111 the single specimen seen, the central part of the stroma was par- 

 tially decayed while the digitate extremities were still fresh. Belongs in 

 subgenus Clintoniella, Sacc, Syll. II, p. 532. 



Leptosph^ria SPARTm^, E. & E.— Perithecia gregarious (about i 

 mm.), covered by the blackened cuticle which is raised into little promi- 

 nenv;es over them and pierced by the papilliform and at length broadly per- 

 forated ostiolum. x\.sci 115—120 x 12—15 /^-, surrounded by abundant para- 

 physes and containing eight two-ranked, broadly fusiform, pale-yellowish, 

 5-septate, 35-45 x 8—10 sporidia. 



Leptosph^kia sticta, !E. & E.— Perithecia scattered, subovate, 

 membranaceous, buried under the blackened epidermis, which is pierced 

 but not raised by the punctiform ostiola. Asci 100—125 x 15—20 !->-, with 

 abundant pnraphyses. Sporidia 1 or 2-seriate, fusiform, pale yellow, 5- 

 septate, very slightly constricted at the septa, ends obtuse, 30 —40 x 7 — 9 /->■. 



Distinguished by its punctiform ostiola, which are the only outward 

 indication of the buried perithecia. The ostiola are much the same as in 

 Hypoxi/lon pimctulatum, B & Rav., appearing under the lens like punct- 

 ures made by the point of a pin. The fruit is scarcely different from that 

 of the preceding species. 



In this and the next species, the part of the culm occupied by the 

 perithecia is uniformly blackened. 



Leptosph^ria MARINA, E. & E.— Perithecia irregularly scattered, 

 subelliptical, (i— f mm.), upper part hemispheric-conic, projecting, closely 

 covered by the blackened epidermis, apex subtrunca'e with a papiliform 

 ostiolum which is soon deciduous, leaving abroad opening. Asci 112 — 

 150 x 25—35 narrowed into a substipitate base. Sporidia 2— 3-seriate, 

 fusiform or clavate-fusiform, yellowish, 1— 3-septate (mostly 1-septate), 

 slightly constricted at the middle, septum, 50—60 x 10—12 /^-, ends sub- 

 obtuse. In this case, the gre iter number of septa does not seem to indi- 

 cate maturity. The perithecia are more prominent and the sporidia much 

 longer than in L. discors, S. & E. 



This and the two prdceding species were collected during the summer 

 of 1884, by Mrs. Caroline Treat at Cape May, N^. J., on dead culms of 

 Spartina lying on the beach. 



Leptosph^ria clavicarpa, E. & E.— Perithecia mostly seriate in 

 lines i — 1 cm. long, covered by the blackened epidermis which is raised 

 into a ridge above them and perforated by the inconspicuous ostiola. 

 Asci broad, oblong-c>'lindrical, 75—100 x 22—25/^-, obtuse, with a short, 

 narrow base. Paraphyses filiform. Sporidia crowded in several series, 

 clavate-oblong, slightly curved, obtuse and rounded above, narrowed 

 rather abruptly below, 7-9 septate, and when mature, deep yellow-brown, 

 25 — 40 X 8—10 ,a, only slightly constricted at the septa. Spermatia in 

 similar perithecia, oblong-cylindrical, slightly curved, hyaline, 3— 5x Mp-. 



The general appearance is that of Sphceria orthogramma, B. & C. 

 Leptosphceria culmifmga (Fr.) has longer, narrower sporidia, and the 

 perithecia are not usually so distinctly seriate. Found on dead culms of
