A fruticose lichen may have flattened "branches", appearing similar to a foliose lichen, but the underside of a leaf-like structure on a fruticose lichen is the same color as the top side. The leaf-like lobes of a foliose lichen may branch, giving the appearance of a fruticose lichen, but the underside will be a different color from the top side.
Lichen fragments can be dispersed from animals at longer distances, but this is not the main method used in reproduction and regeneration. [3] Lichens reproduce sexually in one of two ways, heterothally or homothally , yet the obligate lifestyle of Cladonia species and many others makes studying the sexual reproductive cycle nearly impossible ...
A leprose lichen, which is typically considered to be a form of crustose lichen, is one with a powdery or dust-like appearance. Its undifferentiated thallus is an irregular mix of fungal hyphae and scattered photobiont cells, lacking a cortex or any definable layers. [6] [47] Morphologically, it is the simplest growth form.
