FungiFungal biofilmMicrobial developmentLichens are traditionally defined as a symbiotic relationship between fungi and algae and/or cyanobacteria. This union forms a unique structure called the thallus, which attaches to surfaces such as rocks and tree bark. Recent reports challenge the view that ...
1.(Plants) an organism that is formed by the symbiotic association of a fungus and an alga or cyanobacterium and occurs as crusty patches or bushy growths on tree trunks, bare ground, etc. Lichens are now classified as a phylum of fungi (Mycophycophyta) ...
Lichen symbiosis Lichens are not single organisms, rather they are a symbiotic relationship between a fungus and an algae or cyanobacteria. The relationship works because each element helps the other. The fungi in lichens need sugars or carbohydrates as a food so...
each one is a symbiotic combination of an alga and a fungus.The algae capture the sun's energy by photosynthesis and store it in organic molecules.The fungi absorb moisture and mineral salts from the rocks, passing these on in waste products that nourish algae.It is significant that the earl...
. Fungi take more dominant role and cultivate photosynthesizing algae for food and in return provide a shady, moist, vitamin-rich environment, so sci- entists classify lichens based on their associated fungal species. Whether the fungi were harvesting algae or cyanobacteria, the symbiotic modus ...
and Streptomycetaceae were more predominant in homogenate samples, thus indicating a putatively closer association of these taxa. Whereas presence of Pseudonocardiaceae strains in only one of the wash samples might indicate an episymbiotic association or a more occasional relationship. ...
In addition, to test the sequence conservation among the putative SQSs of the two clans and of the SQSs of these clans with those of non-lichenized fungi (Aspergillussp.,Candida albicans), and the flagellated protozoan species,Trypanosoma cruzi, we aligned the abovementioned sequences using GENE...
while others associate with a different algal partner, termed algal switching22, or host multiple algal types (coexistence). Thus, questions related to the strategies used to acquire phycobionts in lichenicolous lichens remain open. Crustose gypsum lichenized fungi and associated lichenicolous lichens...

the algae—or specializedblue-green algaecalled cyanobacteria—provide food and the fungi wraps around it creating a shelter. "The question of when lichens evolved and how many times fungi evolved the ability to form symbiotic relationships with algae has been a bit contentious in the past," says...
