On dead stems of Solanum dulcamara, Ridgeway, Orleans Co., N. 

 Y., May, 1889. 



This might be referred to V. Dematium, but until the limits of that 

 species are fixed we propose this as new. 



9. Phoma Weldiana, n. sp. 



Perithecia few, scattered, black, shining, small, oval or rotund. 

 25-30 //. diam. Spores oblong, pointed at one end abruptly, or both at 

 times rounded, 10-15x3 //. 



On decorticated wood of Euonymus atropurpureus. Lyndonville, 

 N. Y., May, 1889. 



Name (Weldiana) after Miss L. A. Weld, who has assisted me in 

 the determination of host plants and in the preparation of the plates. 



10. Phoma albovestita, n. sp. 



Cortical spots mostly surrounded by a white zone, most apparent 

 before rupture. 



Perithecia small, erumpent, nestling in the inner bark, occasion- 

 ally clustered, dull black. Spores oblong, ends obtusely rounded. 

 4-7x1^-2 /'• 



On bark of Juglans einerea, May, 1 889. 



11. Phoma Lyndonvillensis, n, sp., (Plate 3, fig. 4). 

 Occupying faded spots on the stem. Perithecia ostiolate filled 



with minute oval or oblong sporules, sometimes nucleated, 3-6 ft. diam. 

 On stems of Malva rotundifolia, April, 1888. Found on the stems 

 of plants which had been attacked the previous fall by Septoria malvicola 

 E. and M. Both the Phoma and Septoria may be connected as states of 

 some higher or ascomycetous fungus. In the spring, as early as the snow 

 has. gone, one can find, on the green stems of the Malva, here and there, 

 bleached or dead spots, generally one inch long on which the Phoma 

 grows. There is a Phoma Malvacearum, but the above peculiar growth 

 has induced me to separate our plant. 



12. Phoma Rudbeckiae, n. sp. 



Perithecia numerous, erumpent, globose depressed, ostiolate, light 

 black. Sporules oblong, rounded at the ends, 4-6 ft. long, 2-3 ft. broad, 

 hyaline. 



On dead stems of Rudbeckia laciniata, Lyndonville, N. Y,> 

 April, 1888. 



13 Septoria Fairmani, E. and E. 



Jour Mycol., vol. 5, page 151. 



On living leaves of hollyhock (Alt/uza rosea), Lyndonville, N. Y.,.
