256 FUNGI. [Spharta. 



On stems of Pte7-is aquilina. — Common ; but every black spot oc- 

 curring on the stems of ferns is not to be presumed to be this species. 

 At first even, at length dotted with the perithecia. S. pteridis, Sow. ! 

 is Lepto&troma filicinum. 



93. >S'. Junci, Fr. {Rush SphcBiia) ; covered, at length burst- 

 ing forth by longitudinal chinks between the fibres, tubercu- 

 lated, perithecia in rows black witiiin, at first immersed in the 

 black stroma. Fr. Si/sL Myc. v. 2. p. 428. Scler. Suec. ! n, 

 5. Jo/uisL! FL Berw, 2. p. 119. 3Iouff. Sf Nest; n. 9Qi, 



On stems o^ Juncus conglomeratus, &c. Common. 



94. S. stricefdrmis, Fr. {striceform Sphmria) ; covered with 

 the innate blackened epidermis, at length bursting in the midst, 

 lanceolate short acute, perithecia in rows mouthless filled with 

 white jelly. Fr. Syst. Myc.v. 2. p. 428. Scler. Sued n. 195. 



On the dead stems of larger herbaceous plants. Apethorpe. Norths., 

 liev. M. J. Berkeley — Fries remarks that various species are called by 

 this name, and in consequence he has quoted no synonyms. My speci- 

 mens are the same with those published by Fries and like them grew 

 on the stem of some umbelliferous plant. Dr. Greville's species appears 

 different, and I therefore subjoin his character. " Black gregarious 

 forming linear or oblong striae smooth ; spherules very minute without 

 obvious mouths." Fl. Ed. p. 357. '• StricB half a line to above a line 

 long parallel. Spherules globose apparently without orifices and quite 

 concealed within the receptacle." 



95. S. aru7idindcea, Sow. (compound reed Sphceria) ; erum- 

 pent linear with scarcely any stroma, perithecia in 1 — 2 rows 

 connate with a very obsolete ostiolum, black within. Sow. ! t, 

 336. Fr. Syst. 3Iyc. v. 2. p. 429. Purt. v. 3. p. 287. \ 



On stems of reeds which have lost the sheathing bases of the leaves. 

 Common. — In my specimens the contents o( the perithecia are white. 



96. S. nebidosa, Pers. (cloud-like Sphceria) ; covered, peri- 

 thecia very minute gregarious forming interrupted grey cloud- 

 like sublongitudinal spots, ostiola rather prominent acute.

Cryptosphceria 7iebulosa, Grcv. Fl. Ed. p. 362. 



On the smooth stems of herbaceous plants. Common. — Easily 

 known by its long grey patches dotted with the ostiola. S. maculans. 

 Sow., at first sight resembles this species, but the blackish patches cer- 

 tainly do not belong to the perithecia, which are indifferently scattered 

 all over the matrix, which is the leaf, I believe, of a Sparganiian. 



97. S. longissima, Pers. {linear Sphceria) ; covered black, 

 perithecia minute running together into extremely long parallel 

 rows; ostiola obsolete. Pers. Syn. p.Q\. Fr. Syst. Myc. v. 

 2. 7?. 431. Scler. Sued n. 194. JoJmst. Fl. Beriu. v. 2. p. 127. 



On stems of umbelliferous plants. Near Berwick, Br. Johnston 



Known by the narrow linear, black patches, extending from joint to 

 joint. I have never met with the perfect plant, but have found what
