282 MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPHÆRIÆ. 
175. S. (NECTRIA) COCCINEA, Pers. ; Fr. S. M. ii. p. 412. Ta». XLIX. figs. 174 and 175, 
ascus with sporidia, and free sporidia, X 325. Sporidia almost always uniseriate, 
colourless, uniseptate, frequently with a nucleus in each septum, elliptical, subacu- 
minate, 0:0005 inch long. In the variety “ sanguinella”” I did not find any difference 
in the fruit, except that the average size of the sporidia was somewhat smaller, 
Fig. 175 represents free sporidia of the variety * cicatricum,” Desm., x 450. 
176. S. (NECTRIA) CINNABARINA, Tode; Berk. Engl. Flora, No. 77, under * Sphæria.” 
Tas. XLIX. fig. 175, sporidia, x 450. Sporidia sometimes uniseriate, sometimes 
biseriate, normally I believe uniseptate, frequently if not always constricted in the 
middle, rather pointed at each end, colourless or pale sea-green, 0:0004 to 0:0006 
inch long. I found some sporidia attached to long threads; but whether they were 
in the nature of stylospores, or whether the threads were the product of germination, 
I cannot say. Several of the sporidia were biseptate. See a, fig. 175. 
177. 8. (NECTRIA) DECOLORANS, Pers. Syn. p. 49. Tas. XLIX. fig. 176, ascus with spo- 
ridia, and free sporidia, x 325. Sporidia uniseptate, colourless or greenish, 0:0005 
inch long. Placed by Fries under S. cinnabarina, from which it differs in its more ` 
compact habit and in the more broadly elliptical sporidia ; the perithecia, however, 
are rugged as in that species, with which perhaps it ought to be united. 
178. S. BERBERIDIS, Pers.; Fr. S. M, ii. p. 415. Tas. XLIX. fig. 177, sporidia, X 325. 
Sporidia uniseriate, but so overlapping as to be almost biseriate, yellow when young, 
brown when mature, constricted in the middle, usually acuminate at the ends, 0:0011 - 
to 00016 inch long. Quiere if distinct from S. Laburni ? 
179. S. (NECTRIA) CUCURBITULA, Tode; Fr. S. M. ii. p. 415. Tap. XLIX. fig. 178 a, 
sporidia ; b, spermatia ; and c, caudate irregular bodies : all x 325. Sporidia colour- 
less, irregularly elliptical, 0:0004 inch long. Two membranes very visible in the 
sporidia. Besides the normal asci and sporidia, the perithecia produce asci containing 
the spermatia-like bodies (5) on the right: and the caudate bodies on the left also 
appeared to proceed from the same perithecia; but of this I am doubtful. The 
length of the spermatia is 0-0001 to 0-0002 inch, of the caudate bodies 0:0006 
- inch; what the latter may be I cannot say. 
180. S. LABURNI, Pers. Syn. p. 50. Tas. XLIX. fig. 179, ascus, x 225, and free sporidia, 
x 450. Sporidia, when perfect, multicellular, dark clear brown. I find in different 
perithecia in the same stroma every gradation from colourless minute unicellular 
spores (mostly with a nucleus at each end), through septate, biseptate, and triseptate 
forms, up to the multicellular. The colour varies by degrees, being at first colourless, 
then green, and eventually dark clear brown. 
181. S. PULICARIS, Fr. S. M. ii. p. 417. Tas, XLIX. fig. 180, ascus with sporidia, and 
free sporidia, x 325. Sporidia biseriate, colourless, elliptical, sometimes pyriform, 
pseudo-triseptate from division of the endochrome, 00006 to 0:001 inch long. - 
= (Nzorria) Purton, Grev. Tas. XLIX. fig. 181, ascus with sporidia, X "n 
poridia uniseriate, colourless, acuminate, elliptical, 00004 inch long. Fries Jo 
this species with S. Abietis; I do not know why, as it is quite distinct in habit and 
fructification,
