Fruticose or ‘shrubby’ lichens differ from other forms of lichen because their bushy form is attached to the substrate only at the base of the lichen. A continuous algal layer grows around the circumference of the branches of the lichen. [3] Many fruticose lichens have fine, round, hair-like structures and are loosely attached to rocks and ...
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] The term "filamentous" is derived from the Latin filamentum, meaning "filament", itself derived from the Latin filare, meaning "to spin", from filum, meaning "thread". [33]
Letharia vulpina, commonly known as the wolf lichen (although the species name vulpina, from vulpine relates to the fox), is a fruticose lichenized species of fungus in the family Parmeliaceae. It is bright yellow-green, shrubby and highly branched, and grows on the bark of living and dead conifers in parts of western and continental Europe and ...
But sometimes the parts of a lichen species common name are common names of other lichen genera. For example, Psilolechia lucida, in the genus Psilolechia, is commonly called "sulphur dust lichen". [1] [2] But "sulphur lichen" refers to the genus Fulgensia, and "dust lichen" refers either to the genus Chrysothrix or the genus Lepraria. [1] [3 ...
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 ...
Other common growth forms are crustose, crustlike lichens that grow tight against, even into, the substrate, and fruticose lichens, which grow as free-standing branches like tiny trees.
Cladonia stygia, commonly known as the blackâfooted reindeer lichen, is a species of fruticose lichen in the family Cladoniaceae. [2] It is distributed across boreal , arctic and temperate regions of the Northern Hemisphere.
The Teloschistes capensis is a type of fruticose, or shrubby, lichen, typically growing upright and ranging from 3 to 8 cm in height.Its densely branched structure features main branches about 0.5 mm in diameter, which can be either circular or angularly rounded in cross-section.
