330 MR. F. CURREY ON THE FRUCTIFICATION OF SIMPLE SPHvERIiE. 



350. S. Dematium, Pers. ; Fr. S. M. ii. 605. Tab. LIX. fig. 123, sporidia, x 325. This 

 plant was not, I think, quite ripe. Most of the sporidia were curved and colourless, 

 as in the right-hand one of the three ; hut septa were just visible in one or two of 

 the sporidia, and nuclei in others. I have little doubt that the sporidia, when ripe, 

 are brown or yellowish, and three or four times (or even more) septate. There are 

 three specimens of this species in the herbariimi, marked a, (3, and y. The above de- 

 scription is from (a) ; I could find no fruit in ()3) and (■/). 



351. S. Arundinis, Pr. S. M. ii. 510. Tab. LIX. fig. 124, sporidia, X 425. Sporidia bi- 

 seriate, at first yellowish, then brown, 3-5-septate, sometimes with six septa, slightly 

 curved, somewhat pointed at each end, frequently with nuclei in the septa, O'OOIO to 

 0-0016 inch long. 



352. S. (Sph^ropsis ?) Corni Suecic^. Not a true Sphceria. Perithecia producing only 

 minute, straight, cylindrical, coloiu-less spermatia, 00002 inch long. 



353. S. (Sph^eropsis ?) acuta, Hofi'm. I believe aS*. acuta, Hoflfm., to be only a sphserop- 

 soid state of some common Caulicolous species; but whether of S. complanata or 

 S. herbarum, or of any other species, it is impossible to say. 



354. S. COMPLANATA, Todc. It is difiicult, without authentic specimens, to be certain as 

 to the true S. complanata of Tode. The sporidia shown in Tab. LIX. fig. 125, x 325 

 diameters, are those which I have always supposed to belong to the true species. 

 These sporidia are biseriate, or uniseriate and overlapping, colourless, or yellow, 

 274-partite, sometimes apparently triseptate ; they vary at different ages of the 

 plant ; (a) represents the young state, {b) the more advanced ; (c) is a form equally 

 common (in the same specimens) with (6) ; {d) is, I think, the perfect and typical 

 form of fruit. 



355. S. coxiEORMis, Fr. S. M. ii. 508. Tab. LIX. fig. 126, sporidia, x 325. Sporidia bi- 

 seriate, yellow, sUghtly curved, 5-11-partite, varying much in length, as is shown by 

 the figure. See the remarks on the fruit of this species as compared with S. acumi- 

 nata. Sow., in Ann. and Mag. Nat. Hist. ser. 2. vol. ix. p. 328. 



356. S. imbebbis, MS. This specimen contains three different plants — 1st, Sphceria 

 herbarum ; 2ndly, perithecia containing curved colourless stylospores, like the sper- 

 matia of S. verrucceformis ; Srdly, perithecia containing minute, colourless, straight, 

 or slightly curved cylindrical spermatia or stylospores. 



357. S. PH/EOSTicTA, Berk. Tab. LIX. fig. 127, ascus with sporidia and free sporidia, 

 X 325. Sporidia uniseriate or biseriate, very dark brown, subcymbiform, 0*0004 

 inch long. Perithecia minute, punctLform. On Sierochloe Brunoms, from the Auck- 

 land Group and Campbell Islands. 



358. S. (Hendersonia) Ze^, Schwem. ; Fr. S. M. ii. 527. Tab. LIX. fig. 128, fruit, 

 X 325. No asci. Perithecia containing the narrowly cylindrical or irregularly- 

 shaped bodies shown in fig. 128. These bodies have a bipartite endochrome, and are 

 rather dark brown. On culms of Zea Mays. If there be no asci, this plant is a 

 Hendersonia ; but the asci may have dissolved, and then it would be a Sphceria. 

 There is another specimen in the herbarium marked S. Zece, Sz., which is, I think, 

 identical with Hendersonia arena, B. & Br.
