* Pathogenicity was proved by inoculation of the isolated strain into the respective plant species, development of typical wilt symptoms, and reiso- 
ion of the fungus. 
> Susceptibility was proved by inoculation with inoculum containing at least four different host isolates of V. albo-atrum, production of typical wilt 
nptoms, and reisolation of the fungus. 
“Inoculated with a strain of V. albo-atrum from the sugar maple. The fungus was reisolated 2 months later from twigs having faint green streaks. 
) leaf symptoms were observed. 
Verticillium spp. isolated. The fungus was not characteristic of V. albo-atrum.
