278 MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPHiERI^. 



I'll. S. (Valsa) sacculus, SchAvein. ; Er. S. M. ii. p. 378. In the spliaeropsoid state, 

 spevmatia colourless, delicate, slightly ciu'ved, obtuse or subobtuse at the ends, 

 0-0002 to 0-0003 inch long. 



142. S. ENTEROXANTHA, Berk. Fructification exactly similar to that of S. stigma, as well 

 in the glutinous nature of the contents of the perithecia as in the size, shape, and 

 colour of the asci and sporidia. Prom British Guiana. 



143. S. (Valsa) CuATiEGi, n. s. Tab. XLVIII. fig. 135 a, sporidia, x 423. Sporidia bise- 

 riate, oblong or elliptical, sometimes curved ; endochrome 4-, sometimes 2-partite, 

 colourless, 0-0006 to 0-0010 inch long ; perithecia irregularly globose ; ostiola rather 

 short. Very common on thorn near Blackheath and elsewhere. 



144. S. (Vaisa) dryina, n. s. Tab. XLVIII. fig. 135 b, ascus with sporidia, and free 

 sporidia, X 325. Sporidia biseriate or crowded, colourless, strongly curved ; both asci 

 and sporidia very delicate and hyaline ; 0-0003 inch long. On dead oak-branches at 

 Weybridge. Perithecia pyriform, imbedded in a dirty-brown stroma ; ostiola rather 

 shorter than the body of the perithecia, and somewhat thickened towards the apex. 



Div. 11. Obvallat^. 



145. S. (Valsa) coronata, Hoffm. ; Fr. S. M. ii. p. 396. Tab. XLVIII. fig. 136, ascus with 

 sporidia, X 325. Sporidia coloiu-less, biseriate, eUiptic-acumiuate, constricted in 

 the middle, 0-0007 to 0-0008 inch long. 



146. S. (VAiSA) leiphyEMIA, Pr. Syst. Myc. ii. p. 399. Tab. XLVIII. fig. 137, sporidia, 

 X 450. Sporidia biseriate, colourless or pale green, elongate-acuminate, slightly 

 curved ; endochrome refractive or granular, consisting of two distinct portions with a 

 clear space (not, I think, a. septum) between them ; the outer membrane is so deMcate 

 that it is frequently not visible. I have found specimens in which the sporidia have 

 oozed out of the perithecia and formed round rose-coloured tubercles at the apices 

 of the ostiola, looking hke Tubercularia vulgaris (see remarks under S. taleola). 

 Length of sporidia about 0-0007 tach. 



147. S. (Valsa) ambiens, Pers. Syn. p. 44. ; Pr. S. M. ii. p. 403. Tab. XLVIII. figs. 138, 

 138 a, asci with sporidia, and free sporidia, X 325. Sporidia colourless, crowded, 

 cui'ved, rounded at each end, 0-0006 inch long. 



148. S. (Valsa) turgiba, Pers. ; Pr. S. M. ii. p. 400. Tab. XLVIII. fig. 139, ascus 

 with sporidia, and free sporidia, x 325. Sporidia uniseriate, at first a jiale clear 

 greenish brown with two or more nuclei, eventually a very dark opaque brown 

 without (or with hardly visible) nuclei, elliptical, subacuminate, 0-0003 to 0-0004 

 inch long. 



149. S. (Valsa) stilbostoma, Pr. S. M. ii. p. 403. Tab. XLVIII. fig. 140, ascus with 

 sporidia, and free sporidia, X 325. Sporidia biseriate, colourless, acuminate-eUiptic 

 but constricted in the middle ; the endochrome divided into two j^ortions (not, 

 I think, septate), sometimes smooth, glossy, and lughly refractive, sometimes 

 granular ; 0-0007 inch long. The variety Flatanoides (see fig. 140 a) has triseptate 

 or pseudo-triseptate sporidia, wliich are 0-0010 to 0-0011 inch long, and sometimes 

 mucronate.
