The Fungi, are well-known as mushrooms, toadstools, molds, and morels. Along with bacteria, fungi are the fundamental decomposers in nature, and the cause of many plant diseases, pneumonia, and ringworm. Humans use fungi for production of alcohol, cheese, penicillin, cyclosporin, as well as culinary delicacies. They are of great importance to plants because they form important symbiotic relationships with plant roots, called mycorrhizae.
They are organisms that may appear plant-like, but are more closely related to animals. They belong to a group called the opisthokonts, sharing similarities in how their sex cells are constructed. The body of a fungus has a mass of thread-like strands, called hyphae or mycelium. Some have an algae construction (thalloid). All fungi have chitin in their cells walls (similar to animals)
Fungi are filamentous in construction, with strands called hyphae
A mass of hyphae ("white fuzz") is called mycelium
Chitin found in cell walls is a synapomorphy for the fungus clade
└Opisthokonta: Fungi and Animals
└Holomycota
└Eumycota
├Chytrids(Chytridiomycota): Aquatic fungi
├Molds (Mucoromycota): Bread molds; fruit molds
├Arbuscular mycorrhizae (Glomeromycetes)
├Club fungi (Basidiomycota): Mushrooms, Toadstools, Shelf fungi, etc.
├Sac fungi (Ascomycota): Morels, Truffles
└Incertae Sedis - Unclassified
Haplontic life cycle in most (except chytrids)
Feeding phase is haploid
During reproduction, strands of different organisms combine to form a larger reproductive structure, such as a mushroom
The cells from each organism fuse together, but the nuclei do not fuse
This condition is called dikaryotic, in which each cell has two nuclei
When the structure is mature, these nuclei fuse together to create the only diploid cell in the lifecycle
This diploid cell then goes through meiosis to produce haploid spores
