Common names for lichens may contain the word moss (e.g., "reindeer moss", "Iceland moss"), and lichens may superficially look like and grow with mosses, but they are not closely related to mosses or any plant. [6]: 3 Lichens do not have roots that absorb water and nutrients as plants do, [15]: 2 but like plants, they produce their own ...
Usnea filipendula – one of about 20,000 described species of lichen. The following outline provides an overview of and topical guide to lichens.. Lichen – composite organism made up of multiple species – a fungal partner, one or more photosynthetic partners, which can be either green algae or cyanobacteria, and, in at least 52 genera of lichens, a yeast.

Warmer temperatures favor the growth of larger plants, causing lichens, the reindeer’s primary food source, to become scarce. Lichens are a symbiotic combination of a fungus and a ...
Thallophyta is a division of the plant kingdom including primitive forms of plant life showing a simple plant body. Including unicellular to large algae, fungi, lichens. [5] The first ten phyla are referred to as thallophytes. They are simple plants without roots stems or leaves. [6] They are non-embryophyta. These plants grow mainly in water.
Barklice are also found on trees, where they eat algae and lichen. Most booklice measure 0.03 – 0.07 inches long. The wingless species can be easily mistaken for bed bugs or lice.
A cyanolichen is a lichen with a cyanobacterium as its main photosynthetic component . [12] Many cyanolichens are small and black, and have limestone as the substrate. Another cyanolichen group, the jelly lichens (e.g., from the genera Collema or Leptogium) are large and foliose (e.g., species of Peltigera, Lobaria, and Degelia. These lichen ...
Lichens are composite organisms, consisting of a fungal mycobiont and one or more photosynthetic partners (either green algae or cyanobacteria, or both). One or more ...
Lichens are known in which there is one fungus associated with two or even three algal species. Rarely, the reverse can occur, and two or more fungal species can interact to form the same lichen. [12] Both the lichen and the fungus partner bear the same scientific name, and the lichens are being integrated into the classification schemes for fungi.
