The asci produce colourless jointed sporidia, wliich divide at the joints. The latter 

 are rod-shaped or cylincU'ical, O'OOOS inch long, and are shown separately at b, a, 

 being an ascus with its contained sporidia. 



6. S. (CoRDYCEPs) OPHiOGLOssoiDES, Ehrh. ; Fr. S. M. ii. p. 324. Tab. XLV. fig. 7 «, 



an ascus X 225, b and c joints of the filaments more highly magnified. The asci 

 produce jointed sporidia, which divide at the joints, each joint measuring about O'OOOl 

 inch in length. I find them cylindrical, not oval or elliptical as figui-ed by Robin and 

 Berkeley. When Tree they often appear quite cu-cular (see fig. 7 c), and to consist 

 of an outer membrane and a very highly refractive nucleus. This cu-cular appearance 

 may arise fi-om a change in the line of sight, although I think it probable that the 

 joints, when freed from their mutual pressure, may assume a globulai" form. 



7. S. (Xylaria) involuta, K1. Tab. XLV. fig. 8, ascus with sporidia, x 325. Sporidia 



uniseriate, dark brown, elliptical or sub-reniform, 0-0007 inch long. The sui-face of 

 this plant, when dry, breaks away from the flesh like a shell, carrying the perithecia 

 with it, and the same thing occnrs in (S*. Guianensis, post. 



8. S. (Xylaria) Guianensis, Mont. Syll. p. 202. Tab. XLV. fig. 9, ascus and sporidia, 



X 325. Sporidia uniseriate, brown, rather dark, elliptical or slightly curved, 0'0006 

 inch long. 



9. S. (CoRDYCEPs) CAPITATA, HoLmsk. Tr. S. M. p. 324. Tab. XLV. fig. 10 a, ascus with 



sporidia; b, free joints, x 225. The asci produce jointed colourless sporidia, as in S. 

 militaris, &c. The joints are rod-shaped or cylindrical, 0-0006 to 0-0008 inch long. 



10. S. (Hypoxylon) Ccenopus, Mont. Tab. XLV. fig. 11, sporidia, X 325, sporidia clear 

 brown, curved, elliptical or plano-convex, 0-001 inch long. This plant is from Guiana, 

 from Leprieur and Montague's collection. I doubt if it is distinct from >S'. deusta, 

 Hoff. It should, I think, be arranged in the Glebosse. 



11. S. (Xylaria) polymorpha, Pers. Pr. S. M. p. 326. Tab. XLV. fig. 17, ascus with 

 sporidia, and a free sporidium, x 325. Sporidia uniseriate, dark reddish brown, 

 curved slightly, 00003 to 0-0004 inch long. 



12. S. (Hypoxylon or Poronia) heliscus, Mont. SyU. p. 209. Tab. XLV. fig. 13, spori- 

 dia, X 325. Sporidia uniseriate, I think (but there were no complete asci), darkbromi, 

 irregularly almond-shaped or pyriform, 00003 to 00004 inch long. This plant was 

 described by Montague in Cent. ii. No. 44. t. 10. f. 5, under Hypoxrjlon ; but in the 

 ' SyUoge ' it is transferred to Poj'onia. 



13. S. RHOPALorDES, Mont. Tab. XLV. fig. 14, ascus with sporidia, x 325. Sporidia 

 uniseriate, dark (rather reddish) brown, elliptical, but irregular in shape, 0-0003 

 inch long. Hypoxylon, Pr. 



14. S^ (Hypoxylon) crenulata, Berkel. Tab. XLV. fig. 15, sporidia, x 325. Sporidia 

 biseriate, greenish, slightly ciuwed, endochrome usually divided into four portions, 

 giving a triseptate appearance, 0-0007 to 0-001 inch long. Sporidia occasionally 

 uniseriate and overlapping, endochrome sometimes divided into 3 portions only. 



15. S. (Xylarls.) digitata, Pers. Pr. S. M. p. 320. Tab. XLV. fig. 16, ascus with sporidia, 



X 325. Sporidia uniseriate, dark brown, curved, 00007 inch long. "When imi-ipe, 

 transparent mth one or two nuclei.
