Phoradendron leucarpum is a species of mistletoe in the Viscaceae family which is native to the United States and Mexico.

[6] Ingesting the berries can cause "stomach and intestinal irritation with diarrhea, lowered blood pressure, and slow pulse".

[7] Phoradendron leucarpum is used in North America as a surrogate for the similar European mistletoe Viscum album, in Christmas decoration and associated traditions (such as "kissing under the mistletoe"), as well as in rituals by modern druids.

[9] Over 60 species of trees are hosts to P. leucarpum, especially trees in the genera of Acer (maple), Fraxinus (ash), Juglans (walnuts), Nyssa, Platanus (plane trees), Populus (poplars), Quercus (oaks), Salix (willows), and Ulmus (elms).

[2] While the sticky substance covering the fruits is toxic to humans, it is a favorite of some birds.
