A less common cause of irritation is genital lichen planus, another inflammatory disorder. A severe variant of this is vulvovaginal-gingival syndrome, which can lead to narrowing of the vagina, [69] or vulva destruction. [70] Many types of infection and other diseases including some cancers may cause irritation. [71] [72]
Lichen growth forms are used to group lichens by "vegetative" thallus types, and forms of "non-vegetative" reproductive parts. Some lichen thalli have the aspect of leaves (foliose lichens); others cover the substrate like a crust (crustose lichens) (illustration, right), others such as the genus Ramalina adopt shrubby forms (fruticose lichens ...

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.
