MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPH^RI^. 279 



150. S. (Valsa) querna, n. s. Tab. XLVIII. fig. lil, ascus with sporidia, x 325. Spo- 

 ridia slightly cui'ved, simple, linear, colourless, siibhyahnc, croAvded at the apex of 

 the ascus as in many Pezizce, 0-0002 to 0-0003 inch long. Weybridge, 1856. Not 

 in a sufficiently good condition to describe the perithecia accurately. The fruit 

 differs from that of any of the allied species with which I am acquainted. 



151. S. (Valsa) biconica, n. s. Weybridge, January 7, 1856. Tab. XLVIII. fig. 142, 

 ascus with sporidia, and free sporidia, x 220. Sporidia biconical ; endochrome gra- 

 nular or oleaginous, greenish ; 0-0011 to 0001 2 inch long ; perithecia globose or 

 depressed, few together, arranged in circles, penetrating the bark with their rather 

 short ostiola and forming small pustules. 



152. S. (Vaisa) pulchra, n. s. Tab. XLVIII. fig. 143, ascus with sporidia, x 225. 

 Sporidia biseriate, elliptical but shghtly constricted m the middle and slightly 

 acuminate at each end, uniseptate, greenish ; perithecia imperfect. 



153. S. (Valsa) suffusa, Fr. S. M. ii. p. 399. Tab. XLVIII. fig. 114, sporidia, x 225. 

 Sporidia variously curved from their great length, colom-less, granular, biseriate or 

 crowded. 



154. S. (Valsa) Juglandis, Schwein., non Fries. Tab. XLVIII. fig. 145, sporidia, X 

 450. Sporidia biseriate, yellowish, as in S. stigma, 0-0003 to 0-0004 inch long. 



155. S. (Valsa) Abietis, Fr. S. M. ii. p. 398. Tab. XLVIII. fig. 147, ascus with sporidia, 

 and free sporidia, x 325. Sporidia biseriate, colourless, curved, 0-0003 to 0-0006 

 inch long. This I believe to be the true S. Abietis of Fries. Fig. 146 represents 

 the fruit of a Sphwria also occurring on Fir and resembling S. Abietis in general 

 appearance. The sporidia in this latter plant are biseriate, colourless, subhyaline, 

 curved, acuminate at each end, 1-septate or pseudo-septate, 0-0007 inch long. It is 

 possilile that the species may not be really different from S. Abietis, and that the 

 latter may, in its perfect state, have septate sporidia. There are, as stated above, 

 several Sphcerice in which the normal state of the fruit is septate, but in which that 

 state is often not attained. 



150. S. (Valsa) tetraspora, n. s. Weybridge, January 1856. Tab. XLVIII. fig. 148, 

 ascus with sporidia, and free sporidia, X 325. Sporidia simple, slightly curved, rounded 

 at each end, colourless, only 4 in each ascus, biseriate, 0-0008 inch long ; perithecia 

 globose ; ostiola surrounding or scattered through a white disk. The plant hardly 

 differs from S. ambient, except in its tetrasporous fructification. 



157. S. (Valsa) salicina, Pers. ; Fr. S. M. ii. p. 401. Tab. XLVIII. fig. 149, ascus with 

 sporicUa, and free sporidia, x 325. Sporidia biseriate, colourless, uniseptate, with gra- 

 nules and small nuclei, the septum often very difficult to make out, elliptical, but 

 usually slightly cm-ved, and often slightly constricted in the middle, 0-0009 inch long. 



158. S. (? Valsa) intexta, n. s. Tab. XLVIII. fig. 169, ascus with sporidia, X 325. 

 Sporidia interwoven, generally nearly as long as the ascus, filiform and flexuous. 

 Tills plant was not in a state to enable me to describe the perithecia. It appears to 

 belong to the Circiuatse, and occm-red on oak at Weybridge. The paraphyses were 

 very long and numerous, and septate. I know of no species to which it can be 

 referred, although the sporidia somewhat resemble those of S. suffusa, Fr.
