You must be ethical when you collect. In order to identify lichen to species, lichenologists use common household chemicals and some not-so-common chemicals to test the color reaction of the unique compounds found in the structure of the lichen, as well as using a lichen key to distinguish between species. 1400 Independence Ave., SW It is hoped that this guide will aid in the identification of some common Lichens grow slowly and take a long time to cover an area. Each lichen thallus is a complete microscopic world with unique characteristics separating it from the other lichens. Lichens are classified based on the fungus and fungal features. Some lichens are combinations of squamulose and fruticose such as species of Cladonia (see Figures 4A, 4B).. Never take more than you need, and never take the entire population in the area.
