PcritlH'cia scattered, depressed-globose, 150-300 n. diam., buried, 

 but raising the epidermis into .-Iron"-, hemispherical protuberances, 

 finally deciduous. Ostiolum subglobose-papillate, black, rough, erum- 

 pent. Asci clavate, attenuate-stipitate, 90-100x12 //, paraphysate. 

 Spuridia biseriate, fusoicl or clavate-fusoid, 20-25 x 4-5 /*, endochrome 

 4-6-parted, mostly 5-parted, pale yellow. 



On dead stems of Juncus, lona, N. J. 



The sporidia are at first surrounded with a broad, gelatinous 

 envelope which disappears together with the bristle-like apical appen- 

 dage. The measurements here given apply to the body of the sporid- 

 iuni and do not include the envelope. Specc. of L. apogon, S. & S. 

 in Kriegers Sax. Fungi, 130, are quite different from this. L.juncina, 

 Awd. (Myc. March. 2140) has much smaller and less prominent peri- 

 thecia. 



M. hyalospora, (Saec.) 



Leptosphceria hyalospora, Sacc. F. Yen. Ser. II, p. 323, F. Ital. tab. 273. 

 Metasphceria hyalospora, Sacc. Syll. 3497, Cke. Syn. 4495, 

 Exsicc. EH. N. A. F. 587. 



Perithecia gregarious but separate, erumpent-superficial, rather 

 less than \ mm. diam., globose, black. Ostiolum rather acutely coni- 

 cal, becoming narrowly perforated. Asci densely fasciculate, cylin- 

 dric-subclavate, 90-100x10-12 //, often flexuous, 8 spored, with a 

 short, nodulose stipe, and with filiform paraphyses. Sporidia fusoicl. 

 28-32 x 5|-6| //, obtusely acuminate at each end, somewhat curved. 

 8-guttulate, then torulose, 7 -septate, hyaline. 



On decaying stalks of Zea Mays and on culms of Panicum rrtm- 

 gaUL Newfield, N. J.. and on Sabal Palmetto, Louisiana (Langlois). 



Both the New Jersey and Louisiana specc. have the sporidia 35- 

 45x7-9 //, 9~12-septate and slightly curved. 



C. On cryptogamous plants. 

 M. epipteridea, (Cke. & Hark.) 



Sphceria epipteridis, Cke. & Hark. Grev. IX, p. 8. 

 Metaspluzria epipteridea, Sacc. Syll. 3513, Cke. Syn. 4513, 



Scattered, covered or erumpent and semiimmersed, black. Asci 

 clavate, sessile. Sporidia fusoid, hyaline, 3-5-septate, 22-25 x 5 //. 

 On stipes of Pteris aquilina, California. 



M. Lycopodii, (B. & C.) 



Sphceria Lycopodii, B. & C. Grev. IV, p. 155, 

 Metasphceria Lycopodii, Sacc. Syll. 3511, Cke. Syn 4511. 



Punctiform, quite covered by the cuticle, not the least projecting.
