Collection and habitat data.

In New Brunswick, Gyrophaena nanoides was found in various deciduous and coniferous forest types, including hardwood forests with suga r maple ( Acer saccharum Marsh.), American beech, and white ash ( Fraxinus americana L.), an old red oak forest, a mixed forest with eastern hemlock ( Tsuga canadensis (L.) Carr.), mixed forests, red spruce forests, a black spruce forest, and a black spruce, balsam fir and eastern white cedar forest. Most adults were collected from fresh (not decaying) gilled mushrooms, including a Russula sp. Some specimens were collected from a stalked polypore fungus on forest floor, a Boletus sp., and a Pleurotus sp. on a log. Little was previously known about the habitat associations and bionomics of this species. Adults were collected during August and September.
