Collection and habitat data.

Oxyporus quinquemaculatus has a relatively narrow range of hosts (five genera in three families), with most records from the genus Pluteus (Hanley and Goodrich 1995b). This species was also reported from Laccaria amethystina Murr., Psilocybe spadicea Fries, and Naematoloma sublateritium Karst. by Weiss and West (1920, 1921). In New Brunswick, this species was collected from gilled mushrooms (species not determined) and from Polyporus varius Fr. in mixed forests during June and July.
