KUNKELIA ARTHUR 

 Bot. Gaz., vol. 63, p. 504, 1917. 



This genus is based upon the fact, first shown by Kunkel (Bull. 

 Torr. Bot. Club, vol. 40, p. 361, 1913, Am. Jour. Bot., vol. 1, p. 37, 

 1914), that the entire life cycle consists of a caeomoid stage associated 

 with pycnia, the spores of which germinate like teliospores. It is not 

 distinguishable morphologically from the aecial stage of the genus 

 Gymnoconia, but the aecial spores of the genus last named germinate 

 like true aecia spores, and there is an alternate stage not distinguish- 

 able from the telia of the genus Puccinia.
