Vulpicida is a genus of lichenized fungi in the family Parmeliaceae. Circumscribed in 1993 to contain species formerly placed in Cetraria, the genus is widespread in Arctic to northern temperate regions, and contains six species. The genus is characterized by the presence of the secondary metabolites pulvinic acid and vulpinic acid, compounds that when combined with usnic acid, give the species their characteristic yellow and green colors.

Vulpicida pinastri, the powdered sunshine, is a species of foliose lichen in the family Parmeliaceae. The lichen has a greenish-yellow thallus and dorsiventral lobes. It grows on conifers and Betula in North America and Eurasia. It is the only sorediate species in the genus and is distinguished by the bright-yellow marginal soralia. The lichen, originally described by Italian naturalist Giovanni Antonio Scopoli in 1772, was transferred to the newly circumscribed genus Vulpicida by Jan-Eric Mattson and Ming-Jou Lai in 1993.

Vulpicida juniperinus is a species of lichen found in the Northern Hemisphere, commonly known as rock sunshine lichen or yellow rock lichen. This species is characterized by its bright yellow, coral-like growth form on exposed ground, often in Arctic or alpine areas. Previously thought to be three distinct species, V. juniperinus is now thought of as a single species or a species complex, composed of what used to be V. juniperinus, V. tilesii, and V. tubulosis.

Vulpicida canadensis, the brown-eyed sunshine lichen, is a species of foliose lichen in the family Parmeliaceae. It is endemic to northwestern North America where it grows as an epiphyte on the bark and wood of conifer trees.
