On oak-wood in moist places. Cotterstock, Norths., Hev. M. J. 

 Berkeley. — Siibelliptic, parallel, 2 — 3 lines long, always furnished with 

 a circumscribing black line. Sporidia oblong-elliptic containing two 

 Sporidivla. Very much resembling small scattered specimens of S. 

 serpens. I am quite certain that S. parallehi, Sow., is not the present 

 species, and have little doubt that it is 6*. verrucoiformis. No specimens 

 indeed are named, but there arc one or two loose samples of that plant 

 in which the pustules are disj)osed in parallel rows, and are most pro- 

 bably what he had in view. Indeed his account, " the spherules are 

 imbedded in a blackish substance which rises above the burst cuticle^ 

 standing in little patches above it," is quite conclusive as regards its non- 

 identity with iS*. uda, but agreeing sufficiently exactly with S. verrucce- 

 fonnis. S. immersay Sow. ! t. 374./! 1. is S. leiojdaca, It. 



Div. 7. Versatiles. {Named from their intimate relation to 

 the species of the foregoing and succeeding divisions.) Determinate^ 

 connate, not circumscribed, Perithecia scattered through the 

 stroma.

 prominent irrop^ular clianging- from brown to black, light 

 reddish-brown \yithin, ostiola latent. Sow. t. ^lA.f. 9. Part. !

On dead branches of Elm. May — Nov. Not rare, according to 

 Purton. — *'From the size of a pea to that of the largest hazel nut. Firmly 

 attached by a broad base, or free round the edge \\ith a thick stem, the 

 whole resembling a stud or clumsy button, irregular, semiglobate 

 flattened, circular or oblong." Part. JSISS. Certainly not circum- 

 scribed at the base. 



39. *S'. quercina, Pers. {oah-bark Sphcrria) ; erumpent sub- 

 orbicular convex reddish-brown, at lengtli black, nearly of tlie 

 same colour within, ostiola ratlier prominent four-sided. Pers.

On oak branches. About Edinburgh, occasionally. Pr. Greville. 

 It lias also been found by iMr. Baxter. 1 liave seen no English speci- 

 mens. — This requires to be carefully distinguisheil from S. verritccc- 

 forinis, from wiiich it is known in every stage of growth by the absence 

 of the circumscribing black line. 1 suspect from Dr. Johnston's 

 dcscri[)tion and from the transmission of specimens to Ur. Hooker, tb.at 

 his S. quercina is S. leiphcnnia.
