Characteristics

Candelariella antennaria is a crustose lichen best characterized by its yellow apothecia, which make up the majority of the visible lichen. The apothecial disc is a lemon-yellow or orange-yellow, flat, and not exceeding 1 mm in diameter.[3] The disc may test K negative, or reddish.[3] All other spot tests are negative.[3] The thallus is colored gray and scattered, but not granular.[5] The thallus is composed of non-gelatinized and thin-walled hyphae that do not form stipes.[6] The lichen is small, which makes it hard to spot.[7]

Habitat

Candelariella antennaria is most often found on tree bark of deciduous trees.[3]
