Perithecia gregarious (about 1 mm.), covered by the blackened 

 cuticle which is raised into little prominences over them and pierced by 

 the papilliform and at length broadly perforated' ostiolum. Asci 115- 

 120x12-15 fjL, surrounded by abundant paraphyses, and containing 

 eight two-ranked, broadly fusiform, pale yellowish, 5-septate, 35-45 x 

 8-10 fi sporidia.

 Atlantic City, N. J. 



This must be very near L. incarcerata, B. & C, but in that 

 species the perithecia are said to lie under " a little clouded speck in 

 the cuticle opening by a little longitudinal fissure," while in L. Spar- 

 tinm the surface of the culm is uniformly blackened and raised into 

 little pustules by the subjacent perithecia, and these pustules are not 

 longitudinally cleft, but merely perforated by the papilliform ostiola.

Perithecia scattered, subovate, membranaceous, buried under' the 

 blackened epidermis, which is pierced but not raised by the punctiform 

 ostiola. Asci 100-125x15-20 (i, with abundant paraphyses. Spo- 

 ■ridia 1 or 2-seriate, fusiform, pale yellow, 5-septate, very slightly con- 

 stricted at the septa, ends obtuse, 30-40 x 7-9 fi. Distinguished bj- 

 its punctiform ostiola, which are the only outward indication of the 

 buried perithecia. The fruit is scarcely different from that of the pre- 

 ceeding species. The part of the culm occupied by the perithecia is 

 uniformly blackened.

We have compared L. sticta, B. & E. with an authentic spec, of 

 L. albopunctata, West., sent us by Prof Oudemans, and it is undoubt- 

 edly the same.
