278 MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPHÆRLÆ. 
141. S. (Varsa) SACCULUS, Schwein.; Fr. S. M. ii. p.378. In the sphæropsoid state, 
spermatia colourless, delicate, slightly curved, 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. From British Guiana. 
143. S. (Varsa) Crarzer, n.s. Tas. XLVIII. fig. 135 a, sporidia, x 425. Sporidia bise- 
riate, oblong or elliptical, sometimes curved; endochrome 4-, sometimes 2-partite, 
colourless, 00006 to 0:0010 inch long; perithecia irregularly globose; ostiola rather 
short. Very common on thorn near Blackheath and elsewhere. 
144. S. (VALSA) DRYINA, n.s. Ta». XLVIII. fig. 1355, ascus with sporidia, and free 
sporidia, X325. Sporidia biseriate or crowded, colourless, strongly curved ; both asei 
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.

145. S. (Varsa) coronama, Hoffm. ; Fr. S. M. ii. p.395. Tas. XLVIII. fig. 136, ascus with 
sporidia, x 325. Sporidia colourless, biseriate, elliptic-acuminate, constricted in 
the middle, 0:0007 to 0-0008 inch long. 
146. S. (Varsa) LEIPILEMIA, Fr. Syst. Myc. ii. p. 399. Tas. 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 delicate 
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 like Tubercularia vulgaris (see remarks under S. taleola). 
Length of sporidia about 0:0007 inch. | 
147. 8. (Varsa) AMBIENS, Pers. Syn. p.44. ; Fr. S. M. ii p.403. Ta». XLVIII. figs. 188, 
138 a, asci with sporidia, and free sporidia, x 325. Sporidia colourless, crowded, 
curved, rounded at each end, 00006 inch long. 
148. 8. (Varsa) TURGIDA, Pers.; Fr. $. M. ii p. 400. Tas. XLVIII. fig. 139, ascus 
with sporidia, and free sporidia, x 325. Sporidia uniseriate, at first a pale clear 
greenish brown with two or more nuclei, eventually a very dark opaque brown 
without (or with hardly visible) nuclei, elliptical, subacuminate, 00003 to 0:0004 
inch long. 
149. S. (Varsa) srILBOSTOMA, Fr. S. M. ii. p.403. Tap. XLVIII. fig. 140, ascus with 
sporidia, and free sporidia, x 325. Sporidia biseriate, colourless, acuminate-elliptic 
but constricted in the middle; the endochrome divided into two portions (not 
I think, septate), sometimes smooth, glossy, and highly refractive, sometimes 
granular; 0-0007 inch long. The variety Platanoides (see fig. 140 a) has triseptate 
or pseudo-triseptate sporidia, which are 0-0010 to 0:0011 inch long, and sometimes 
mucronate. ;
