asci. Rostrup, in his Greenland Fungi, reports S. Luzuloe, Cke., on 

 Z/uzula confusa, but gives no measurements. 



S. Scirpi lacustris, Awd. Myc. Eur. Pyr. p. 18, fig. 73. 



Perithecia scattered, sunk in the surface of the leaf, carbonaceo- 

 coriaceous, somewhat brittle, depressed-spherical, pierced above, black, 

 150-180 fi diam. Asci clavate-oblong, attenuated into a short stipe 

 below, 8-spored, 55-68 -x 14 //. Sporidia 3-seriate, elongated-fusoid, 

 obtuse at the ends, slightly curved, uniseptate, not constricted, hyaline, 

 24-27 X 4-5 /i. 



On Scirpus ccespitosus, Sukkertoppen, Greenland. 



S. Wichuriana, Schrot. Nord. Pilze, p. 12. 



Perithecia gregarious, innate, very small, sphaeroid, 50-65 /i 

 diam., glabrous, texture loosely areolate, ostiolum obsolete. Asci few, 

 aparaphysate, ovoid, 22-26 x 14-16 fi, sessile, 8-spored. Sporidia 

 conglobate, fusoid, 11-1 3 x 3-3^ fi, hyaline, uniseptate, not constricted. 



On leaves of various species of Carex, and on Eriophorum an- 

 gustifolium and Alopecurus alpinus, Greenland. 



S. pasilla, Awd. 1. c. p. 17, fig. 115. 



Exsicc. Rab. F. Eur. 2440.— Thum. M. TJ. 1355. 



Perithecia epiphyllous, sunk in the surface of the leaf, thickly 

 scattered, spherical, pierced above, black, 50-!-70 fi diam. Asci ovate- 

 oblong, sessile, 8-spored, 40 x 12-14 //. Sporidia 3-4-seriate, oblong- 

 fusoid, somewhat thickened above, ends obtuse, nearly straight, con- 

 stricted at the septum, with 4-5 oil globules, hyaline, 22-24 x 3-4 //. 



On various species of (Jyperacece and Qraminece, viz., Kobresia 

 caricina, Carex (several species), Festuca rubra, Phleum, alpinum, 

 Alopecurus alpinus and Nardus strictus, Greenland. 



S. leptopleiira, De Not. Reel. Pyr. Comm. II, p. 488. 



Perithecia gregarious, often seriate between the nerves of the 

 sheath, membranaceous, thin, black, broadly perforated above, about 

 200 n diam., covered by the epidermis through which they are so 

 plainly visible as to appear entirely bare, not strongly prominent, and 

 more or less collapsing. Asci cylindrical, subsessile, 45-50 x 6 //, 

 without paraphyses. Sporidia biseriate, oblong-cylindrical, straight or 

 slightly curved, about 15 x2|-3 [i. 



On Secale cereale (sheaths of the leaves), Alabama (Atkinson). 



There can not be much doubt that this is the species named, 

 though we have no specimen for comparison. No septa could be seen 

 in the sporidia but the specc. were not fully mature.
