    Crustose lichens on a wall Growth of crustose lichen on a tree trunk. Crustose lichens are lichens that form a crust which strongly adheres to the substrate (soil, rock, tree bark, etc.), making separation from the substrate impossible without destruction. [1] The basic structure of crustose lichens consists of a cortex layer, an algal layer ...

    Many lichens grow close to the surface of rocks, tree trunks, and other substrata, and are referred to as crustose lichens.Crustose organisms can be detrimental to engineered structures when found on buildings, coastal structures, and ships.

    Tillandsia bourgaei growing on an oak tree in Mexico. An epiphyte is a plant or plant-like organism that grows on the surface of another plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phorophytes.

    They are often epiphytic, growing on trees in forested areas, but are also common in some alpine zones. [30] Lichenologists tend to consider filamentous lichens to be a type of fruticose lichen. [31] This is an uncommon growth form, found in only a handful of genera. [32]

    Verseghya thysanophora is commonly found growing on the trunks of deciduous trees, especially Acer saccharum and Thuja occidentalis, as well as occasionally on shaded siliceous rocks. This lichen is typically found in mature maple forests, and is most often fertile on trees that are located near streams.

    A prominent example is the alga Trentepohlia which forms orange-coloured populations on tree trunks and suitable rock faces. Lichen propagules typically contain cells from both partners, although the fungal components of so-called "fringe species" rely instead on algal cells dispersed by the “core species.” [5]
