Collection and Habitat data. No biological data associated with the NH record. Canadian data: in mixed forest, young mixed forest, fir forests, eastern white cedar swamp, mature red spruce forests, red maple forest, and red oak forest; on/in gilled mushrooms on forest floor, on log, and on a stump, on small gilled mushrooms on side of decayed log; in rotting mushrooms, in an orange bracket (polypore) fungus, on bracket fungus on white birch, and on Pleurotus sp. on dead standing Populus tremuloides ( Klimaszewski et al. 2009c, 2018).

Material. USA, New Hampshire, Carroll Co.: Intervale, A. Fenyes ( Seevers 1951).

Comments. More research is needed to determine the status of the Nearctic and Palearctic populations, though the level of genetic divergence between discrete Nearctic and Palearctic populations suggests that two sister species are involved (Brunke et al. 2021).
