Monotropa hypopithys of Michigan Flora.

Coniferous or deciduous forests or even conifer swamps.

Specimens in fruit might be mistaken for small ones of Pterospora andromedea; besides lacking the clammy pubescence of that species, the style is 2.4–5 mm long, hirsute, and noticeable on the fruit. In Pterospora, the style is ca. 2 mm long or less, glabrous, and nearly or quite concealed by the expanding fruit. Neyland & Hennigan (2004) present clear evidence supporting the recognition of Hypopitys.

Plants are mostly yellowish to pale cream, the stem sometimes lightly tinged with pinkish. Distinctly red plants, perhaps mostly confined to southertn Michigan (though few of our collections have color notes), are sometimes segregated as Hypopitys lanuginosa (Michx.) Nutt.
