Collection and habitat data.

The New Brunswick specimens of Placonotus zimmermanni were captured in Lindgren funnel traps deployed in a mature hardwood forest with American beech ( Fagus grandifolia Ehrh.) and sugar maple and in an old silver maple swamp. Adults at the latter site were captured in traps in the forest canopy. Majka (2008) reported this species from a red oak forest (window trap) in Nova Scotia. Thomas (1993) reported collecting this species from under bark of dead hardwoods, including oaks, in association with ascomycete fungi.
