LICHEN THAT THRIVE BECAUSE OF AMMONIA
Due to a decrease of ammonia in the environment Vingermosachtigen and Dooiermosachtigen. start to disappear.
The historical change from an ammonia-rich environment to a clean environment is often remarkably visible.
For example, in the image Groot Dooiermos is breaking down from its center (see the empty black spot in the middle), making a place for other species that prefer clean environments, such as Gewoon eikenmos (see grey bush).

A: Teloschistales & Camdelariales
Dooiermosachtigen & Geelkorstachtigen
Four common ''yellow'' species are:
Candelaria concolor
Vals dooiermos
A small, highly branched, green-yellow, leaf-like species.
Xanthoria parietina
Groot dooiermos
A large, yellow, leaf-like species with conspicuous orange fruiting bodies.
Candelariella reflexa
Poedergeelkorst
A bright yellow, crust-like species that often grows in wide, vertical bands along the trunk.
Xanthoria calcicola
Oranje dooiermos
Not to be confused with Groot Dooiermos, but not quite. This specie is more orange, flattened, less apthecia, iand sidia are almost always present.
B: Caliciales
Vingermosachtigen
Three common ''grey'' species that are commonly found are:
Physcia adscendes
Kapjesvingermos
A small, gray, leaf-like species with roots and upright, lighter-colored caps.
Physcia tenella
Heksenvingermos
A small, gray, leaf-like species with small rootlets at the edges. The tips are powdery.
Phaeophyscia orbicularis
Rond schaduwmos
A dark gray, leaf-like species that forms powdery heaps in the middle of the rosettes.
