prominent ostiole. Asci oblong or subclavate 60 x 6-7 /x; sporidia 

 distichous, fusiform, obtuse at each end, uniseptate, d-guttulate, 

 not constricted, subhyaUne, 14-15 x 3 /x. 



On stems of Urtica dioica, Studley Castle, May. The matrix 

 is stained deeply with black round each stroma. 



185. Leptosph^ria rubicunda Eehm, Sacc. Syll. Fung. ii. 

 25 ; Fung. Ital. t. 292. 



Perithecia gregarious, immersed, then erumpent and nearly 

 free, the matrix tinged round them with a wide crimson stain, 

 brownish black, globose, papillate, then collapsed, 150 fi diam. 

 Asci cylindrical-clavate ; sporidia narrowly fusoid, subclavate, 

 3-septate, yellowish, 20 x 2^ /a. 



On stems of Conium maculatum, Studley Castle, November. 



186. Leptosph^ria microscopica Karst. Sacc. Syll. Fung. 

 ii. 59. 



Perithecia arranged in rows, singly or two together, covered 

 by the raised unchanged epidermis, which is pierced by the minute 

 round ostiole, globular or somewhat depressed, smooth, black, 

 under the microscope subtranslucent, parenchymatous, scarcely 

 or not at all papillate, 100-250 ^ diam. ; asci with very short 

 pedicels, broadly oblong-clavate, obtuse at apex, 90 x 15 /x; 

 sporidia subtristichous, pale brown, triseptate, occasionally con- 

 stricted, one or two loculi subinflated, oblong-fusoid, slightly 

 curved, obtuse at each end, 24-28 x 6-7 /a; paraphyses few, 

 slender, linear. 



On culms and sheaths of Dactylis glo7nerata and Phletcm 

 pratense, Studley Castle (Wk.), Selly Oak (Ws.), Baggeridge 

 Colliery (St.), July-December. I have also found, at Packwood 

 (Wk.), a form of this approaching L. vagans Karst., distinguished 

 by its slightly larger perithecia and spores, the latter measuring 

 34-38 X 11 fx. 



187. Metasph^ria culmifida Sacc. Syll. Fung. ii. 174. 

 Perithecia scattered, or two or three together in a row, covered 



by the epidermis which is unchanged in colour, at length splitting 

 it and erumpent, ellipsoid or roundish, flattened at the base, with 

 a short subconical ostiole, black, glabrous, shining ; asci oblong- 

 clavate, fasciculate, very shortly stipitate, 90 x 14 ; sporidia 

 fusiform, straight when seen from the front, curved when seen 

 sideways, 3-septate, not constricted, eguttulate, pale yellowish, 

 distichous, 25-30 x 6-9 /x. 



On culms of Poa, Harborne (Wk.), July. 



188. Pleospora thujae in. Peritheciis sparsis, emergentibus, 

 rotundatis, 150 /x diam., ostiolo minuto perforatis, atris, glabris, 

 nitidis; ascis oblongis, breviter pedicellatis, 70-90 x 20 /x, vertice 

 rotundatis; sporidiis distichis, flavis, oblongo-clavatis, muriformi- 

 bus, basi attenuatis, 20-25 x 7-9 /x, junioribus inaequaliter uni- 

 septatis, hyalinis, ad septum constrictis (ad instar Sphaerellae), 

 dein 4-5-septatis, locuHs 1-3 septo longitudinaH divisis, ad septum 

 primarium semper evidentissime constrictis.
