322 MR. F. CURREY ON THE FRUCTIFICATION OF SIMPLE SPHjERI^. 



Sporidia biseriate (? sometimes uniseriate), yellow at first, eventually brown, 5- 

 septate, rarely with 6 or more septa, frequently with longitudinal divisions, rendering 

 the sporidia multicellular, O'OOIO to 0'0012 inch long. I have a plant from Mr. 

 Bloxam marked S. macrostoma, Tode, the fruit of which is drawn in fig. 65, X 220 

 diameters. These sporidia attain a length of from 0'0020 to 00026 inch. 

 284.. S. LiGNiARiA, Grev. Sc. Cr. Fl. t. 82. Tab. LVIII. fig. 66, ascus with sporidia, 

 X 425. Sporidia uniseriate, at first pale brown, then dark brown, elliptico-acuminate, 

 O'OOOS inch long. Perithecia somewhat flask-shaped, with a rugose, or rather velvety 

 appearance, but not at all shining. 



285. S. CRiSTATA, Pers. = ,S'. crenata, Er. S.M. ii. 469. Tab. LVIII. fig. 67, sporidia, x 325. 

 Sporidia almond-shaped, brown, 5-7-septate, 0-0016 to O'OOIB inch long. Quaere if 

 distinct from S. macrostoma, Tode.

286. S. BREViEOSTRis, Fr. S. M. ii. 474. Tab. LVIII. fig. 68, ascus with sporidia, x 325. 

 Sporidia biseriate or uniseriate, pale brown, 0-0006 to 0-0007 inch long, eUiptical, 

 rather pointed at the ends. 



287. S. LONGISPORA, n. s. Tab. LVIII. fig. 69, ascus with sporidia and free sporidia, 

 («) x 325, {b) X 425. Sporidia filiform, arranged side by side, very variable in length 

 and in the number of septa, yellowish brown. Perithecia flattened, with a short 

 ostiolum, mostly covered by the bark, excepting the tip of the ostiolum. This plant 

 is marked in the herbarium " S. rostellata," but it differs from that species in the 

 ostiolum. 



288. S. (Cytispora) micxtla, Fr. El. ii. 101. Tab. LVIII. fig. 70, fruit, x 325. No asci ; 

 stylospores variable in length, colourless, fusiform, very pointed; ostiola fuscous. 

 An imperfect state of some SphcBria. 



289. S. (Sph^eropsis ?) pilifera, Fr. S. M. ii. 472. Not ascigerous, the perithecia pro- 

 ducing only a mass of minute colourless spermatia. Remarkable for its beautifully 

 fine, hair-like ostiolum. Perithecia small and globose. 



290. S. ciRRHOSA, MS. Tab. LVIII. fig. 71, ascus with sporidia, X 425. Sporidia bi- 

 seriate, elliptical, colourless, 0-0004 to 0-0005 inch long. Perithecia ovate or turbi- 

 nate, quite buried in the wood, but piercing the surface by their very long, almost 

 filiform ostiola. There is another plant marked aS*. cirrhosa, the fruit of which is 

 shown in fig. 72, x 325 diameters. Here the sporidia are uniseriate or biseriate, pale 

 greenish brown, eUiptical, frequently with one, two, or more nuclei, 0-0003 to 

 0-0004 inch long. Perithecia subovate, ostiola about as long as the perithecia. 



291. S. ROSTRATA, Fr. S. M. ii. 473. Sporidia biseriate, elliptical or slightly curved, 

 0-0003 to 0-0004 inch long, colourless, or with a tendency to pale brown. Probably 

 not distinct from S. cirrhosa, supra.
