The specimens listed above were in part included in the 191i') list under 

 No. 101, Oymnoconia mtermtialis (Schlecht. ) Lagerh. Recent studies by 

 Kimkel have shown that there are two forms of the orange rust of black- 

 berries and raspberries, one a Caeoma with an Endophyllnm-like life his- 

 tory and the other an opsis-Puccinla-like form. The former has been sep- 

 arated by Dr. Arthur (1. c.) as a new genus, Kunkelia. For the sake of 

 emphasis this name is used alxive, though it should be recognized that there 

 is considerable difference of opinion as to the relationship of the two 

 forms, esix^cially in view of very recent investigations by Kunkel (Jour. 

 Agr. Res. 19:501-512. 1920) and Clinton (Conn. Agr. Exp. Sta. Bull. 222: 

 469-473. 1920). The writer is inclined to believe that we have here a rust 

 whicli is in an advanced stage of an evolutionary transition from a long 

 to a short cycled form, the transition taking place in the direction of the 

 aecium and the long cycled form surviving in certain regions and on certain 

 hosts.

This, the leaf rust of barley, was collected for the lirst lime in Indiana as 

 indicated above. A number of other collections in various counties of the 

 state have since been made, indicating that the rust was not uncommon in 



1918. but was not present in severe form. Tsn.illy the infection was very 

 slight and required careful search to find it. 



Tranzschel has shown that this rust in Russia has its aecia on Oniitho- 

 galum umhellattim and O. narhoncnse (Myc. Cent. 4 :70. 1914). Aecia havt- 

 not been collected in North America.
