Collection and habitat data
This is a hygrophilous species in both Europe and North America and is usually found in marshes and bogs in moss (especially sphagnum) and debris (Campbell 1991[1]). In New Brunswick, this species was found in various wetland habitats, including a forested black spruce (Picea mariana (Mill.) B.S.P.) bog, an eastern white cedar swamp, sedge (Carex) fens and marshes, freshwater marshes, stream margins, the margin of a vernal pond, and in an abandoned North American beaver Castor canadensis Kuhl) lodge occupied by muskrats (Ondatra zibethicus L.). Adults occurred in moist leaves, sphagnum, litter, and moss, in Carex hummocks, and in debris in the roof of a beaver lodge. In New Brunswick, this species was collected during March, April, May, and June.
Distribution in Canada and Alaska
ON, QC, NB (Campbell 1991[1]). Campbell (1991)[1] considered the distribution and habitat of this species in the Nearctic region unusual for a Holarctic species because of the specialized habitat preferences (found in sphagnum and debris in marshes and bogs) and pattern of distribution (restricted to Ottawa Valley of Ontario and Quebec). He suggested that the species may have been overlooked by most collectors and may actually have a broader distribution in North America than the records indicate. Klimaszewski et al. (2010)[2] considered Tachyporus transversalis Gravenhorst as an adventive Palaearctic species.
