somewhat clavate asci and biseriate, oblong, subfusiform hyaline 

 sporidia. Specimens may be found with slightly varying cha- 

 racters as to size and figure, but it is best to consider all which 

 agree in essential respects as forms of one species. We therefore 

 now refer the minute Sphmna found on dock-stems by Mr. Gar- 

 diner at Balmerino, formerly named S. Gardineri, to S. sepincola 

 as a minute form on herbaceous stems.

 magnified, but less so than in S. conformis. Fig. 21. S. sepincola : a. Ascus ;

637. S. (Obtectse) persistens, n. s. Sparsaligno adnata demum 

 cortice putrescente nuda subglobosa ostiolo parvo distincto ; ascis 

 clavatis, sporidiis biseriatis hyalinis fusiformibus centro con- 

 strictis curvulis sporidiolis quaternis. On dead shoots of rose, 

 Bedford Purlieus, King's Clifi'e, March 1850. 



Scattered over the branches, and so immersed in the bark as 

 not to form any pustules, exposed and persistent when the matrix 

 is decayed, globose with a minute distinct ostiolum. Asci clavate, 

 containing two rows of sporidia. Sporidia hyaline, fusiform, 

 straight when seen from behind, slightly curved when seen 

 laterally, constricted in the centre, each division containing two 

 globose sporidiola. Well distinguished by its persistent nature 

 and curious sporidia. We have not observed any septa.

 less magnified. 



638. S. (Obtectse) futilis, n. s. Sparsa epidermide nigrifacta 

 tecta; peritheciis subglobosis; ascis linearibus; sporidiis uni- 

 seriatis brevibus oblongo-ellipticis uniseptatis. On dead rose- 

 twigs. King's Clifi"e, March 1850. 



Minute, scattered, covered by the blackened cuticle so as to 

 present little black specks, Asci linear; sporidia uniseriate.
