MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPHJERLE. 9265 
from that of S. purpurea, except that the hyaline knob at the apex of the aseus is 
very distinct in each ascus; one ascus which I measured was 0-002 inch, another 
0:0034 inch long; so that their length is very variable. The sporidia entirely fill the 
ascus, as in S. purpurea, but I think they sometimes, if not always, overlap one 
another, so that their length is not always equal to that of the ascus. 
26. S. (Corpycers) Roszrtsu, Hook. Ta». XLV. fig. 26, ascus with fruit, x 425. 
The fruit here, as in the other true species of Cordyceps, consists of long colourless 
sporidia, which break up into joints. At least, the sporidia are divided by septa 
into a number of small portions, which probably separate from one another at 
the partitions, as in S. militaris, capitata, &c. The septa are sometimes very 
indistinct. 
26a. S. (CORDYCEPS) TYPHINA, Pers. Fr. S. M. ii. p. 553, under Dothidea. The fructifi- 
cation is almost identical with S. militaris, although the asci are smaller.

27. 8. (PORONIA) PUNCTATA, Sow. Tas. XLV. fig. 27, ascus with sporidia, x 825. Spo- 
ridia uniseriate, brown when young, and then slightly granular, quite black and 
opaque when ripe, elliptical, varying in length from 0-0008 to 0:0012 inch.

28. S. (HYPOXYLON) MULTIFORMIS, Fr.! S. M. ii. p. 334. Ta». XLV. fig. 28, ascus with 
sporidia, x 450. Sporidia uniseriate, rich yellowish-brown, elliptical, but usually 
slightly curved, 0:0004 inch long. 
29. S. (HYPOXYLON) DURISSIMA, Sz.; Fr. S. M. ii. p. 335. Ta». XLV. fig. 29, ascus with 
sporidia, x 325.  Sporidia uniseriate, clear dark brown, elliptical, but frequently 
slightly curved, 0:0003 to 0:0004 inch long. This plant is marked with a ?; and it 
seems doubtful whether it is not a form of S. multiformis. The perithecia are blacker 
and rather more dome-shaped than in my specimens of S. multiformis, and they have 
a decided nipple-shaped ostiolum. The sporidia have usually one good-sized nucleus, 
sometimes two, or even more. 
30. S. (HYPOXYLON) FRAGIFORMIS, Pers.; Fr. S. M. ii. p. 332. Ta». XLV. fig. 30, spo- 
ridia, x 325. Sporidia uniseriate?, dark opaque brown, elliptical or areuate, with 
sometimes one or two nuclei visible, but mostly too opaque for the nuclei to be seen; 
0:0006 inch long. |

fig. 31, sporidia, x 450. Sporidia light brown, elliptical, 0°0003 inch long. ^ 
32. S. (HYPOXYLON) CONCENTRICA, Bolt. Fr. S. M. ii. p. 331. Tas. XLV. fig. 32, sporidia, 
x 325. Sporidia uniseriate, dark brown, sometimes with a large elliptical or reni- 
form nucleus, elliptical, but sometimes of irregular shape, 0-0005 inch long. 
33. S. (HYPocREA) GELATINOSA, Tode ; Fr. S. M. ii. p.336. Tas. XLV. fig. 33, ascus with 
sporidia, x 325. Sporidia uniseriate, colourless, squarish in the ascus, more nearly 
round when free, with one or many, or with no nuclei, 0-0002 inch in diameter when 
free. Almost precisely similar in fructification to S. rufa (see post), and like that,
