284 MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPH^Rl^E. 



with sporiclia, x 325. Sporidia crowded, colourless, broadly almond-shaped, 0'0007 

 to 0-0009 inch long. 



192. Sph^eria mutila, Tr. S. M. ii. p. 424i. Tab. XLIX. fig. 191, sporidia, x 325. 

 Sporidia crowded, colourless, but with a greenish tinge ; endochrome divided trans- 

 versely, and frequently also longitudinally; sporidia irregular in shape, variable, 

 0-0008 to 0-0012 inch in length. 



193. Sph^bia megalospora, Mont. SyUoge, p. 229. Tab. XLIX. fig. 192, ascus with 

 sporidia, X 225. Sporidia uniseriate, rich dark brown, obtusely elliptical, constricted 

 in the middle, frequently slightly curved, 0-0016 inch long. 



194. Sph^ria INSIDENS, Schw.? Tab. XLIX. fig. 193, sporidia highly magnified. I could 

 find no asci. Sporidia pale clear brown, irregularly elliptical or subturbinate, 0-0003 

 inch long, or rather less ; on rough corky elm-bark, blackening the furrows with its 

 small perithecia. 



195. Sph^ria melogramma, Pers. ; Fr. S. M. ii. p. 420. Tab. XLIX. fig. 194, sporidia, 

 X 450. Sporidia biseriate, arcuate, acuminate at both ends, triseptate, pale greenish 

 bro^vn, probably ultimately clear dark brown, 0-0014 to 0-002 inch long. 



196. Spu-^ria Calycantht, Pr. (sed qu. Schwein.), S. M. ii. p. 421. Tab. XLIX. fig. 195, 

 ascus with sporidia, X 325. Sporidia crowded, colourless, hyaline, with one or many 

 nuclei, or none ; broadly almond-shaped, 0-0008 to 00011 inch long. 



197. S. (DiATRYPE) DECiPiENS, Dec; Pr. S. M. ii. p. 371. Tab. XLIX. fig. 196, sporidia 

 highly magnified. I could fuid no asci. Sporidia elliptical, varying much in length 

 and breadth, sometimes slightly curved, rather dark brown, 0-0003 inch long, crowded. 

 Ostiola stellate, just as in S. stellulata. 



198. S. (Diplodia) subsolitaria, Schwein. ; Pr. El. ii. p. 86. Tab. XLIX. fig. 198, spo- 

 ridia, X 325. This plant might be placed in the genus Diplodia, the sporidia being 

 borne on sterigmata, not produced in asci. Sporidia of a clear brown colour, 

 irregularly elliptical or subpyriform, pseudo-uniseptate from the division of the 

 endochrome. 



198 a. SPHiERiA CHRYSENTERA, n. s. Perithccia rounded, without any neck, crowded, 

 situated underneath the outer bark, which is thrown off sometimes irregularly, some- 

 times in rings. Contents of the perithecia yellow, Sporidia biseriate, bright yellow 

 when young, then a pale clear light brown, eventually darker brown ; irregular in 

 shape, usually somewhat acuminate at each end, always constricted in the middle, 

 the outline sometimes wavy, not (I think) septate, although the endochrome is always 

 divided into two distinct portions, frequently into fovir, and occasionally into three. 

 Length of sporidia, 0-0008 to 0-0009 inch. Weybridge, September 1856. Easily 

 known by the bright yellow colour of the contents of the perithecia, and by its pecu- 

 liar fruit. The perithecia are sometimes seated on a byssoid subiculum, which made 

 me doubt to which division it should be referred. 



Div. 15. Seriate. 



199. S. JuNCi, Pr. Tab. XLIX. fig. 199, sporidia, x 325. Sporidia biseriate, yellowish- 

 brown, linear-acuminate, 3-septate, 0'0012 inch long, hardly distinguishable from the
