tioliim papilliforni. Asci clavate-evliudrical 50-55 x 7-8 />.. with 

 abundant filiform paraphyses. Sporidia biseriate, fusoid-oblong, 3- 

 septate, slightly constricted at the septa, olive-brown 12-14 x 3-3? /-/.. 



Melanomma tetonensis. 



On bark of Artemisia cana, Valley of the Teton river in north- 

 ern Montana, July, 1889, Anderson, 551. Perithecia scattered, 

 erumpent-superficial, ovate-globose, nearly smooth, 5-I mm. diam. 

 collapsing above. Ostiolum narrow and only slightly prominent. 

 Asci clavate-oblong, 75-80 x 18-20 jj.. with abundant paraphyses. 

 Sporidia crowded, subbiseriate, fusoid-cylindrical, slightly curved, 

 yellow, 5-septate, 22-27 x 6-7 ,«. ends acute while lying in the asci, 

 obtuse when free. This differs from M. occidetitalis (Ell.) in its 

 scattered mode of growth and larger perithecia and sporidia, the 

 latter being constantly 5-septate and not constricted at any of the 

 septa. It might be considered a var. of that species. 



Melanomma parasiticum. 



On old Diatrype stigma, Newfield, N. J., April, 1889. Perithecia 

 scattered or gregarious, superficial, ovate-hemispherical, 110-130 ;jl. 

 diam. roughish, black. Ostiolum papilliform soon perforated. Asci 

 oblong cylindrical 40-50 x 8-10 /j-. sessile, without paraphyses. 

 Sporidia crowded-biseriate, oblong-fusoid, 3-septate, and finally 

 slightly constricted at the septa, 10-12 x 3-4 //. pale olivaceous. 

 Sphaeria nigerrima, Blox. (Cke. Hndbk. No. 2812) which is also 

 parasitic "on various species of Diatrype" has sporidia 122-20 p.. 

 long and at length multiseptate and perithecia " sprinkled with short 

 stiff bristles." Our specimens of 31. vile Fckl. have the perithecia 

 larger and differ otherwise. Melanomma subsparsum Fckl. which 

 we have not seen is said to have yellow sporidia. 



Winteria tuberculifera. 



On bark of wild plum (Prunus) London, Canada, 1890. Dearness, 

 1533. Perithecia gregarious, superficial, 2 mm. diam. depressed-glo- 

 bose, narrowed below, tubercular roughened, collapsed and cup- 

 shaped when dry, black. Asci 35-40 x 5-6 p.. Sporidia crowded- 

 biseriate, fusoid-oblong, hyaline 2-4 nucleate 6-8 x 2-2?//.. (becoming 

 1-3 septate) ? 

 Cucurbitaria kelseyi. 



Perithecia large (4-I mm.) rough, subglobose, regularly rounded 

 above with a papilliform ostiolum, bursting through cracks in the 

 bark in elongated tufts, crowded and subconfluent, connected below
