Abstract

In 2009, unusual white pine needle discoloration was observed in eastern Canada and the USA. While the symptoms were similar in most pine stands, the disease was diagnosed as Canavirgella bandfieldii in several locations and Dooks needle blight caused by Lophophacidium dooksii in others. Due to the similarity in symptom development and morphological features of the causal agents, it was suspected that C. bandfieldii and L. dooksii are either the same species or closely related taxa. To test this hypothesis, we examined 20 collections representing C. banfieldii and L. dooksii, including the two type specimens. Phylogenetic analyses of ITS sequences confirm the synonymy of C. bandfieldii with the earlier described L. dooksii and provide the first evidence of the close evolutionary relationship of L. dooksii to other pine pathogens
