Species of lichen

Elixjohnia jackelixii is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is found in Australia and New Zealand. The lichen is characterised by its unique multilayered appearance with outer sterile rings that are brownish or greenish-yellow and inner areoles that are whitish, yellowish, or greyish, often cracked to reveal the medulla underneath. Its fruiting bodies, or apothecia, are typically attached directly to the thallus and vary in colour and shape.
