MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPHÆRLÆ. 263 
The asci produce colourless jointed sporidia, which divide at the joints. The latter 
are rod-shaped or cylindrical, 0*0003 inch long, and are shown separately at 5, a, 
being an ascus with its contained sporidia.

an ascus X 225, b and c joints of the filaments more highly magnifled. The asci 
produce jointed sporidia, which divide at the joints, each joint measuring about 0°0001 
inch inlength. Ifind them cylindrical, not oval or elliptical as figured by Robin and 
Berkeley. When free they often appear quite circular (see fig. 7 c), and to consist 
of an outer membrane and a very highly refractive nucleus. This circular appearance 
may arise from a change in the line of sight, although I think it probable that the 
joints, when freed from their mutual pressure, may assume a globular form. 
7. S. (XYLARIA) INVOLUTA, Kl. Tas. XLV. fig. 8, ascus with sporidia, x 325. Sporidia 
uniseriate, dark brown, elliptical or sub-reniform, 0:0007 inch long. The surface of 
this plant, when dry, breaks away from the flesh like a shell, carrying the perithecia 
with it, and the same thing occurs in S. Guianensis, post.

inch long.

militaris, &c. "The joints are rod-shaped or cylindrical, 0-0006 to 00008 inch long. 
S. (Hyroxyton) Canopus, Mont. Ta». 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 Montagne's collection. I doubt if it is distinct from S. deusta, 
Hoff. It should, I think, be arranged in the Glebosæ. 
S. (XYLARIA) POLYMORPHA, Pers. Fr. S. M. p. 326. Tas. XLV. fig. 17, ascus with 
sporidia, and a free sporidium, x 325.  Sporidia uniseriate, dark reddish brown, 
curved slightly, 0:0003 to 0:0004 inch long. 
S. (Hxroxvrow or Ponox1A) HELISCUS, Mont. Syll. p. 209. Ta». XLV. fig. 13, spori- 
dia, x 325. Sporidia uniseriate, I think (but there were no complete asci), dark brown, 
irregularly almond-shaped or pyriform, 0:0003 to 00004 inch long. This plant was 
described by Montagne in Cent. ii. No. 44. t. 10. f. 5, under Hypoæylon; but in the 
‘S ' it is transferred to Poronia.
