black pulvinate tubercle, through wliich the densely crowded ostiola penetrate and 

 cause a scabrous appearance ; ostiola somewhat elongated and rounded. Communi- 

 cated by Mr. Bloxam, from Leicestersliire.

 fig. 96, ascus with sporidia, X 450. Sporidia at first colourless or pale green, at 

 last dark brown, uniseriate ; average lengtli a little over 0-0004 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. 



98. S. (Dlvtrtpe) Motjgeotii, 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), 

 ii-regularly oblong, constricted in the middle, multi-septate, with frequently longitu- 

 dinal septa (or rather pseudo-septa; for aU 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 Ccespitosce, but clearly 1)elong- 

 ing to the Versatiles. On di-ied branches of Acer Fseudo-platanus. 



Div. 8. CONCRESCENTES. 



99. S. FIBROSA, Pers. ; Fr. S. M. ii. p. 384. Tab. 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. ; Montague, Sylloge, p. 232. Tab. XLVII. fig. 99, ascus with 

 sporidia, X 325 ; detached sporidia, x 450. Sporidia curved, of a pale yellowisli 

 colour, each ascus containing a great number. Asci -nith theii- sporidia much 

 resembling Sph. favacea ; sporidia 0-0004 inch long. 



101. S. PARALLELA, Fr. S. M. ii. p. 373. Tab. 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. Tab. XLVII. fig. 101, sporidia 

 highly magnified. Sporidia biseriate, cm-ved, of a pale yellowish tinge, just like the 

 colour in S. stigma, 0-0004 inch long. Very like Sph. stigma, only there is no dark- 

 coloiu-ed stroma. 



103. S. FiMETi, Pers., var. equina. Tab. XLVII. fig. 102, ascus with sporidia, and 

 a free sporidium, x 325. Sporidia uniseriate, broadly ovate, sometimes slightly acii- 

 minate, sometimes obtuse at the ends, of a deep broivn colour, or almost black, quite 

 opaque when ripe, 0-0008 inch long. When immatm-e, the sporidia are pale brown, 

 with large nuclei. 



104. S. (Diplodia) Diosptri, Schwein. ; Fr. S. M. ii. p. 372. 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. 



105. S. VELATA, Pers. ; Fr. S. M. ii. p. 375. Tab. XLV. fig. 104, ascus with sporidia, 

 X 325, and two free sporidia more highly magnified. Sporidia crowded, quite colour-
