Collection and habitat data
Hanley and Goodrich (1995b) considered Oxyporus rufipennis to have a relatively narrow range of host species (Pholiota (Cortinariaceae), Polyporus (Polyoraceae), Omphalotus, Pleurotus (Tricholomataceae)). In New Brunswick, this species was collected from mushrooms on standing trees and a recently fallen tree: Pleurotus sp. mushrooms on dead standing trembling aspen (Populus tremuloides Michx.), from masses of Pholiota sp. mushrooms on a large standing (partially dead) yellow birch (Betula alleghaniensis Britt.), and a recently fallen yellow birch. Adults were captured during June, July, and September.
