NEW OR NOTEWORTHY FUNGI 51 



bursting through the epidermis, which is sometimes torn into 

 laciniaB, black, ovate, opening by a pore which soon becomes very 

 wide and irregular. Sporules oblong-elliptic, obtuse at both ends, 

 usually faintly biguttulate, 9-10 x 3i /x. 



On fallen dry leaves of Primus Lauro-cerasus, Over Whitacre 

 (Wk.), April. 



196. Phoma deusta Fckl. Sacc. Syll. Fung. iii. 155. 

 Pycnidia minute, scattered, black, depressed, each surrounded 



by a mass of brown hyphse which impart a scorched appearance 

 to the spot ; ostiole short ; sporules straight, oblong, continuous, 

 with a minute guttula at each end, 6 x 1^, hyaline. 



On dry bracts, capsules, and peduncles of Bhinanthus Crista- 

 galli, Henley-in-Arden (Wk.), February. The spores were few 

 and imperfect ; some of the pycnidia contained fasciculate groups 

 of what were evidently immature asci, but repeated searches failed 

 to find any ascospores. In Wyre Forest (Ws.), September, I 

 found what was almost certainly a state of the same species, on 

 the same habitat, but this form was identical with Zythia 

 rhinanthi (Lib.), Sacc. Syll. Fung. iii. 615 ; Saccardo quotes 

 Sphceroneina rhinanthi Lib. under both. In this case also the 

 pycnidia were minutely parenchymatous, and dark brown under 

 the microscope ; it was evidently not a Zythia, but a Phoma, but 

 the contents of the pycnidia showed no mature spores.

MINOR 7n. 



Pycnidiis ut in typo ; sporulis valde variis, aliis ovatis con- 

 tinuis uniguttulatis, aliis oblongis 1-septatis fuscis 16-17 x 7-8 /x, 

 muco obvolutis. 



The sporules were in all stages of growth ; some were ovate 

 and continuous, others were distinctly uniseptate. Some had one 

 large guttula, others were darker and biguttulate ; the smallest 

 ones had no guttula. Also they varied in colour from nearly 

 colourless to fuscous olive ; the smaller they were the paler ; the 

 septate ones were the largest, e. g. : — 



Bound or oval spores, nearly colourless 6 fx 



Oval, pale brown, granular . . . 11 x 5 /x 



Ovate, uniguttulate, darker . . . 13 x 8 /* 



Oblong-ovate, biguttulate, darker still . 13 x 9 /x 



Oblong-ellipsoid, uniseptate, fuscous . 16 x 8 /x 



But they varied so much that any length could be found from 



6 to 17 /x, combined with almost any width from 5 to 9 or 10 /x. 



The mass of sporules was involved in a granular viscid globule, 



which dissolved slowly in water. 



On half-dead Box-leaves, Sutton Coldfield, January. The type 

 specimens were on dead leaves of Box. 



198. DiPLODiNA GRAMiNEA Sacc. Syll. Fung. iii. 413. 



Pycnidia ovate-depressed or oblong, often 2 or 3 in a longi- 

 tudinal series, black, formed beneath the cuticle, which is elevated 

 and pierced by the ostiole, and finally in the compound groups is 

 rimose. Sporules elliptic-oblong or subcylindrical, obtuse at both
