MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPHÆRLÆ. 269 
63. S. (DIATRYPE) PLATYSTOMA, Schwein.; Fr. S. M. ii. p.351. Tar. XLVI, fig. 66, spo- 
ridia, X about 450.  Sporidia colourless or with a slight yellow tinge, less curved 
and rather smaller than in Sphæria stigma; about 00003 inch long. The plant is 
distinguishable from S. stigma by its rimose stroma, and by its larger, more protru- 
ding Pezizæ-form ostiola. 
64. S. (HYPOXYLON) VOGESIACA, Pers. in Litt. Ta». XLVI. figs. 67 and 68, sporidia, x 
325. Sporidia uniseriate (I believe), at first pale brown, eventually almost opaque 
with granules and nuclei, elliptical, but rather irregular, sometimes almost pyriform, 
0:0007 to 00008 inch long. * Ad truncos emortuos Aceris pseudo-platani ; affinis 
Sphæriæ serpentis sed distincta," is the note attached. 
65. S. (HYPOXYLON) viRGULTORUM, Fr. S. M. ii. p. 351, El. xi. 71. Ta». XLVI. fig. 69, 
sporidia, x 450. Sporidia sometimes uniseriate, sometimes biseriate, lageniform, 
colourless, or with an almost imperceptible yellowish tinge, 0°0004 inch long. 
66. S. (DIATRYPE) ATRO-PUNCTATA, Schwein. ; Fr. S. M. ii. p.951. Tas. XLVI. fig. 70, 
ascus with sporidia and free sporidia, x 325. Sporidia uniseriate, overlapping, brown, 
with granular nucleate contents, broadly almond-shaped, 00010 to 0:0012 inch long. 
Easily known by the small punctiform ostiola penetrating the white upper surface 
` of the stroma. : 
67. S. (DIATRYPE?) raors, Schwein. ; Fr. S. M. ii. p. 356. Ta». XLVI. fig. 71a, sporidia ; 
b, stylospores. The specimens are in bad condition; but one perithecium produced the 
sporidia a, which are yellowish like those of Sphæria verrucæformis ; another produced 
the stylospores or spermatia b, which were colourless and produced on sporophores 
attached to the wall of the perithecium. Length of a about 0:0003 inch, of å from 
0:0010 to 0:0014 inch, measured on the chord of the arc. 
68. S. (DIATRYPE) LIRIODENDRI, Schwein. ; Fr. S. M. ii. p.356. Ta». XLVI. fig. 72, asci 
with sporidia and free sporidia, x 325. Sporidia very crowded, quite filling the asci, 
brown, just like the sporidia of Sphæria favacea and S. aspera, 0:0002 inch long, or 
rather more. Possibly the plant is only a state of Diatrype BPM idis 
69. S. (DIATRYPE) cAPNODEs, Berkeley. Tas. XLVI. fig. 73, ascus with sporidia and free 
sporidia x 325. Sporidia uniseriate, at first a clear brown, ultimately quite opaque, 
uniseriate, elliptical, 00004 to 0:0005 inch long. This species is allied to Sphæria 
stigma; but the stroma is of a blackish grey colour, and the ostiola more prominent. 
The fruit, as will be seen, is totally different from that of S. stigma. 
70. 8. (Hyroxxzon) mELANASPIS, Mont. Sylloge, p. 215. Tas. XLVI. fig. 74, ascus with 
sporidia and free -sporidia, x 325.  Sporidia uniseriate, overlapping at the ends, 
almost colourless, but with a faint tinge of yellow or rather straw colour, fusiform, 
but wider at one end than at the other, 0001 inch long. Forming round black stains, 
with the ostiola slightly protruding in the middle of the stain. amet 
71. S. (DIATRYPE) DRYOPHILA, n.s. Ta». XLVI. fig. 75, asci with sporidia an p 
ridia, x 325. Sporidia uniseriate, narrowly elliptical, subacuminate å - - ae 
first of a pale greenish brown, then darker, and eventually almost black, w så er 
with two or more nuclei in each sporidium, 00004 to 0-0005 inch long. Perithecia 
ovate or sub-globose surrounded by a dirty green stroma, rather pd buried,
