Foliose Lichen thallus (composite)

There is no real foliose lichen that has all of these features, but all of those lichens will have some of them.
Lobes can be narrow or wide, they give the lichen its "leafy" appearance (thus the term "foliose").
Cilia are thin appendages that are found on the lobe margins of some lichens.
Rhizines are not roots, they are outgrowths of hyphae that attach the lichen to its substrate (rocks, bark, etc.) These structures do not take up water or nutrients like plant roots.
Sorelia and Isidia are vegetative reproductive bodies that contain both fungi and algae, they can grow a new lichen if the small pieces end up in a good growing location.
Apothecia are flat or cup-like reproductive structures.
