Candelariella antennaria, or the pussytoes eggyolk lichen, [2] is a lichen commonly distributed in North America, and has been observed in South America, Asia, Australia, and Europe. [3] [4] [5] [6] It is characterized by its gray thallus and bright yellow apothecia, as well as its very small size. [3]
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]
Candelariella antennaria is most often found on tree bark of deciduous trees. [3]
