About Lichens - US Forest Service
Lichens are a complex life form that is a symbiotic partnership of two separate organisms, a fungus and an alga. The dominant partner is the fungus, which gives the lichen the majority of its characteristics, from its thallus shape to its fruiting bodies. The alga can be either a green alga or a blue-green alga, otherwise known as cyanobacteria.

2024年4月21日 · A lichen is a combination of two organisms, a green alga or cyanobacterium and an ascomycete fungus, living in a symbiotic relationship. Whereas algae normally grow only in aquatic or extremely moist environments, lichens can potentially be found on almost any surface (especially rocks) or as epiphytes (meaning that they grow on other plants).
What is a lichen? - WSL
A lichen is a symbiotic organism, i.e. one that is made up of two different species that both benefit from each other. The basis of the lichen organism is a fungus, the mycobiont. In most cases this is a ascomycete, in rarer cases it is a basidiomycete.
