Heald-Wolf: New Species of Texas Fungi 



15 



Cercospora aurantia 



Maculis atro-brunneis, flavidis cinctis, 6-10 mm. lato ; hyphis 

 fertilibus hypophyllis, brunneis, septatis, denticulatis, vel nodu- 

 losis; conidiis dilute brunneis, clavatis, pluriseptatis, 75-135 X 

 4-5 P" 



On Citrus Aurantium L. Falfurrias, 2446 (type). 



This fungus forms large spots, 6-10 mm. in diameter, and 

 suborbicular except when they are marginal. They are dark- 

 brown in color with a lighter brown center and surrounded by a 

 region of yellow which fades out into the green of the leaf. The 

 conidiophores, formed on the lower surface in small groups, show 

 plainly the points of attachment of the conidia. 



Cercospora Capsici 



Maculis rotundatis, 1-7 mm. diam., primo brunneis deinde pal- 

 lescentibus brunneis, zona flavida cinctis ; conidiophoris amphi- 

 genis, brunneis, 10-15-fasciculatis, septatis, 30-60X4.5-5.5/*. 

 Conidiis plerumque rectis, clavatis, dilute brunneis, septatis 

 paucis, 75-125 X4-5 



On Capsicum annuum L. Cuero, 2592 (type). 



Leaves infested with this fungus form spots 1-7 mm. in 

 diameter, mostly circular or subcircular. The spots are raised on 

 the upper surface, brown at first, later becoming grayish-brown. 

 They are margined by a very definite darker zone outside of 

 which is a more or less extended halo of yellow. Where the 

 spots are abundant the leaves become chlorotic, wilt and fall. 



Cercospora Chrysanthemi 



Areis superne elevatis, inferne depressis, 2-10 mm. lat., 

 margine elevata, subcircularibus vel irregularibus, brunneis 

 maturitate griseolis. Conidiophoris amphigenis, dense aggregatis, 

 septatis, 40-75 X 4 p ', conidiis clavatis, pluriseptatis, subhyalinis, 

 40-120 X 4 ^. 



On Chrysanthemum sp. San Antonio, 1659 (type). 



The diseased areas are raised above and sunken below and vary 

 much in size. They have very definite elevated borders, are 

 subcircular or irregular in outline, and brown in color, becoming 

 gray with age. When the spots are abundant, the leaf becomes 

 brown between the diseased areas.
