MR. F. CURREY ON THE FRUCTIFICATION OF SIMPLE SPHÆRIÆ. 315 
Polyporus versicolor. I have in my herbarium a Sphæria on Polyporus hispidus, 
not apparently distinct from N. aurantia, Pers., but producing the fruit shown in 
fig. 7, where the sporidia are elliptical, not acuminate or flexuous, 00005 inch long, 
and very different in appearance from those of the Kew plant. 
222. S. THELENA, Fr. S. M. ii. p.441. Ta». LVIL fig. 8, ascus with sporidia, x 825. 
Sporidia uniseriate, black-brown, opaque, elliptical or slightly curved, sometimes 
with a large nucleus, 00009 inch long. Not distinct, I should say, from $8. aquila, 
Fr., although the sporidia are rather narrower. 
223. S. LANATA, Fr. 8. M. ii. p.442. The specimens of this plant are in bad condition. 
I could find very few sporidia, and those hardly differed from the sporidia of S. the- 
lena, except perhaps in being slightly more acuminate. Perithecia somewhat col- 
lapsed, without a manifest ostiolum ; subiculum loose, hairy. 
224. S. SUBICULATA, Sz.; Fr. S. M. ii. p.443. Tas. LVII. fig. 9, sporidia, x 325. Spo- 
ridia broadly elliptical, with sometimes one, sometimes two nuclei; the two occa- 
sionally approaching so close as to give a septate appearance, dark brown, 00004 
inch long. The subiculum is wanting in the Kew specimens. The plant is like 
S. aquila, but the perithecia are blacker, flatter, and much smaller. 
225. S. ALLIGATA, Fr. S. M. ii. p. 445. Tas. LVII. fig. 10, ascus with sporidia, x 325. 
Sporidia uniseriate or biseriate, yellowish, oblong, obtuse or somewhat pointed at 
the ends, constricted in the middle, 0:0007 inch long. Erumpent, but furnished 
with a subieulum ; endochrome bipartite. ae

biseriate, linear, acuminate, usually with four nuclei, but sometimes with only two 
large ones, producing a spurious uniseptate appearance, colourless, 0:0003 to 0.0004 
inch long.
