Fungus

Have you seen something like this picture in your yard? If so, you were looking at fungus, and they are common. Many of them are known as mushroom.

According to Wikipedia, Fungi are a kingdom of eukaryotic organisms. The fungi are heterotrophic organisms characterized by a chitinous cell wall. Some fungal species also grow as single cells. Sexual and asexual reproduction is commonly via spores, often produced on specialized structures or in fruiting bodies. Some fungal species have lost the ability to form specialized reproductive structures, and propagate solely by vegetative growth.

Yeasts, molds, and mushrooms are examples of fungi. The fungi are a monophyletic group that is phylogenetically clearly distinct from the morphologically similar slime molds (myxomycetes) and water molds (oomycetes). The fungi are more closely related to animals than plants, yet the discipline of biology devoted to the study of fungi, known as mycology, often falls under a branch of botany. Go here to learn more.
