Spiranthes casei, or Case's lady's tresses, is a species of orchid native to the northeastern United States and Canada.

The petals and sepals have an ivory to yellowish white or greenish cream color.

[3] Spiranthes casei is very closely related to and looks similar to Spiranthes ochroleuca but has smaller flowers, the dorsal (top) sepal and tips of the side petals are not recurved, and they have a comparatively reduced labellum.

[4] Spiranthes casei has been found in Maine, Michigan, Minnesota, New Hampshire, New York, Pennsylvania, Vermont and Wisconsin in the US and in Nova Scotia, Ontario and Quebec in Canada.

[5] It grows in forest, shrubland and grassland, mostly restricted to the lichen and bracken barrens of the Great Lakes Basin and the Canadian maritime provinces.
