Collection and habitat data.

Most adults of Mycetophagus serrulatus from New Brunswick were collected in hardwood forests (sugar maple and American beech, red oak) or mixed forests. Majka (2010) reported a specimen from a balsam fir ( Abies balsamea (L.) Mill.) forest. Adults were found on slightly dried Climacodon septentrionale (Fr.) Karsten on sugar maple, in polypore fungi on a large basswood ( Tilia americana L.) log, and in partially dried Pleurotus sp. on dead, standing sugar maples and trembling aspen. Adults were collected during June, July, August, and September.

Distribution in Canada and Alaska.

MB, ON, QC, NB, NS ( Bousquet 1991; Dollin et al. 2008; Majka 2010). Majka (2010) newly reported this species from New Brunswick from the Grand Manan archipelago, Kent Island (Charlotte Co.). This species is probably widespread in the province.
