Decay resulting from increment borings varies with tree species. Trembling aspen (Populus tremuloidcs Michx.) in Newfoundland is seriously affected by this particular wound. Three years after 20 trees had been bored, none had healed probably because of a pronounced split of the bark. The wood discoloration extended horizontally to about 2 cm on each side and vertically half metre above and below the wound. Peniophora polygonia (Pers. ex Fr.) Bourd. et Galz. was the most common fungus isolated while Polyporus adustus Willd. ex Fr. and several imperfect fungi and bacteria were also present.
