European larch canker, caused by Lachnellula willkommii, was found in 1981 in Washington County, ME, infecting eastern larch (Larix laricina) stands. In most locations, only branch cankers were observed. In two stands, numerous stem cankers were found and a few trees had died. The age of the oldest cankers indicates the disease had been in the area for at least 11 yr.
