Natural history.

Two individuals of Gyrophaena brevicollis were collected from Polyporus squamosus ( Polyporaceae) on a dead standing silver maple in a silver maple forest. One specimen from ON was collected from gilled mushrooms (Brunke et al. (2012), otherwise little is known about the habitat association of this species.

Distribution in Canada and Alaska.

ON, NB (Bousquet et al. 2013). Brunke et al. (2012) reported this species for the first time for Canada from several sites in southern ON.

Comments.

Except for a slight difference in the shape of male tergite VIII, the NB specimen agrees with the description and illustrations in Seevers (1951) for Gyrophaena brevicollis . We have noted that the shape of the male tergite is variable in other Gyrophaena species (Klimaszewski et al. 2009b).
