MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPHÆRLÆ. 
piercing the bark by their long converging necks, forming compact scattered black 
pustules on oak-branches. On dead and decaying branches of oak at Weybridge, 
September, 1856. Much resembling SpA. verrucæformis in its external form, and in 
the very glutinous nature of the contents of the perithecia. 
S. (DIATRYPE) NUCLEATA, n. s. Tas. XLVI. fig. 76, ascus with sporidia, x 395. 
Sporidia linear-acuminate, but constricted in the middle, colourless, 0:0007 to 00008 
inch long. Perithecia ovate or globose, with rather short ostiola, collected in elon- 
gated irregular patches surrounded by a dark line. Weybridge, J anuary, 1856, on 
furze. 
S. (DIATRYPE or VALSA) VARIANS, n. s. Tas. XLVI. fig. 77, ascus with sporidia, x 
325. Sporidia biseriate, obtuse, constricted in the middle, colourless, with granular 
endochrome, uniseptate, 0-0006 inch long. Perithecia subglobose; ostiola conical, 
sometimes umbilicate at the apex. The masses of perithecia penetrate the bark in long 
parallel lines. This plant unites the characteristics of the Circumscriptee and Lig- 
nose, some specimens having a conceptaculum, and others being scattered, with a 
black line and without a conceptaculum. Eltham, June 1855. 
S. (DIATRYPE or VALSA) DENIGRANS,n.s. TAB. XLVI. fig. 78, ascus with sporidia, x 
325. Sporidia uniseriate, often partly overlapping, dark olive-brown, elliptical, bi-, tri-, 
or multi-nucleate, sometimes quite simple, 00005 inch long.  Perithecia conical or - 
depressed, with long ostiola, deeply set in the wood; ostiola penetrating the bark and 
raising the wood into minute but prominent black tubercles. When a nest of perithecia 
Is cut transversely, there is a black line round them which is very well defined. 
8S. (DraTRYPE) INÆQUALIS, n. s. Tas. XLVI. fig. 79, ascus with sporidia, x 325. 
Sporidia uniseriate, almost colourless, but rather of a green tinge, obtuse, constricted 
in the middle, uniseptate, 0:0006 inch long or a little over; contents granular and 
nucleate. Perithecia subglobose ; ostiola short and rugose. The surface of the wood 
(beneath the epidermis) under which the perithecia lie is blackened and rugged; the 
perithecia are sometimes scattered. Masses of perithecia surrounded by a black 
line. Nearer to the Lignosæ than to any other division. On furze, Weybridge, 
January 1856. 
S. (DraTRYPE) BaDHAMI, n. s. Tar. XLVI. fig. 80, ascus with sporidia and free spo- 
ridia, x 325. Sporidia biseriate, colourless, usually 4-nucleate, with a minute hyaline 
appendage at each end (which, however, is invisible in the asus), narrowly almond- — — 
shaped, 0°0005 to 0:0006 inch long without the appendages. The perithecia occur - 
we and in masses ; they are deeply imbedded in the wood ; the surface of the inner 
bark is much blackened. The plant in habit and appearance resembles S. inequalis, 
supra; but the sporidia are altogether different. |

with sporidia and free sporidia, x about 225. Sporidia very numerous, crowded, ae 
yellowish in the mass, almost colourless when
