It is characterized by its gray thallus and bright yellow apothecia, as well as its very small size.
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. The disc may test K negative, or reddish. All other spot tests are negative. The thallus is colored gray and scattered, but not granular. The thallus is composed of non-gelatinized and thin-walled hyphae that do not form stipes. The lichen is small, which makes it hard to spot.
Habitat Candelariella antennaria is most often found on tree bark of deciduous trees.
