Sphaeropsis Smilacis Ellis & Ev. is a Melanconium. Prof. 

 Peck's var. on Smilax hispida founded on a collection by Dr. 

 Fairman in Yates Co., N. Y., 1909, is a good Sphaeropsis. The 

 pycnidia are thickly scattered, .25 mm. in diameter, minutely 

 puncturing the epidermis. " Conidia 17-20 X n-i3ju." — Peck. 

 Exceptional spores vary from 12-25^ in length and in shape 

 from globose to oblong-elliptic. Collections examined, Kansas, 

 1906, Bartholomew; London, Ont, 1895, Dearness; Long Island, 

 N. Y., 1916, House. 



25. Haplosporella Burnhami sp. nov. 



Stromata irregularly globose to linear, 2-10 mm. Pycnidia 

 partly immersed, connate at base, their position indicated by nar- 

 row rifts in the bark, mostly about .2 mm. in diameter; ostiola 

 various, a mere perforation or a cylindric or conic beak ; flesh 

 whitish at first, becoming gray. Conidia oblong-elliptic with 

 rounded ends or pyriform, brown at maturity, 1-2-nucleate, 18- 

 24 X 10-12 fi; conidiophores rather stout, some of them as long 

 as the spores.

 Torr., Washington Co., N. Y., May, 1916, S. H. Burnham 112. 



Sphaeropsis Sumachi (Schw.) Cooke & Ellis is described as 

 having subconfluent perithecia in dark stromata, — so possibly it 

 may be a Haplosporella. Mr. Burnham' s material has been com- 

 pared with specimens on Rhus glabra and R. hirta named S. 

 Sumachi by Dr. Peck and by Mr. Ellis. There seems more differ- 

 ence in the specimens than is implied in the descriptions. 



26. Septoria samarae-macrophylli Dearn. & Barth. sp. nov. 



Spots conspicuous, reddish-brown, subcircular areas in the 

 wings of the samarae, 2-5 mm. in diameter. Pycnidia pale, thin- 

 walled, 80-1 20 fx. Sporules numerous, continuous or 1-2 sep- 

 tate, some of them minutely guttulate, 30-65 X 2-2.5 l ess 

 curved and thicker than in S\ aceris-macrophylli Peck ; spots 

 quite distinct from those of 5. circinata Ellis & Ev. and from 

 S. samarae Peck on keys of Acer negundo.
