Coniferous and mixed forests and swamps, especially under cedar, but also in beech-maple, aspen, and other forests; and less commonly in bogs and tamarack swamps; often in deep shade. Very local southward.

Usually easily recognized by its small stature (though rarely as tall as 28 cm), yellow or greenish yellow color, and (usually) unspotted lip (but see Corallorhiza maculata forma flavida).
