67. S. leijyhcemia, Fr. (wood- coloured Sphccrici) ; pustulate, 

 stroma cortical pallid as well as the erumpent disc, ostiola

On dead oak branches. Durham. Hook. Herb. Neighbourhood 

 of Berwick. Johnston, sent to Dr. Hooker under the name of S. ver- 

 TUCtF.formis. Purton. — When the epidermis is stripped off, the bark 

 appears raised into round even pustules with a distinct pallid yellowish 

 disc, entirely destitute of any conceptaculum by which it is distinguish- 

 able from species of the foregoing division and especially from S. tuleola. 

 The pustules at length acquire a blackish tinge. 



68. S. turgiday Pers. {tumid beech Sphceria) ; pustulate,peri- 

 thecia globose nearly erect close, ostiola obtuse convex at length 

 exserted from a minute narrow disc. Pers. Obs. Myc. v. 1.

On branches of beech. Common. — The branches on which it grows 

 and which it generally surrounds are of a bright red-brown. T\\e j^^ri- 

 thecia vary in size, and in the number grouped together, which is from 

 3—8, their ostiola collected in an erumpent brown disc. Most of the 

 British specimens I have seen marked as the present species are /S*. 

 quaternata. Indeed, Moug. ^- Nest. n. 1/9, appears to me to be that 

 species. 



69. S. salicina, Pers. (Willoio Sphceria); pustulate, peri- 

 tliecia globose disposed in circles, disc at length white pierced 

 with one or two pores, ostiola globose very minute at length 

 exserted. Pers. ! Syri. p. 47. Fr. Syst. Myc. v. 2. p. 401.

On willow twigs. Common. — " Perithecia distinct, thin, minute, 

 about eight in every circle, their necks united into a minute waxy slightly 

 promine^it disc, which is at first dingy, then white pierced with a black 

 pore, when it is very like S. leucostoma, but when perfect, the disc is 

 obliterated by the shining globose ostiola." Fr. I. c. — S. salicinay 

 Part. 3Iidl. FL, according to specimens before me, is Phacidiura car- 

 hoRacewu. 



70. ♦S'. ambie?is, Pers. (ambient Sphceria) ; perithecia im- 

 mersed disposed in circles, ostiola even subglobose surrounding 

 a dirty-white waxy disc. Pers. Syn. p. 44. Fr. Syst. Myc,

On branches of various trees, but especially Rosacece. Very 

 common. — Sporidia oblong curved. Varying much in size, in the 

 degree of elevation above the general surface, and the colour of the disc, 

 which is sometimes jet-black. aS. ambiens, Johnst. I Fl. Berw.^ is 

 Cytispora carphosperrna.
