316 MR. F. CURREY ON THE FRUCTIFICATION OF SIMPLE SPHÆRIÆ. 
to 0:0026 inch long. I suspect that the sporidia of S. hirsuta, and perhaps also those 
of Spheria ovina and Sphæria canescens, are multiseptate when perfect. 
231. S. ovina, Pers.; Fr. S. M. ii. p.446. Fructification not distinct from that of $ hip. 
suta (post). I have found, however, on one or two occasions specimens which I be. 
lieve to be S. ovina, in which the sporidia exhibit under the microscope a peculiar 
pink tinge, each sporidium being also furnished with a clear, round, colourless spot. 
Tas. LVII. fig. 16, represents the fruit of this form x 325 diams. 
232. S. CJESIA, Carm. Ta». LVII. fig. 17, ascus with sporidia highly magnified, Sporidia 
(? always) uniseriate, colourless, elliptical, or subpyriform, about 0-0002 inch long. 
Perithecia white, very hairy. This specimen is marked “S. ovina statu juniori;” but 
whoever so named it, had clearly not compared the fruit of the two species. 
233. S. HIRSUTA, Fr. S. M. ii. p. 449. Tas. LVIL fig. 18, ascus with sporidia, x 220, 
Sporidia biseriate or crowded, pale brown, long, flexuous, 0:002 to 0:0026 inch long. 
See remarks under §. Racodium (supra). 
234. S. RHODOCHLORA, Mont. Syll. p.227. Tas. LVII. fig. 19, ascus with sporidia, x 395. 
Sporidia crowded, colourless, broadly elliptical, with a reticulated appearance, but 
whether from the spores being multicellular, or from a number of nuclei touching 
one another, I cannot say; 0-0005 to 0:0007 inch long. 
235. S. MUTABILIS, Sz. Tas. LVII. fig. 20, ascus with sporidia, x 325. Sporidia bise- 
riate, colourless, curved, acuminate, endochrome 4-partite, 0°0008 inch long. Very 
like S. pulvis-pyrius to the naked eye, but under a power of 50 diams. the perithecia 
exhibit a very slight brownish hairiness, principally at the base. — | 
236. S. PILOSA, Pers.; Fr. S. M. ii. p. 440. Tas. LVII. fig. 21, ascus with sporidia, X 
about 325. Sporidia uniseriate, colourless, elliptical, uniseptate, or with the endo- 
chrome bipartite, 0:0003 to 00004 inch long. A small Sphæria, like S. pulvis- 
pyrius, but decidedly hairy.
