Wild About Illinois Fungi!

The body of fungi (mycelium) is made up of strands called mycelia. The mycelium grows within the soil, a dead tree or other object and is rarely seen. The fruiting body that produces spores is generally present for only a short period of time but is the most familiar part of the fungus to people.

Fungi may be found statewide in Illinois. They grow in nearly all Illinois habitats. Unlike plants, fungi do not have roots, stems, leaves, flowers or seeds. They must absorb nutrients and water from the objects they grow in. Spore production occurs when conditions are favorable, generally with warm temperatures and ample moisture. The spores produced provide a means of reproduction, dispersal and survival in poor conditions.

Species Gallery

​Kingdom: Fungi - The fungi are multicellular eukaryotes (cells with a nucleus) that obtain food by absorbing nutrients from their surroundings. Cell walls are present and in most species they are composed of chitin. The body is made of mycelia. Spores are produced.
Phylum: Basidiomycota - The basidiomycete fungi include the mushrooms, bracket fungi and smuts. They are often called club fungi because most of them produce spores at the tip of the club-shaped structures.
