The Digestive and Endocrine System Game

The Ascomycota split from the Basidiomycota approximately million years ago, followed by an increase in fungal diversity throughout the Paleozoic. Most yeasts and "asco-molds" are thought to have evolved in approximately the last million years. While most plants and vertebrates appear to have been described, most fungi have yet to be discovered or named. The edition of the Dictionary of Fungi counts , described species about , in the Eumycota but notes that there may be approximately 1.

Elias Fries — , often regarded as the "father of mycology," classified fungi based primarily on spore print color and sporocarp appearance. Friesian-based nomenclature, reflecting similarity of form phenetic rather than genetic relationships, is still used in many field guides.

Now, however, taxonomists are integrating molecular and morphological characters to develop natural classifications that more adequately reflect evolutionary relationships. Realizing that fungal taxonomy and nomenclature will remain somewhat fluid until new species and data are analyzed and integrated, most mycologists generally accept the classification below. The fact that chytrids alone among the Eumycota produce motile zoospores explains why their phylum is sometimes assigned with the flagellate oomycetes to kingdom Chromista.

Chytrids possess posteriorly uniflagellate spores, mitochondria with flattened cristae, and cell walls composed of glucan and chitin. Among the simplest and smallest fungi, they live as saprobes in water and damp organic-rich habitats, or as parasites on invertebrates, plants, and other fungi. The so-called "frog chytrids" such as Batrachochytrium dendrobatidis are implicated in the current worldwide decline of amphibian species.

Other chytrids are host-specific "rumen fungi" such as Piromyces communis that thrive in anaerobic conditions in the guts of herbivores, such as cattle and sheep. There are five orders and about species of chytrids recognized thus far. Unicellular members of the order Chytridiales lack a mycelial stage and consist of a central body with a few rudimentary appendages haustoria that attach to and invade the host tissue.

Chytrid thalli may be either haploid or diploid, and some, like the aquatic chytrid Allomyces, exhibit an isomorphic alternation of generations with similar appearing sexual and asexual zoospores.

The chytrids and this phylum are assigned the two "bottom" branches of the fungal evolutionary tree. There are more than 1, species in two classes Trichomycetes, Zygomycetes and ten orders, representing a diverse assemblage of saprobes, soil fungi, obligate insect and fungal parasites, and mycorrhizal formers. Common representatives of the saprobic order Mucorales include the dung-inhabiting "cap-thrower" Pilobolus , the black bread mold Rhizopus stolonifera , and Phycomyces blakesleeanus, sometimes referred to as the "body in the basement" because of the rapid growth of long, hairlike sporangiophores over a substrate under the right conditions.

Zygomycota are characterized by large, thick-walled, coenocytic zygospores and hyphae with relatively thin walls composed of chitin and chitosan. Both asexual sporangiospores and sexual zygospores germinate into haploid mycelia, with the hyphae functioning as gametangia during the sexual stage.

In Rhizopus, for instance, close proximity of two hyphal strands of different mating types chemically triggers each to grow branches toward the other to form septate suspensor cells and gametangia. Eventual fusion produces a diploid zygosporangium that undergoes meiosis to become a thick-walled zygospore with large numbers of haploid nuclei.

In addition to most lichens and so-called "imperfect fungi," about 33, species of unicellular yeasts, green and black molds, powdery mildews, morels, cup fungi, and ascotruffles "true" truffles belong to this phylum.

The phylum is characterized by ascospores produced within a saclike sporangium called an ascus. Mycelia more complex than Zygomycota mycelia are composed of septate hyphae with chitin-glucan hyphal walls. Most species produce specialized fruiting bodies called ascocarps whose details of structure help define different species, classes, or orders.

Nonascocarpic representatives such as unicellular yeasts and mildews that reproduce primarily by budding do not form mycelia. Both sexual and asexual reproduction are found within this phylum. This phylum, which also features septate hyphae and chitin-glucan cell walls, is characterized by basidiospores borne upon a club-like structure called a basidium. Approximately 22, species are assigned to three classes: Basidiomycetes, Teliomycetes, and Ustomycetes.

Basidiomycetes include mushrooms, polypores, crusts, corals, clubs, basidiolichens, and jellies, which propel their spores, and "gastromycetes" or "stomach fungi" that passively release their spores puffballs, basidiotruffles ["false truffles"], stinkhorns, and birds' nests. Teliomycetes rusts and Ustomycetes smuts are obligate parasites of insects or plants.

Rusts and smuts have exceedingly complex cycles involving up to five separate spore stages and multiple hosts. This ability to produce spores on different hosts in multiple ways presents a significant economic challenge to agriculture.
