Collection and habitat data.

Members of this genus are associated with polypore species on old logs (Newton et al. 2001). In New Brunswick, Toxidium gammaroides was found in mature hardwood forests and in a mixed forest. Adults were collected from a group of Pholiota sp. on the base of a dead standing American beech and in polypore fungi under bark. Adults were also captured in Lindgren funnel traps. This species was collected during June, July, and September.
