Fungi & Lichens

A fungus is a member of the kingdom Fungi - a grouping of some 80,000 organisms that range from single-celled yeasts to mushrooms and molds to large slabs of bracket fungus growing up the sides of trees. Many fungi live freely in soil or water and many more engage in parasitic or symbiotic relationship with plants and animals. Most species are composed of strands of cells called hyphae that combine to fungal body or mass known as a mycelium.
