Catolechia wahlenbergii

Wahlenberg's goblin lights lichen

"Goblin lights lichen core" could totally be a spotify playlist. Have you ever made a playlist based off of a lichen? Well consider this your sign to do so. This little beauty has a squamulose or crustose-placodioid thallus that grows in thick, bright yellow-green patches on acidic, humus-rich soil and bryophytes (often in the cracks of siliceous rocks). It is wrinkled and puckered in texture, and the upper surface often has brown patches and tiny yellow crystals. It has a black lower surface and black prothallus, and is attached to the substrate by numerous black rhizoids. It produces round or crenulate apothecia which are black, sessile, and convex. C. wahlenbergii can be found in humid, arctic-alpine habitats in the northern hemisphere.
