Diaporthe ophites, Sacc. Syll. No. 2595. 
Stroma broadly effused in the bark and the surface of the wood, 
forming variable brown and black spots, limited internally by a 
black line. Perithecia gregarious, globose, of medium size, im- 
bedded in the bark (rarely in the wood). Ostiola filiform, about as 
long as the diameter of the perithecium. Asci fusiform. Sporidia 
biseriate, shortly fusiform, uniseptate, slightly constricted, quadri - 
nucleate, rather obtuse at each end, hyaline (‘012--013 X •0045-*005 
mm.). 
On dead twigs of Hibiscus syriacus. Kew, March, 1885. 
Mixed with Phoma ophites , Sacc. 
Sphaeria (Physalospora) rosicola, Fckl. Sacc. Syll. 1662. 
Perithecia gregarious, covered by the shining blackened cuticle, 
minute, globose, black, with a white nucleus, ostiola somewhat 
prominent, papillate, perforated. Asci fasciculate, oblong-ovate 
(sub-cylindrical ?) eight spored. Sporidia obovate oblong, narrower 
at one end, simple, granular, hyaline (-018 x *009 mm.). 
On Rosa canina. Kew, April, 1885. 
Probably this species, but in the absence of any knowledge of the 
size of the sporidia in Fuckel’s specimens, it must be uncertain. 
Sphaerella (Lsestadia) rhodorae, Cooke. 
Epipbyllous. Perithecia gregarious, seated upon large irregular 
ferruginous spots, immersed in the parenchyma, subglobose, black, 
piercing the cuticle with the punctiform ostiola. Asci clavate, 
without paraphyses (*80-*120 x *16). Sporidia elliptical, hyaline, 
continuous (perhaps *015 X ‘007 mm., but too immature to 
measure with certainty). 
On living leaves of Rhododendron. Kew. 
This can scarcely be the Lcestadia rhododendri , D.Not, of 
Saccardo’s Sylloge. 
Sphaerella (Laestadia) Iridis, Cke. 
Caulicolous. Perithecia loosely gregarious for some inches, 
punctiform, covered by the cuticle, which is pierced by the minute 
ostiolum. Asci clavate sessile, octosporous. Sporidia elliptical, 
slightly attenuated towards each extremity (*012--014 x , 004- , 005 
mm.) hyaline. 
On flower stalks of Iris germanica. Kew Gardens, March. 
Floeospora herbarum, var. Iridis. 
Sporidia 7 septate, muriform, bright amber colour, *04 x '016 mm. 
On flower stalks of Iris germanica. Kew Gardens. 
In company with Sphcerella ( Lcestadia ) Iridis. 
lilieptosphaeria (XVIetasphaeria) acorella, Cooke. 
Scattered, epiphvllous. Perithecia minute, subglobose, at first 
covered, then erumpent, and the upper portion exposed, slightly 
papillate, black. Asci clavate, eight-spored. Sporidia fusiform, 
biseriate, five septate, constricted a little at the central septum, at 
first nucleate, hyaline -OS-’OSb x , 006 mm. 
On leaves of Acorus calamus — mixed with Phoma acori, 
Totteridge. Kew.
