relationship. The alga supplies nutrients by photosynthesis, while the fungus shades the alga from excessive sunlight and supplies water by absorbing water vapor from the air. Lichens often live on rocks and tree bark and can thrive in extreme environments, such as mountaintops and the polar ...
Others, however, cited the seemingly healthy and long-lasting nature of lichens as evidence of mutualism. As we report here, our observations of artificial syntheses of the mycobiont Cladonia cristatella (‘British soldiers’) with different algae suggest that the relationship in this lichen is ...
Lichen is an evolutionarily successful mutualism of an alga (cyanobacteria) and a fungal species that supports different microorganisms’ growth. The symbiotic associations between an alga and a fungus species create an environment within the lichen thallus body. Microbes such as algae, fungi, and end...

An organism that consists of a fungus and an alga living together in a symbiotic relationship. The alga supplies nutrients by photosynthesis, while the fungus shades the alga from excessive sunlight and supplies water by absorbing water vapor from the air. Lichens often live on rocks and tree ba...
This little thing of beauty, called jelly lichen, consists of Nostoc cyanobacteria too, but in combination with a Leptogium fungus whose hyphae have lent pattern, structure and stability to the raw photosynthesising power of the cyanobacteria. The form emerges from the relationship between the ...
The fungus can not survive with out this energy source so we have the example of a classic obligatory symbiotic relationship. This also explains why lichens can be found growing in the middle of a rock in the middle of nowhere. In our photo, the gray spreading fans are the thali and ...

Later, de Bary (1879) proposed that the relationship between the two was mutualistic. Over the course of the following century, scientists and philosophers have debated whether the interactions between fungus and alga reflect mutualism or parasitism, slavery, farming, or commensalism (Richardson, 1999...
