MR. F. CUllREY ON THE FRUCTIFICATION OF COMPOUND SPH^RI^. 269 



63. S. (DiATRYPE) PLATYSTOMA, Scliwcin. ; Fr. S. M. ii. p. 351. Tab. XLVI. fig. 66, spo- 

 ridia, x about 450. Sporidia colom-less or with a slight yellow tinge, less curved 

 and rather smaller than in SphcBvia stigma ; about 0*0003 inch long. The plant is 

 distinguisliable from S. stigma by its rimose stroma, and by its larger, more protru- 

 ding Pezizyc-form ostiola. 



64. S. (IIypoxylon) vogesiaca, Pcrs. in Litt. Tab. XLVI. figs. 67 and 68, sporidia, X 

 325. Sporidia uniseriate (I believe), at fii'st pale brown, eventually almost opaque 

 with granides and nuclei, elliptical, hut rather irregular, sometimes almost pyriform, 

 0'0007 to O'OOOS inch long. " Ad truncos emortuos Aceris pseudo-platanl ; affinis 

 Sphcerice serpent is sed dist'mcta," is the note attached. 



65. S. (Hypoxylon) vikgultorum, Er. S. M. ii. p. 351, El. xi. 71. Tab. XLVI. fig. 69, 

 sporidia, x 450. Sporidia sometimes uniseriate, sometimes biseriate, lageniform, 

 colourless, or mth an almost imperceptible yellowish tinge, 0'0004 inch long. 



66. S. (Diatrype) atro-punctata, Schwein. ; Pr. S. M. ii. p. 351. Tab. XLVI. fig. 70, 

 ascus with sporidia and free sporidia, X 325. Sporidia uniseriate, overlapping, brown, 

 Avith granular nucleate contents, broadly aluiond-shaped, 0-0010 to 0'0012 inch long. 

 Easily known by the small punctiform ostiola penetrating the white upper siu'face 

 of the stroma. 



67. S. (DiatryteP) rhois, Schwein. ; Fr. S. M. ii. p. 356. Tab. 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 Sphceria verrucceformis ; 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 h from 

 O'OOIO to 0*0014 inch, measured on the chord of the arc. 



68. S. (Dlvtrype) liriodendri, Schwein. ; Fr. S. M. ii. p. 356. Tab. XLVI. fig. 72, asci 

 with sporidia and free sporidia, x 325. Sporidia very crowded, quite filling the asci, 

 brown, just Uke the sporidia of SphcBria favacea and S. aspera, 0*0002 inch long, or 

 rather more. Possibly the plant is only a state of Diatrype aspera. 



69. S. (Diatrype) capxodes, Berkeley. Tab. XLVI. fig. 73, ascus with sporidia and free 

 sporidia X 325. Sporidia uniseriate, at first a clear brown, ultimately quite opaque, 

 uniseriate, elliptical, 0*0004 to 0*0005 inch long. This species is allied to Sphceria 

 stigma ; but the stroma is of a blackish grey colom", and the ostiola more prominent. 

 The fruit, as will be seen, is totally different from that of S. stigma. 



70. S. (Hypoxylon) melanaspis, Mont. Sylloge, p. 215. Tab. XLVI. fig. 74, ascus with 



sporidia and free sporidia, x 325. Sporidia uniseriate, overlapping at the ends, 

 almost colourless, but with a fauit tinge of yellow or rather straw colour, fusiform, 

 but wider at one end than at the other, 0*001 inch long. Forming round black stains, 

 with the ostiola slightly protruding in the middle of the stain. 



71. S. (Diatrype) dryophila, n. s. Tab. XLVI. fig. 75, asci with sporidia and free spo- 

 ridia, X 325. Sporidia uniseriate, narrowly elliptical, subaciuninatc at each end, at 

 first of a pale greenish brown, then darker, and eventually almost black, when young 

 Avith two or more nuclei in each sporidium, 0*0004 to 0*0005 inch long. Perithecia 

 ovate or sub-globose surrounded by a dirty green stroma, rather deeply buried,
