2008) and other fungal references and databases. This classification is used in theĭictionary of the Fungi (Kirk et al. (2007) published a comprehensive classification of the Kingdom Fungi, the result of collaboration among many fungal taxonomists.
A group of parasitic organisms called Microsporidia that live inside the cells of animals are also now considered to belong in the fungal kingdom (Fig. Glomeromycota, a group of fungi once placed in Zygomycota that form an association with the roots of most plants (Fig. Recent studies have provided support for the recognition of additional phyla, such as Open most introductory mycology books and you'll see that there are four main groups (phyla) of true fungi- Ascomycota, Let's briefly consider the major groups in Kingdom Fungi-they will be described in greater detail later. Kingdom Fungi (Eumycota), the Oomycetes, and the slime molds (Fig. We also recognize that organisms traditionally studied as "fungi" belong to three very different unrelated groups: the true fungi in Fungi may not be our next of kin, but they are more closely related to animals than they are to plants. Tree of Life Project show that fungi and animals both belong to the group Opisthokonta (Fig. In fact, recent taxonomic treatments such as the We now know that fungi are not primitive at all. Some fungi infect a living host, but kill host cells in order to obtain their nutrients these are calledįungi were once considered to be primitive members of the plant kingdom, just slightly more advanced than bacteria. Some fungi obtain their nutrients from a living host (plant or animal) and are calledīiotrophs others obtain their nutrients from dead plants or animals and are called Heterotrophs and, like animals, obtain their carbon and energy from other organisms. Most fungi reproduce by spores and have a body (thallus) composed of microscopic tubular cells called hyphae. Washington State University, Kansas State University, and Georgia Military College What is a fungus?Ī fungus is a eukaryote that digests food externally and absorbs nutrients directly through its cell walls.
