Unformatted text preview: foliose lichens have flat, leafy structures like lettuce, while crustose lichens are crusts-like structure, and fruticose are resemble miniature upright shrubs or hang down in festoons from branches. Lichens are commonly found on soil, rock or tree bark. However, recently, biologists have found the third contribution of another fungus called basidiomycete yeast through researching the variation between two species of lichens consisting of the same fungus and alga. Thereafter, they realized the amount of basidiomycete yeast’s genes is higher in the yellow lichen having vulpinic acid. In addition, the basidiomycete yeast has the function in variating the species which means structure than the environment. This new discovery changes the traditional view of lichens that basidiomycete yeast will be an effective assistant of fungus to make a lichen with alga....
