2674. Sph^eHa fn tills. B. ^ Br. " Blackened rose "ph^ria." 



Scattered, covered by the blackened cuticle ; perithecia sub- 

 globose ; asci linear ; sporidia uniseriate, short, oblong-elliptic, 

 uniseptate. — B. ^ Br. Ann.N.H. no. 638, 1. 11,/. 23. 



On dead rose twigs. Mar. King's Cliffe. 



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

 black specks. Asci linear ; sporirlia uniseriate, short, oblong'-elliptic, hya- 

 line, sometimes slightly constricted in the centre, uniseptate. The septum 

 appears to be continued through the external as well as the internal mem- 

 brane. The sporidia have much the form which is so common in Diplodia.

SphaBria." 



Perithecia depressed, covered ; ostiola obscure ; asci linear,

On dead twigs of Cornus. Jan. Spye Park. 



Penthecia covered by the cuticle, depressed, moderately large ; asci cylin- 

 drical, elonj^ated ; sporidia uniseriate, oblong-elliptic, very obtuse, unisep- 

 tate, slightly constricted at the commissure (•0005 in.) "0125 m.m. long ; pa- 

 raphyses linear, some of tliem containing one or two sporidia. The cuti' le

On privet, elder, bramble, &c. [Low. Carolina.] 



Very variable, especially in the size of the sporidia. A form occurs on 

 bramble stems with the a?ci usually tetrasporous (Cooke Seem. Journ. 18G6,
