Hedgcock and Hunt: Notes on Coleosporium 251 



H. saxicola Small : Georgia. 

 H. strumosus : Alabama. 



H. tuberosus : Alabama, South Carolina and Virginia. 



Coleosporium helianthi has been successfully inoculated upon the following 

 species : Pinus virginiana, Helianthus decapetalus, H. divaricatus, H. glaucus, 

 H. microcephalics and H. radula. 



Coleosporium inconspicuum, according to our records, has been collected in 

 the United States as follows : 



O and I on Pinus : 



P. echinata: Georgia and North Carolina. 

 P. palustris : South Carolina. 



P. virginiana: District of Columbia, Georgia, Maryland, North Carolina and 

 Virginia. 



11 and III on Coreopsis : 

 C. delphinifolia : Tennessee. 



C. lanceolata : North Carolina and Tennessee. 



C. major: Georgia, North Carolina, South Carolina and Tennessee. 

 C. major oemleri: Georgia, North Carolina, Tennessee and Virginia. 

 C. major rigida: Georgia, North Carolina and Tennessee. 

 C. tripteris : Georgia and Tennessee. 



C. verticillata : District of Columbia, Maryland, North Carolina and Virginia. 



Coleosporium inconspicuum has been successfully inoculated 

 upon the following species : Pinus virginiana, Coreopsis lanceolata, 

 C. major, C. verticillata and C. tripteris. 



From the foregoing data, it will readily be seen that Coleospo- 

 rium helianthi has a much wider known distribution in the United 

 States than Coleosporium inconspicuum, as it ranges from Min- 

 nesota and New York on the north to Louisiana and Georgia on 

 the south, as compared with a range for C. inconspicuum from 

 Maryland and Michigan south to Georgia and west to Tennessee. 



Coleosporium terebinthinaceae 



Coleosporium terebinthinaceae (Schw.) Arthur was first de- 

 scribed in the uredinial stage as Uredo terebinthinaceae by Schwei- 

 nitz 12 in 1822. It was transferred to the genus Coleosporium by 

 Professor Arthur 13 in 1907. The aecial form was discovered by 

 the senior writer in 1916, and described in 191 7. 14
