MR. F. CURREY ON THE FRUCTIFICATION OF SIMPLE SPHyERIy*. 315 



Polyporus versicolor. I have in my herbarium a Sphceriu on Folyporus 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, 0-0005 inch long, 

 and very different in appearance fr-om those of the Kew plant. 



222. S. THELENA, Fr. S. M. ii. p. 441. Tab. LVII. fig. 8, ascus with sporidia, x 325. 

 Sporidia uniseriate, black-brown, opaque, elliptical or slightly curved, sometimes 

 with a large nucleus, 0*0009 inch long. Not distinct, I should say, from S. aquila, 

 Fr., although the sporidia are rather narrower. 



223. S. LANATA, Fr. S. M. ii. p. 442. The specimens of this plant are ia 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. 448. Tab. 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, 0*0004 

 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. Tab. LVII. fig. 10, ascus with sporidia, x 325. 

 Sporidia uniseriate or biseriate, yellowish, oblong, obtuse or somcAvhat pointed at 

 the ends, constricted in the middle, 0-0007 inch long. Erumpent, but furnished 

 with a subiculum ; endochrome bipartite. 



226. S. TRiSTis, Tode ; Fr. S. M. ii. p.444. Tab. LVII. fig. 11, sporidia, x 450. Sporidia 

 biseriate, linear, acuminate, usually Avith foiu- nuclei, but sometimes with only two 

 large ones, producing a spurious uniseptate appearance, colourless, 0-0003 to 0-0004 

 inch long. 



227. S. PHJEOSTROMA, D. R. and M. ; Fl. Alg. t. xxvi. f. 2. Tab. LVII. fig. 12, sporidia, 

 X 450. Sporidia triseptate, colom'less, or almost so, at each end, clear brown in the 

 middle, with or without nuclei, 0-0014 to 00016 inch long. This plant is the 

 S. tristis /3 of the ' English Flora.'

228. S. SCABRA, n. s. Tab. LVII. fig. 13, sporidia, X 325. Sporidia biseriate, fusiform, 

 constricted in the middle, with many (usually 6) nuclei, colourless, 0-0012 to 0-0014 

 inch long. Perithecia very hairy, seated on a dense subiculum, erumpent. On 

 furze, Weybridge, Oct. 1857. The fr-uit is like that of S. macrotricha, B. and Br. 



229. S. canescens, Pers. ; Fr. S. M. ii. p. 448. Tab. LVII. fig. 14, sporidia, x 450. 

 Sporidia colourless, straight or em'ved, subacuminate, sometimes more pointed at one 

 end than at the other, 00011 to 0-0014 inch long. See observations on the next 

 plant. 



230. S. Racodium, Pers. ; Fr. S. M. ii. p. 449. Tab. LVII. fig. 15, sporidia, x 220. 

 Sporidia biseriate, in the early state (as in the right-hand sporidivmi) not distin- 

 guishable from the fruit of S. hirsuta, eventually pale brown, and 7-scptate, 0002
