(p. sp. 75-80) x 6 ',)., paraphysate, 8-spored. Sporidia uniseriate, 

 inequilaterally-elliptical, soon opake, 10-12 x 5 //. 



Rosellinia limoniispora E. & E. 



Proc. Acad., Phil. 1894, p. 326. The habitat of this species was 

 erroneously given as on leaves of Fraxinus. It should be on dead 

 shoots or limbs of Fraxinus buried in the ground. Mr. B. also 

 finds it on dead limbs of Ailanihus and of Juglans dnerea in similar 

 situations, its entire growth and development being subterraneous. 

 In the specc. on Ailanthus there are traces of a ' thin, light colored 

 (cinereous) subiculum more or less distinct. The young perithecia 

 are ovate-globose, but become more or less flattened above. 



Rosellinia muriculata E. & E. 



On inner surface of bark of Populus monilifera, Rockport, Kansas, 

 Dec, 1894. E. Bartholomew, No. 1,613. 



Perithecia superficial, ovate, slightly contracted below, 200-220 

 x 180-200 ,/, clothed with a short, white pubesence; ostiolum minute, 

 papilliform. Asci cylindrical, 75 x 6-7 <>. p. sp. 55-60 ,u. long. 

 Short-stipitate, paraphysate, 8-spored. Sporidia obliquely uniseri- 

 ate, oblong elliptical, pale brown, 8-10x4-5//. 



The white pubescence soon disappears, leaving the perithecia black 

 and muriculate-roughened. 



Melanopsamma borealis E. & E. 



On inner surface of loosened bark of fir trees, Newfoundland. 

 Rev. A. C. Waghorne. 



Perithecia gregarious, erumpent-superficial, ovate- globose, rough, 

 250-300 // diam., with a conic-papilliform ostiolum. Asci clavate- 

 cylindrical, 90-100 x 8-10//, with filiform, somewhat branched par- 

 aphyses. Sporidia uniseriate, oblong-ovate, uniseptate and con- 

 stricted, hyaline, 14-16 x 5;j-6j //.. 



Melanomma boreale E. & E. 



On weather-beaten wood. Newfoundland, Dec. 1894. Rev. 

 A. C. Waghorne. 



Perithecia erumpent-superficial, gregarious, ovate, about £ mm. 

 diam., subcarbonaceous, sometimes collapsing above. Ostiola at 

 first inconspicuous, at length conic-cylindrical, truncate. Asci clavate, 

 cylindrical, short-stipitate, paraphysate, 8-spored p. sp. 50-55x4- 

 5 /'. Sporidia obliquely uniseriate or subbiseriate above, oblong,
