It does look tastyβ¦but only a very small number of lichens are (occasionally) eaten by humans...and even those generally taste like crap:) Even caribou mainly stick to 3 or 4 of these matt-forming, fluffy white Cladonia species out of the 20,000 or so lichen species that are known

Photo of an orange lichen growing on the white bark of a birch tree. The lichen looks like a roundish mound of orange discs which are the apothecia (spore producing structures).
A Xanthoria/Sunburst lichen, I think.
NWT, Canada. The orange lichen is about 3cm wide. #lichen #fungi #fungifriends

Thanks! lichens actually donβt hurt trees at all. It can seem like lichens are hurting trees because the number of lichens on a tree increases with tree age. So, by the time trees are quite old and dying (old age) they are often covered in lichenβ¦leaving the impression that lichens are the cause.

lichens are composite species consisting of a fungus and a photosynthetic partner - either an alga, a Cyanobacterium or both.

Thanks! Like flowers, the orange parts are reproductive structures. Theyβre called apothecia and they are the structures that produce spores.
