MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPH^RI^. 277 



free sporidia, x 325. Sporidia biseriate, elliptical, sometimes acuminate, sometimes 

 obtuse at the ends, colourless, O'OOll to 00016 inch long. In some sporidia the 

 endochrome was broken up iato two, three, or six portions, but, I thinlc, only from 

 being dry. 



132. S. (Vaisa) profusa, Fr. S. M. ii. p. 392. Tab. XLVII. fig. 128, sporidia, x l-5() : 

 a, a yoimg sporidium almost colourless or very slightly greenish ; b, a sporidiuni 

 more advanced ; c, a ripe sporidium. The sporidia when yoimg have a gelatinous 

 envelope, which disappears in age, the asci frequently containing only fom- sporidia 

 arranged in one contiauous series ; I believe, however, the normal number to be 

 eight, and that they are sometimes arranged biseriately. The asci are absorbed at a 

 very early period, so that usually only free sporidia are to be found. These when 

 ripe are of a clear rich olive-brown colour with a very slight greenish tinge, oblong- 

 elliptic, 0-001 to 0002 inch long. One of the most beautiful Sphcerice in point of 

 fructification. 



133. S. (DiPLODiA ?) RUDis, Fr. El. ii. p. 98. Tab. XLVII. fig. 129, fruit, X 325. No 

 asci ; sporidia (? stylospores) rather dark brown, broadly elliptical, but slightly con- 

 stricted in the middle, O'OOIO to 0-0011 inch long. 



134. S. (Valsa) MICROSTOMA, Pers. ; Fr. S. M. ii. p. 388. Tab. XLVII. fig. 130, ascus 

 with sporidia, and free sporidia, x 325. Sporidia biseriate, colourless, transparent, 

 curved, obtuse at the ends, 0-0005 to 0-0007 inch long. 



135. S. (Vaisa) dissepta, Fr. S. M. ii. p. 392. Tab. XLVIII. fig. 131, asci with sporidia, 

 and free sporidia, x 325. Sporidia biseriate, colourless, linear-acuminate or almond- 

 shaped ; endochrome bi- or quadripartite ; 0-0004 to 0-0005 inch long. 



136. S. (Vaisa) circumscripta, Fr. ; Mont. Syll. p. 220, under " Valsa." Tab. XLVIII. 

 fig. 132, sporidia, x 325. Sporidia biseriate, colourless, linear, pointed at the ends ; 

 endochrome bipartite, sometimes quadripartite ; 0-0006 inch long. This agrees with 

 Montague's description, except that he caUs the sporidia obtuse. 



137. S. (Valsa) Kunzei, Fr. S. M. ii. p. 388. Tab. XLVIII. fig. 133, ascus with sporidia, 

 and free sporidia, x 325. Sporidia biseriate, bro\\Tiisli yellow in the mass, almost 

 colourless when single, curved, 0-0004 inch long. Described from a specimen of 

 Mr. Berkeley's, that at Kew having no fruit. 



138. S. (Valsa) concamerata, n. s. Tab. XLVIII. fig. 134, ascus with sporidia, x 325. 

 Sporidia crowded, colourless, curved, 0-0004 inch long ; perithecia raising the inner 

 bark into a dome-shaped conceptaculum, nests of perithecia united by white wooUy 

 fibres. On oak ; qucere, a form of S. ceratosperma ? 



139. S. cincta, n. s. Tab. XLVIII. fig. 185, ascus with sporidia, x 325. Sporidia unise- 

 riate, dark rich browTi, obtuse, constricted in the middle, 0-0007 inch long, uniseptate ; 

 perithecia irregularly ovate, closely packed in a compact leathery couceptaculiuu ; 

 ostiola bursting thi'ough the bark and forming round dark pustules : imder a lens the 

 ostiola seem surroimded with a dii-ty-olive-green stroma. Blackheath Park, Slarch 

 1865. 



140. S. (Valsa) Sorbi, Schmidt ; Fr. S. M. ii. p. 380. Sporidia not distinguishable from 

 those of S. stigma.
