MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPHARIA. 
probably not a true Spheria. In specimens in my own herbarium from Tunbridge 
Wells, each pulvinulus is seated upon a dense white byssoid subiculum, which 
becomes brown with age. 
S. (HYPOXYLON) VERNICOSA, Schwein. Tas. XLV. fig. 34, ascus with sporidia,.x 315. 
Sporidia uniseriate, dark brown, elliptical, 0-0005 to 00006 inch long. Perhaps only 
a form of S.concentrica; but Mr. Berkeley considers it distinct in the structure 
of the stroma. 
S. (HYPOXYLON) ARGILLACEA, Fr. Obs. i. t. 2. f. 5. Tas. XLV. fig. 35, ascus with 
sporidia, x 325. Sporidia uniseriate, opaque black-brown, irregularly elliptical ;. 
sometimes one, two, or three nuclei, or a number of small nuclei, are visible. 
S. (HYPOCREA) RUFA, Pers. Fr. S. M.ii.p.335. Ta». XLV. fig. 36, ascus with sporidia, 
x 325. The sporidia are squarish colourless bodies usually 16 in each ascus, quite 
unlike the usual fructification in the Pulvinatæ. This plant agrees in its fructifica- 
tion with S. citrina and S. lobata, and, like S. gelatinosa and some others, comes 
very near to Dothidea; for the perithecia, as far as I can make out, have no walls 
distinct from the flesh of the stroma; so that the fructifying mass is in fact a 
* nucleus" in the sense in which that word is used in Dothidea. 
S. PRUINATA, Kl. Linn. vol. viii. p. 489. Ta». XLV. fig. 37, ascus with sporidia, x 325. 
Sporidia uniseriate, dark brown, elliptical, with 1 to 4 nuclei, or with a dark curved 
band across, arising, I think, not from a septum, but from the approximation of the 
nuclei; varying slightly in length, but on an average 0:001 inch long. Perithecia 
crowded, dome-shaped, with mammillate ostiola, mostly, but not always covered with 
a white farinaceous powder. 
S. (HYPOXYLON) FUSCA, Pers. Fr. S. M. ii. p.332. Tas. XLV. fig. 38, asci with - 
sporidia, x 325. Sporidia elliptical or almond-shaped; when young pale brown, with 
one or two large nuclei, and sometimes small nuclei also; when ripe very dark and 
opaque, normally uniseriate, but occasionally erowded as shown in fig. 39, which 
represents the fruit (x 225) of a Sphæria not differing materially from Sphæria 
fusca, except that the sporidia are larger and more irregular than usual. De, 
latter plant occurred at Eltham, in Kent, in J une, 1855. The ordinary length of the 
sporidia in S. fusca=0-0005 inch. | 
S. (HYPOXYLON ?) PARMULARTA, Berkel. Tar. XLV. fig. 40, sporidia x 225. Sporidia 
rather dark brown, clear, with mostly one nucleus, irregularly elliptical or almond- 
shaped, 0-0004 inch long. The specimens are in a bad state; and I had some doubt 
whether the plant ought not to be referred to the Connatæ or Confluentes. There B 
however, some appearance of the débris of a Pulvinulus. i 
S. (Hrroxyuon) COHÆRENS, Pers. Fr. S. M. ii. p. 935. Tap. XLV. fig. 1 
with sporidia, x 325. Sporidia uniseriate, rather dark brown, irregularly elliptical, 
ee rather curved, often with one or two nuclei, 0:0003 to 0:0004 inch 
ong. 
S. (HYPOXYLON) RUBRICOsA, Fr. E]. 2. p.63. Tap. XLV. fig. 42, ascus with sporidia, 
x 325. Sporidia uniseriate, dark brown, eventually opaque, elliptical, uniseptate, 
with frequently a nucleus in each division, 0:0004 to 0-0006 Bid long.
