Notes: An Unusual Witches' Broom on Black Spruce Caused by Eastern Dwarf Mistletoe
Abstract:An unusual witches' broom on black spruce caused by eastern dwarf mistletoe is described. This broom carried, distally, mature cones with viable seeds. The endophytic system of the parasite was not found above the lowest branches of the broom. It is suggested that this condition was related to cone production.
