DEF

A lichen with a large thallus that is not considered crustose.

CONT

A macrolichen is a lichen that is either bush-like or leafy; all other lichens are termed microlichens. ... Here, "macro" and "micro" do not refer to size, but to the growth form.

CONT

CONT

Les lichénologues distinguent parfois les «macrolichens» (forme des lichens squamuleux, foliacés ou fruticuleux), des «microlichens» (lichens crustacés granuleux, verruqueux, pulvérulents ou lépreux) [...]; les préfixes «macro» et «micro» ne se réfèrent donc pas ici à la taille du lichen, mais à la hauteur de son thalle et à la forme de croissance du lichen.

CONT

Les espèces les plus sensibles à la pollution de l'air sont les «macrolichens», comme les Bryoria, Parmotrema et Usnea.
