Phialophora melinii: Inoculations in Wounded Red Maple. Alex L. Shigo, Chief Plant Pathologist, U.S. Forest Service, U.S. Department of Agriculture, Northeastern Forest Experiment Station, Durham, NH 03824; Phytopathology 67:1333-1337.

Isolations from discolored wood associated with wounds previously inoculated with Phialophora melinii in Acer rubrum showed that the fungus was present in all 1.5- to 26-mo-old wounds. Hymenomycetes from natural sources were not isolated from wounds less than 4 mo old. Wounds on trees inoculated with P. melinii yielded fewer Hymenomycetes than did noninoculated wounds. The fungus thus acted as an aggressive invader and a long-term inhabitant of discolored wood.
