Parasitic on numerous hosts; those documented in Michigan include species of Mentha, Euthamia, Symphyotrichum, Stachys, Ceanothus, Amphicarpaea, Solidago, Bidens, Monarda, Symphoricarpos, and Corylus.

In its distinctive ± fleshy papillate perianth and thickened summit of the fruit, this species resembles C. indecora, from which it differs in its 4-parted (though occasionally 5-parted) smaller flowers (ca. 2 mm long before enlargement of fruit). Frequently at least some of the pedicels equal or exceed the flowers (not fruit) in length, giving the inflorescence a more open aspect than in some other species.
