Material examined.

New Brunswick, Sunbury Co., Acadia Research Forest, 46.0188°N, 66.3796°W, 17.VIII.2007, R. P. Webster, mature red spruce and red maple forest, in decaying fleshy polypore fungi on standing dead spruce (1 ♂, AFC). Restigouche Co., vic. Summit Depot, 47.7836°N, 68.3227°W, 21.VII.2010, M. Turgeon & R. Webster, clear-cut, on decaying Climacodon septentrionale on dead (standing) yellow birch (1, RWC); Dionne Brook P.N.A. 47.9030°N, 68.3503°W, 9.VIII.2011, R. P. Webster, old-growth northern hardwood forest, on Climacodon septentrionale (Fr.) P. Karst. on sugar maple (2, RWC).

Collection and habitat data.

Specimens of this species from New Brunswick were collected from a decaying fleshy polypore mushroom on a standing, dead spruce in a mature red spruce forest, from a decaying Climacodon septentrionale (Fr.) P. Karst. on a dead, standing yellow birch in a recent clearcut (boreal forest area), and from a (fresh) Climacodon septentrionale (Fr.) P. Karst. on a living sugar maple in an old-growth northern hardwood forest. Four individuals were collected in company with Lordithon niger (Gravenhorst) from a decaying fleshy polypore fungus on a standing, dead Populus sp. in a hardwood forest (sugar maple and American beech) in Saint-Raphaël (15.VII.2006), Quebec (Webster, unpublished). One specimen from Tennessee (USA) was sifted from leaf litter. Little was previously known about the habitat and biology of this rare species. Campbell (1973) suggested that this species lived in some restricted habitat, such as mammal burrows. The habitat data above suggest that this species may be associated with decaying fleshy polypore or polypore-like fungi on standing dead and living trees. Adults were collected during July and August.

Distribution in Canada and Alaska.
