vary – sometimes significantly – which can lead to some lobes being overgrown by others. When this happens, the overgrown lobes stop growing and are ultimately swallowed up by the expanding lichen. As with other crustose lichens, placodioid lichens have a cortex on their upper surface, but not their lower one. This allows them to be distinguished from foliose lichens, which can be similar in appearance but have both an upper and a lower cortex. Crustose lichens may be both placodioid and areolate, as in, for example,
624: 706: 887: 209:; lichens with similar growth forms are not necessarily related, and some of those which are related do not have similar growth forms. Not every species can be easily categorized. Some show characteristics of two growth forms, and different authors may place such species in different groups. In general, a particular species shows same overall growth form wherever it is found, but this is not always the case. Traditionally, crustose, foliose and fruticose are considered to be the three main forms. 1493: 690: 846:, they are completely unattached to a substrate. Unlike a foliose lichen, a fruticose lichen does not have a distinct upper and lower surface. Instead, a cortex covers its entire surface, and the photobiont layer lies just below this, on all sides of the lichen's branches. The centre of a fruticose lichen's branches varies depending on the genus involved. In most, the centre is hollow. However, lichens in the genus 229:. This layer, which is usually dark, generally grows faster than the thallus which rides above it. This growth form is an adaptation which allows the lichen to cope with alternating periods of wet and dry. During wet periods, the lichen can absorb water, its tissues can swell, and the cracks close. The term "areolate" is derived from the 185:
need to survive. The yeast (where present) appears to help ward off microbes and potential predators through the production of various chemicals. Thallus types have evolved to provide the lichen's photobiont with optimal levels of light, water, and carbon dioxide, with different environmental conditions favouring different forms.
767:, typically located near the lichen's centre. Lichens with this structure are called "umbilicate". In general, medium to large epiphytic foliose lichens are moderately sensitive to air pollution, while smaller or ground-dwelling foliose lichens are more tolerant. The term "foliose" derives from the Latin word 576:
A crustose lichen, as its name suggests, is crust-like and two-dimensional, closely and completely bound at nearly all points to the substrate on which it grows. It typically cannot be removed from the substrate without at least partial destruction of one or the other. Some crustose lichens are thick

A placodioid lichen is a form of crustose lichen with lobed margins. These lobed edges, which radiate from the central part of the lichen, are its only growing sections; the central part of the lichen typically contains reproductive structures and does not expand. The growth rates of these lobes can

A fruticose lichen is typically shrubby or coral-like in appearance, though some are hair-like or strap-like instead. Some grow upright while others hang. They attach to the substrate only at a single point at their base (or at most a very few points), and can be easily removed. Sometimes, as in the

that are generally not firmly bonded to the substrate on which it grows. It typically has distinct upper and lower surfaces, each of which is typically covered with a cortex; some, however, lack a lower cortex. The photobiont layer lies just below the upper cortex. Where present, the lower cortex is

A gelatinous lichen, also widely known as a "jelly lichen", is one with a cyanobacterial species ("blue-green alga") as the principal photobiont. Chains of the photobiont, rather than fungal hyphae, make up the bulk of the thallus, which is unlayered (and undifferentiated) as a result. Such lichens

Unlike most of the other forms detailed here (the exception being some byssoid lichens), a filamentous lichen's morphology is determined by its algal partner rather than its fungal partner. A thin layer of fungal hyphae surrounds an algal chain, resulting in a thread-like or hair-like structure.
418:, is typically brown or black, and spores are dispersed passively from it. Most calicioid lichens are crustose with tiny stalked fruiting bodies. However, because the fundamental characteristic of a calicioid lichen is the presence of a mazaedium rather than a stalked fruiting body, a handful of 1012:
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. Morphologically, it is the

In addition to the above forms, lichenologists have named a handful of informal growth forms for their resemblance to members of particular genera. Each of these is a subset of one of the growth forms described above. For an indication of what they look like, see the gallery below.

lack a cortex. Despite this lack of internal structure, gelatinous lichens usually have external growth forms that resemble those of fungal-dominated lichens. Gelatinous lichens are particularly common in areas with erratic rainfall or periodic inundation (such as

In addition to these more formalised, traditional growth types, there are a handful of informal types named for their resemblance to the lichens of specific 759:.
