tlie two, judging from specimens sent to Dr. Hooker: and, consequently, 

 I should feel inclined to refer the *S'. dlsciformis of FL Ed. to S, 

 h'dllata, though the plant figured in the Sc. Crypt. FL is unquestionably 

 the true species. Variolaria punctata^ Bull, t, 432. f. 2. appears to 

 me to represent *S'. hullata. 



33. S. dspera, Fr. {j'oiigh Splicerici) ; orbicular or angular 

 convex black, perithecia attenuated into a slender neck covered 

 with a dirty-white stroma, ostiola conico-cylindrical. Fr, 

 Sijst, Myc. V. 2. p. 354. S. erecta, Purt. ! v. 3. n. 1529. 



On branches of oak, &c. Common. — Very much resembling S. ver- 

 ruccpformis, but the stroma is dirty-white, the ostiola more prominent, 

 and the neck, instead of being short, attenuated. 



34. S. favdcea, Fr. (Jioney-comh Sphceria) ; irregular black, 

 perithecia oblong-ovate with a short neck covered with the 

 thin dirty-white stroma, ostiola rather prominent convexo-sub- 

 rotund. Fr. Obs. Myc. 2. t.^.f, b. Syst. 3Iyc. v. 2. p. ^b^.

On birch yet covered with bark. Dumfries-shire. Dr. Greville. — 

 *^ Sometimes orbicular, sometimes irregular from several individuals 

 being confluent, prominent, 2 — 4 lines or more broad, at first pale wood- 

 colour. Perithecia disposed indistinctly in two layers, larger than in 

 the neighbouring species, their bases subconnate, apices distinct, covered 

 vv'ith a thin stroma, which is in the old state obliterated. Base circum- 

 scribed by a fine black line." Fr. I. c. 



35. S, verruccEformis, Ehr. (ivart-Uhe SphcBrici) ; angular con- 

 vex rugose black nearly of the same colour within, circum- 

 scribed below, perithecia ovate with a short neck. Pers. Syn, 

 p. 26. Fr. Syst. Myc. v. 2. p. 355. Scler. Sued n. 74.

On branches of hazel, beech, &c. Very common. — Bursting through 

 the bark by the laciniae of which it is surrounded, 1 — H line broad black, 

 brownish within, the orifices of the perithecia more or less distinct, in 

 the specimens published in Scler. Succ. distinctly visible to the naked 

 eye, sometimes, however, very indistinct. 



36. S. fiavo-virens^ HofFm. {ijellow-green-fleslied Sphceria) ; 

 unequal rugose black within pulverulent yellow-green, peri- 

 thecia globose, ostiola rather prominent punctiform. Pers. Syn, 

 p. 22. Moug. 8^ Nest. ! n. 375. Fr. Syst. Myc. v. 2. p. 357.

On branches of trees either covered with the bark or decorticated. — 

 A most variable species, but always easily distinguished by the peculiar 

 colour of the stroma. — iS. appears at first sight very different, being 

 covered by the wood which is raised up. Sp. multiceps. Sovv'., regards 

 the more common form of the species, as appears from the figured 

 specimen, but he was well acquainted also with the variety.
