MR. F. CURREY ON THE FRUCTIFICATION OF COMPOUND SPHJERLE. 273 
black pulvinate tubercle, through which the densely crowded ostiola penetrate and 
cause a scabrous appearance; ostiola somewhat elongated and rounded. Communi- 
cated by Mr. Bloxam, from Leicestershire.

fig. 96, ascus with sporidia, x 450. Sporidia at first colourless or pale green, at 
last dark brown, uniseriate; average length a little over 00004 inch. The sporidia 
have one, two, or three nuclei, and sometimes the nuclei are so close as to give a 
septate appearance to the sporidium; but I do not think there is ever any real 
septum. i 
98. S. (DrATRvPE) Movexortt, Pers. in litt. Tab. XLVII. fig. 97, ascus with sporidia, 
x 325. Sporidia biseriate, yellow (the same colour as in S. herbarum and S. siparia), 
irregularly oblong, constricted in the middle, multi-septate, with frequently longitu- 
dinal septa (or rather pseudo-septa; for all the septa are, I think, only apparent, 
arising from divisions of the endochrome), 0:0012 inch long. Perithecia with deci- 
duous (?) ostiola. Arranged in the herbarium with the Cespitose, but clearly belong- 
ing to the Versatiles. On dried branches of Acer Pseudo-platanus.

99. S. FIBROSA, Pers.; Fr. S. M. ii. p. 384. Tas. XLVII. fig. 98, ascus with sporidia, x 
420. Sporidia uniseriate, obtusely elliptical, but slightly constricted in the middle, 
colourless; endochrome bipartite, 0-0005 inch long. 
100. S. DEPRESSA, Fr.; Montagne, Sylloge, p. 232. Ta». XLVII. fig. 99, ascus with 
sporidia, x 325; detached sporidia, x 450. Sporidia curved, of a pale yellowish 
colour, each ascus containing a great number. Asci with their sporidia much 
resembling SpA. favacea; sporidia 00004 inch long. 
101. S. PARALLELA, Fr. S. M. ii. p. 373. Tas. XLVII. fig. 100, sporidia highly magni- 
fied. Sporidia pale clear brown, straight or slightly curved, rounded at each end, 
0:0004 to 0:0005 inch long. | | 
102. S. (DiATRYPE) LEIOPLACA, Fr. S. M. ii. p. 370. Tas. XLVII. fig. 101, sporidia 
highly magnified. Sporidia biseriate, curved, of a pale yellowish tinge, just like the 
colour in S. stigma, 0:0004 inch long. Very like Sp. stigma, only there is no dark- 
coloured stroma. | | er 
103. S. FIMETI, Pers, var. EQUINA. Ta». XLVII. fig. 102, ascus with sporidia, and 
a free sporidium, x 325. Sporidia uniseriate, broadly ovate, sometimes slightly acu- 
minate, sometimes obtuse at the ends, of a deep brown colour, or almost black, quite 
opaque when ripe, 0:0008 inch long. When immature, the sporidia are pale brown, 
with large nuclei. ie : 
104. S. (DreLop1a) DrosPvnr, Schwein.; Fr. 8. M. ii. p. 872. This specimen is not in 
good condition. I could find no asci, and am doubtful whether or not the sporidia 
are produced on sterigmata as in Diplodia. The sporidia are dark brown, unisep- 
tate, obtuse, slightly constricted in the middle, 0:0006 to 0-0007 inch long. åå
