Collection and habitat data.

Scaphisoma rubens was found in a variety of forest types in New Brunswick. These included mature hardwood forests (sugar maple and American beech ( Fagus grandifolia Ehrh.)), mixed forests, a regenerating mixed forest, old eastern white cedar forests, an old red oak forest, a red oak and red maple forest, an old red pine ( Pinus resinosa Ait.) forest, a mature red spruce and red maple forest, an old-growth white spruce and balsam fir forest, and a conifer forest with black spruce ( Picea mariana (Mill.) B.S.P.), balsam fir, and eastern white cedar. Adults were taken from fleshy fungi, gilled mushrooms, decaying fleshy fungi, decaying mushrooms, fleshy polypore fungi on dead standing American beech, small stalked polypore fungi on forest floor, Polyporus varius Fr. on rotten logs and standing dead sugar maples, under bark of sugar maple, and from leaf litter. Several adults were captured in Lindgren funnel traps. Adults were collected during May, June, July, August, and September.
