Melanomma asterostomum E. & E. 



On bark of beech roots, Grauton, Ontario, Canada, Jan., 1894 

 (J. Dearness, No. 2,238). 



Perithecia gregarious, ovate-conical, rough, black, 4-3 mm. diam., 

 with a conic-papilliform, often distinctly radiate- sulcata 4-5 cleft 

 ostiolum. Asci clavate-cylindrical, 8-spored, paraphysate, p, sp. 45- 

 50 X 8-10//. Sporidia crowded-biseriate, oblong-fusoid, 3-septate, 

 often constricted at the septa and one of the inner cells smaller, pale 

 olivaceous-brown (nearly hyaline at first), 12-15 x 3-4//. 



Differs from M. fuscidulum Sacc. , in the shape of the perithecia 

 and very different ostiolum. 



Melanomma moricolum E. & E. 



Perithecia gregarious, scattered, semi-erumpent, sub-globose, 1 mm. 

 diam., with a minute papilliform ostiolum. Asci clavate-cylindrical, 

 short stipitate, paraphysate, 8-spored, p. sp. 40-45 x 7//. Sporidia 

 biseriate, oblong-fusoid, slightly curved, sub-obtuse, yellowish- brown, 

 12-15 X 3-4//, mostly not constricted, but when mature, some of 

 them distinctly so. 



Differs from M. Mori H. Fabre, in its much shorter asci and 

 rather smaller biseriate sporidia. 



On dead small limbs of Morns, Rockport, Kansas (Bartholomew, 

 No. 1,447 partly). 



Melanomma alpestre E. & E. 



On dead twigs of Ardostaphylos Nevadensis, Mt. Paddo, Wash., 

 July, 1886, Alt. 6,000-7,000 ft. (W. N. Suksdorf, No. 268). 



Perithecia scattered, hemispherical, 1-11 mm. diam., carbonace- 

 ous, black, glabrous, superficial, flattened, with a minute papilliform 

 ostiolum. Asci cylindrical, short-stipitate, paraphysate, 110-150 x 

 10-12//. Sporidia overlapping-uniseriate, or (in the longer asci) 

 lying end to end, oblong-cylindrical, obtuse, slightly curved, 3-sep- 

 tate, brown, 18-22x5-6//.. 



One perithecium contained two distinct ascigerous nuclei, seeming 

 to indicate that the outer, black shell described above as a perithecium, 

 is in reality a stroma, but the material was too scanty to enable us 

 to settle this point definitely and we havQ, therefore, referred the 

 specc. to Melanomma. 



Melanomma dealbatum E. & E. 



On old decorticated, bleached and weather-beaten cottonwood logs, 

 Rockport, Kansas, Feb., 1894 (Bartholomew, No. 1,369).
