Hymenophyllum tunbrigense is found on damp, shady rocks in southern Skye it is much less common than H. wilsonii and the species is at its most northern limits in Britain in VC104. It is confined to altitudes below 90m and above this altitude any filmy fern found will almost certainly be H. wilsonii. In Rodwell (ed.) (1991) it occurs in the W17a community.

H. tunbrigense and wilsonii occasionally grow together as a mixed community and then the toothed lip of the indusium in H. tunbrigense is the best way of distinguishing the two species rather than relying on the colour of the leaves.
