318 MR. F. CURREY ON THE FRUCTIFICATION OF SIMPLE SPHJERLE. 
to Oryptogamic Botany,’ p. 281, Mr. Berkeley figures the sporidia of S. pulvis-pyrius 
with as many as five septa, and of a more elongated form than in my figure. In all 
the specimens (and they are very numerous) which I have examined, I have never 
found more than three septa, nor have I ever seen the sporidia so elongated as in — 
Mr. Berkeley’s figure. Mr. Berkeley himself mentions the sporidia as being trisep- 
tate in ‘ Ann. and Mag. of Nat. Hist.’ ser. 2. vol. vii. p. 189. 
249. S. CONGLOBATA, Fr. S. M. ii. p. 444. Tas. LVII. fig. 33, ascus with sporidia, and free 
sporidia, x 325. The specimens of this Spheria in Hook. herb. show clearly that 
this species is only a crowded, subcuticular, erumpent form of S. pulvis-pyrius. Some 
of the perithecia are bursting transversely, some longitudinally, and others form 
cæspitose masses; others again have the ordinary scattered habit of S. pulvis-pyrius. 
They form a very instructive series of specimens. 
250. S. DIOICA, Fr. S. M. The specimens of this plant in Hook. herb. show clearly that 
(like S. conglobata) this species is only a subcuticular form of S. pulvis-pyrius. 
251. S. MOROIDES. n.s. Tab. LVII. fig. 34, ascus with sporidia, and free sporidia, x 325. 
Sporidia biseriate, greenish brown at first, eventually brown, subhyaline, elliptical, | 
0:0004 to 00005 inch long. Perithecia rugose, small, like very small specimens of 
S. moriformis, from which species the present differs altogether in the nature of its — 
sporidia. 
252. S. PLATEATA, Pers. in litt. Tas. LVII. fig. 35, ascus with sporidia, x 325. Sporidia 
crowded, yellowish brown, multipartite, subelliptieal, 00008 to 0:0010 inch long. 
On wood. Very like S. pulvis-pyrius, except in the sporidia—possibly only a small - 
form of S. Spartii, Nees, which latter does not differ essentially from S. elongata, Fr. 
253. S. SPERMOIDES, Hoffm.; Fr. S. M. ii. p.457. Tas. LVII. fig. 36, ascus with sporidia, 
and free sporidia, x 325. Sporidia biseriate, colourless, curved, endochrome some- 
times bipartite, 0-0008 inch long. 
254. S. MAMMÆFORMIS, Pers.; Fr.S. M. ii. p. 455. Tan. LVIL. fig. 87, sporidia, x 450. 
Sporidia dark clear brown, subcymbiform, varying much in size, from 0:0008 to 
00016 inch long. e 
255. S. srERCORARIA, Sow.; Fr. S. M. ii. p. 455. Tan. LVIL fig. 38, ascus with sporidia, 
X 220. Sporidia uniseriate, brown, eventually quite opaque, at first colourless, ellip- — 
tical, or almond-shaped, 0-0016 to 0-002 inch lono. B 
256. S. STERCORARIA, Sow. var.? I subjoin here a description of a Sphæria which I ha 
. found growing on horse-dung, and which is probably the same species as the last, 
notwithstanding its smaller sporidia and curious ostiola.  Perithecia solitary, or few 
together; ostiola formed of a number of processes arranged in a penicillate manner, 
each consisting of a single row of irregularly-shaped cells, the upper cell being 
pointed. Sporidia mostly uniseriate, but sometimes biseriate, greenish at first, then 
darker, probably eventually black, elliptical, 0-0010 inch long. Tas. LVII. fig. 39 (a) 2 
represents an ostiolum broken off, x 325 diameters, and fig. 39 (5), an ascus vid 
sporidia similarly magnified. |
