A description of the basidiomycetes fungi

Ten Speed Press, Berkeley, California. They form when dikaryotic hyphae divide. Academic Press, New York. The Basidiomycota also includes yeasts single-celled forms; Fell et al.

From McLaughlin, et al. Septate hyphae are divided into compartments separated by cross walls internal cell walls, called septa, that are formed at right angles to the cell wall giving the hypha its shapewith each compartment containing one or more nuclei; coenocytic hyphae are not compartmentalized.

Mating in fungi and Sexual selection in fungi Sexual reproduction with meiosis has been directly observed in all fungal phyla except Glomeromycota [78] genetic analysis suggests meiosis in Glomeromycota as well.

The apex of the backward-growing monokaryotic clamp cell fuses with the subapical cell, reestablishing the dikaryotic condition Fig. It does not continue the infection process, rather it remains dormant for a period and then germinates to form basidia stage "IV"sometimes called a promycelium.

There are no males or females, rather there are compatible thalli with multiple compatibility factors. Almost all fungi covered are microscopic, although a few sheets describe larger species, mostly basidiomycete pathogens.

Three major clades are strongly supported within the Basidiomycota: Basidia are borne on fruiting bodies basidiocarpswhich are large and conspicuous in all but the yeasts, rusts, and smuts. Longmans, Green and Co. This mechanism has been termed a "surface tension catapult" and it results in spores being discharged with a force of about 25, g MoneyPringle et al.

The peridioles carry the spores when they disperse at maturity. Most bastidiospores with friutbodies will not produce these bodies until environmental cues tell them to.

An overview of the higher-level classification of Pucciniomycotina based on combined analyses of nuclear large and small subunit rDNA sequences. This nitrogen promotes the growth of grass behind the advancing margin of the ring, giving it a richer green colour.

Rings of Hygrocybe fruitbodies and zones of lush grass growth caused by this fungus. Neither thallus is male or female. The regular formation of clamp connections must have developed early in basidiomycete evolution, because they are found in all the major clades of Basidiomycota.

One of the unusual types of Basidiomycota are the gasteromycetes.


Other biochemical compounds of Basidiomycota that have practical uses include astaxanthin, a red pigment produced by the basidiomycetous yeast Phaffia used to add color to farmed salmonand certain enzymes from wood-decaying Basidiomycota that have potential applications in paper production and bioremediation decontamination of polluted environments using biological agents.

The following description of the characteristics of Basidiomycota traces the life cycle of a "typical" species, beginning at the site of meiosis.

The basidium is the cell in which karyogamy (nuclear fusion) and meiosis occur, and on which haploid basidiospores are formed (basidia are not produced by asexual Basidiomycota). Description and Significance Basidiomycota is a classification that describes a wide variety of organisms.

It is estimated that there are about 30, species, and more species are being discovered all the time. Members of the Basidiomycota, commonly known as the club fungi or basidiomycetes, produce meiospores called basidiospores on club-like stalks called basidia.


Most common mushrooms belong to this group, as well as rust and smut fungi, which are major pathogens of grains. A fungus (plural: fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms.

These organisms are classified as a kingdom, Fungi, which is separate from the other eukaryotic life kingdoms of plants and animals. Basidiomycota (/ b ə ˌ s ɪ d i oʊ m aɪ ˈ k oʊ t ə /) is one of two large divisions that, together with the Ascomycota, constitute the subkingdom Dikarya (often referred Subkingdom: Dikarya.
