Material

(non-sequenced material). Canada: Quebec: Gatineau Park , wolf trail, near trail start, 45.541, -75.912, hardwood forest, Polyporus squamosus on large beech log, 8.VI.2019, A. Brunke & J. Smith (1, CNC) .

Distribution.

Origin. Nearctic. Canada: NB, QC [new record]. United States: WI.

Bionomics.

Specimens have been collected from a partly dried Pleurotus mushroom, from within the pores of a Trametes polypore, and from the nest contents of a Barred owl ( Strix varia Barton) ( Klimaszewski et al. 2018). The specimen from QC was collected from Polyporus squamosus on a beech tree.

Comments.

The new record from QC, near the ON border, bridges the wide gap between previous records in NB and WI.
