orange color changing to brown, in its whitish tubes and in its stem 

 approaching the pileus in color. 



Camarosporium maclurae n. sp. 



Perithecia gregarious, about .3 mm broad, nestling in the bark, 

 erumpent, conic or subglobose, scarcely papillate, black; spores at 

 first simple and hyaline, then colored and 3-5-septate and muriform, 

 sometimes slightly curved, 15-20x8-10 fi. 



Dead branches of osage orange, Madura p o m i f e r a (Raf .) 

 Schneid. Orient Point. April. R. Latham. 



The apertures in the epidermis through which the fungus breaks 

 are either orbicular or subelliptic. 



Centaurea maculosa Lam. 

 Granville, Washington co. September. F. T. Pember. An 

 introduced species. 



Cercospora medicaginis E. & E. 

 Living leaves of alfalfa, Medicago sativa L. Geneva. 

 June. F. C. Stewart. 



Cercosporella terminalis n. sp. 



Spots narrowly oblong, 1-3 cm long, 3-5 mm broad, often con- 

 fluent, specially at the apical end of the leaf which is commonly 

 entirely discolored, brown or blackish brown, often sterile ; -tufts 

 mostly effused, forming linear flocculent white patches ; spores 

 variable, curved or flexuous, subcylindric or gradually tapering 

 toward the apex, continuous or 1-3-septate, often nucleate, 50-150 x 

 3-5 fi, supported on short simple or obscure hyphae. 



Leaves of Indian poke, Veratrum v i r i d e Ait. Edwards, 

 St Lawrence co. May. 



This species is closely related to Cercosporella veratri 

 Pk. from which it is easily distinguished by its earlier appearance 

 and by the different character of the spots. Their habit of becoming 

 confluent and discoloring the whole apex of the leaf has suggested 

 the specific name. Notwithstanding the obscure character of the 

 hyphae, a careful search even in young and slightly discolored spots 

 failed to detect any acervuli. 



Clavaria subtilis Pers. 

 Among fallen leaves of spruce trees. North Elba. September. 

 In some of the specimens the tips of the ultimate branchlets have 

 retained their pure white color.
