ON KETELEERIA NEEDLE RUST

WANG Yun-chang R.S. PETERSON(Institute of Microbiology, Academia Sinica, Beijing, China;St. John's College, Santa Fe, New Mexico, U. S. A.)  
Cronartium keteleeriae Tai is characterized by ribbonshaped columns of thin-walled, bright orange teliospores which are indistinguishable from those of Chrysomyxa weirii Jacks.This needle rust of Keteleeria lacks the telial peridium, telial matrix and thick walled teliospores of Cronartium. The authors propose the new combination of Chrysomyxa keteleeriae (Tai) Wang et Peterson. It differs from related microcyclic species mainly in its longer telial columns, to 6 mm high.
