Decay and canker caused by Inonotus rickii spreading on more urban tree species
Inonotus rickii was detected for the first time causing cankers and decay in Acer negundo and Celtis australis in Italy. In a boxelder boulevard, declining trees showed sparse foliage, exudations and cracks in the bark; in some cases, chlamydospore masses were present. Five isolates were collected and compared by growth tests in vitro and electrophoretic analyses; three isolates from the same boulevard showed very similar physiological characters. The increasing importance of the pathogen in urban areas is underlined and discussed.
