Collection and habitat data.

All the records of this species from New Brunswick were from hardwood forests (sugar maple and American beech, red oak and red maple ( Acer rubrum L.)). Most adults were collected from partially dried Pleurotus species, including the oyster mushroom, Pleurotus ostreatus , on dead, standing sugar maples and a dead, standing poplar (probably trembling aspen). One individual was captured in a Lindgren funnel trap. Cline and Leschen (2005) also reported Mycetophagus punctatus from Pleurotus ostreatus . Majka (2010) reported other fungal associations with this species. Adults were captured during June and August.
