MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPHiERIiE. 281 



elliptic, rather irregular, varying much in length, the average being about 0'0008 

 inch. I could find no asci. 



167. S. (Vaisa), ? sp. Tab. XLVIII. fig. 163, ascus with sporidia, x 225. This plant is 

 one of the " Fungi Pyrenai," and is marked " S. coharens, Fers." in that collection. 

 It has, however, no afiinity with S. eoJucrens, but belongs to the Circinatse. The 

 fruit differs from that of all other species of the division CircinatiE mth which I am 

 acquainted. The sporidia are uniseriate, of a rich brown colour, obtusely elliptical, 

 uniseptate, 0"0014< inch long. 



168. S. (Vaxsa) quaternata, Pers. Syn. p. 45. Tab. XLVIII. figs. 164 and 165, asci 

 with sporidia, and tree sporidia. In fig. 164, a is x 220, b about 325 diameters. 

 Fig. 165 is X 450. Sporidia biseriate, almost colourless when separate, but in a mass 

 of duU-brownish yeUow, Uke the colour in S. stigma, S. stellulata, &c., curved, 0-0004 

 to 0-0006 inch long. 



169. S. (Valsa) Innesii, n. s. Tab. XLVIII. fig. 166, sporidia, x 325. SporicUa 

 biseriate, coloui-less, acute at each end, and constricted three times ; endochrome 

 4-partite ; 0-0010 to 0-0012 inch long. Sporidia frequently, if not always, with a 

 delicate appendage at each end. Perithecia irregularly globose ; ostiola elongated and 

 frequently thickened at the apex. Externally much resembling S. pulchella, but 

 smaller and differing altogether in fructification fr-om that species. 



170. S. (Vaxsa) arcuata, n. s. Tab. XLVIII. fig. 167, asci with sporidia, and free spori- 

 dia, X 325. Perithecia globose, arranged ia cii-cles ; ostiola penetrating the bark and 

 forming a dark-coloui-ed, sometimes dirty-white disk. Sporidia biseriate, pale green, 

 4-5-septate, very flexible, sometimes constricted at the articulations, sometimes not, 

 variable in length, somewhat resembling S. qiiercina, Pers. in its sporidia ; but S. 

 quercina belongs to the Versatiles, and this plant to the Circinatfe. 



171. S. (Valsa) faginea, n. s. Eltham Grove, October 1856. T.uj. XLVIII. fig. 168, 

 sporidia, x 420. Sporidia biseriate, colomdess, elliptic-acuminate, but constricted in 

 the middle, and irregular, 0-0005 iach long. Perithecia conical ; ostiola penetrating 

 the bark, normally long and protruding, but mostly broken off ; when the long ostiola 

 are rubbed off, the plant looks just like S. quaternata or S. turgida. On beech.

172. Sph^ria cupularis, Pers. ; Fr. S. M. ii. p. 416. Tab. XLVIII. fig. 170, asci with 

 sporidia, and free sporidia, x 325. Sporidia biseriate, colomdess, cui-ved, 0-0004 inch 

 long, sometimes rather longer. 



173. S. PsEUDO-BOMBARDA, Mont. Sylloge, p. 228. Tab. XLVIII. fig. 171, ascus with 

 sporidia, and free sporidia, x 225. Sjioridia biseriate or crowded, colom-less, u-re- 

 gular, 0-002 inch long. This plant was in a yoimg state ; the spores when ripe are 

 described by Dr. Montague as 6-septate and " olivaceo-fuliginosas." 



174. S. (Nectria) examixans, Berk. T.uj. XLIX. fig. 172, ascus with sporidia, and free 

 sporidia, x 325. Sporidia uniseriate or biseriate, clear dark brown, elliptical, sub- 

 acuminate, 0-0008 inch long. Perithecia forming long black lines. The contents of 

 the sporidia were mostly clear, sometimes multinucleate, and sometimes granular.
