MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPHÆRIÆ. 279 
150. 8. (Y ALSA) QUERNA, n. S. Tas. XLVIII. fig. 141, ascus with sporidia, x 325. Spo- 
ridia slightly curved, simple, linear, colourless, subhyaline, crowded at the apex of 
the ascus as in many Pezize, 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. Ta». XLVIII. fig. 142, 
ascus with sporidia, and free sporidia, x 220.  Sporidia biconical; endochrome gra- 
nular or oleaginous, greenish; 0'0011 to 0:0012 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. (VALSA) PULCHRA, n. s. Tap. XLVIII. fig. 143, ascus with sporidia, x 225. 
Sporidia biseriate, elliptical but slightly constricted in the middle and slightly 
acuminate at each end, uniseptate, greenish ; perithecia imperfect. 
153. S. (Vausa) SUFFUSA, Fr. S. M. ii. p. 399. Ta». XLVIII. fig. 144, sporidia, x 225. 
Sporidia variously curved from their great length, colourless, granular, biseriate or 
crowded. 
154. S. (Varsa) JUGLANDIS, Schwein., non Fries. Tas. XLVIII. fig. 145, sporidia, x 
450. Sporidia biseriate, yellowish, as in S. stigma, 0-0003 to 00004 inch long. 
155. S. (Varsa) ABIets, Fr. S. M. ii. p. 398. Tas. 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 Spheria 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 
possible 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 Sphæriæ in which the normal state of the fruit is septate, but in which that 
state is often not attained. 
156. S. (VALSA) TETRASPORA, n. $s. Weybridge, January 1856. Tas, 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. ambiens, except in its tetrasporous fructification. : 
157. S. (VALSA) SALICINA, Pers.; Fr. S. M. ii. p. 401. TAB. XLVIII. fig. 149, ascus with 
sporidia, and free sporidia, x 325. Sporidia biseriate, colourless, uniseptate, with gra- 
nules and small nuelei, the septum often very difficult to make out, elliptical, but 
usually slightly curved, and often slightly constricted in the middle, 0-0009 inch long. 
158. S. (P VALSA) INTEXTA, n.s. TAB. XLVIII. fig. 169, ascus with sporidia, x 325. 
Sporidia interwoven, generally nearly as long as > ascus, filiform and flexuous. 
This plant was not in a state to enable me to describe the perithecia. It appears to 
belong to the Circinatæ, and occurred 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.
