Entirely covered, with the exception of the minute ostiolum, which pene- 

 trates the cuti<^le. Perithecia subglobose ; asci clavate, elongated; sporidia 

 biseriate. oblong, slightly curved, very obtuse triseptate, sometimes con- 

 Btricted at the articulations, dark brown. Allied to S. herharum, but with 

 different fruit.— j5. d' Br.

Perithecia globose, depressed, growing beneath the cuticle ; 

 ostiola papillteform ; sporidia oblong-cymbiform, quadriseptate, 

 articulations torulose. — A7in. N.H. no. 980, t. 17./. 33.

Perithecia subcuticular ; ostiola papillffiform, black ; asci clavate ; sporidia 

 (•001-"0012 in.) •025-*0.3 m.m., biseriate, quadriseptate, oblong, somewhat 

 cymbiform, joints swollen, endoehrome of a pale golden-brown. — B. d: Br. 



2697. Sphaeria tenebrosa. B. 4- Br. " Burdock Sph^ria." 



Scattered, covered by the cuticle and subjacent cells ; peri- 

 thecia depressed ; asci large, cylindrico-clavate ; sporidia brown, 

 bipartite, articulations subconic, with two endochronies. — B. 4"

On dead stems of Arcimm, which are blackened thereby. May. 

 King's Cliffe. 



Perithecia scattered, irregularly covered by the cuticle and subjacent cells, 

 which are traversed by dark, cellular mycelium, which here and there gives 

 rise to short toruloid threads. Asci large, cylindrical, obtuse, slight, at- 

 tenuated below. Sporidia biseriate, composd of two apposed irregular cones, 

 which contain at first a single large globule, but at length have two irregular 

 endochromes. Remarkable for its curious mycelium and large sporidia. 



2698. Sphaeria palustiris. B. 4- Br. '' Tailed spore 



Sphseria." 



Covered ; perithecia globose ; ostiola minute, papillseform, at 

 length opening with a round aperture ; asci linear ; sporidia 

 elliptic, slightly curved, uniseptate, appendiculate at either end.

On dead leaves of Iris, Carex, &c. Dec. 



Scattered, completely covered by the cuticle, globose at first, with a 

 minute papillseform ostiolum, at length opening with a regular round aper- 

 ture, the edges of which adhere closely to the matrix. Asci linear; sporidia 

 uniseriate, or rarely biseriate, from slipping over each other, cymbiform, 

 brown, uniseptate, furnished at either end with a hyaline appendage, rather 

 phorter than the joints, at length ejected, and forming a brown border to 

 the ostiolum. Sometimes the two cells of the sporidia appear like two ap- 

 posed cones. — B. (Sf Br.
