284 MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPHÆRLÆ. 
with sporidia, x 325. Sporidia crowded, colourless, broadly almond-shaped, 0:0007 
to 0:0009 inch long. 
192. SPHÆRIA MUTILA, Fr. S. M. ii. p. 424. Tas. 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. SPHÆRIA MEGALOSPORA, Mont. Sylloge, p.229. Tas. 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. SPHÆRIA INSIDENS, Schw.? Tag. 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. SPHÆRIA MELOGRAMMA, Pers.; Fr. S. M. ii. p.420. Tap. XLIX. fig. 194, sporidia, 
x 450. Sporidia biseriate, arcuate, acuminate at both ends, triseptate, pale greenish 
brown, probably ultimately clear dark brown, 0:0014 to 0-002 inch long. 
196. SPHÆRIA CALYCANTHI, Fr. (sed qu. Schwein.), S. M. ii. p.421. Ta». 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 0:0011 inch long. 
197. 8. (DIATRYPE) DECIPIENS, Dec.; Fr. S. M. ii. p.371. Tag. XLIX. fig. 196, sporidia 
. highly magnified. I could find 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. ; Fr. El. ii. p. 86. Tas, 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. ! 
1984. SPHÆRIA CHRYSENTERA, n.s. Perithecia 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, nof (T think) septate, although the endochrome is always 
divided into two distinct portions, frequently into four, 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 a 
re sometimes seated on a byssoid subiculum, which made 
me doubt to which division it should be referred.

99. J P Fr. Tas. XLIX. fig. 199, sporidia, x 325. Sporidia biseriate, yellowish- 
own, linear-ac te, 3-septate, 0:0012 inch long, hardly distinguishable from the
