For example, the chanterelle genus Craterellus often has six-spored basidia, while some corticioid Sistotrema species can have two-, four-, six-, or eight-spored basidia, and the cultivated button mushroom, Agaricus bisporus. can have one-, two-, three- or four-spored basidia under some circumstances. Occasionally, monokaryons of some taxa can ...
This is a list of families in the phylum Basidiomycota of kingdom Fungi.The Basidiomycota are the second largest phyla of the fungi, containing 31515 species. [1] The phylum is divided into three subphyla, the Pucciniomycotina (rust fungi), the Ustilaginomycotina (smut fungi), the Agaricomycotina, and two classes of uncertain taxonomic status (incertae sedis), the Wallemiomycetes and the ...
Most basidiospores are forcibly discharged, and are thus considered ballistospores. [3] These spores serve as the main air dispersal units for the fungi. The spores are released during periods of high humidity and generally have a night-time or pre-dawn peak concentration in the atmosphere.
A basidium-producing organ; the fruiting body of Basidiomycota. [44] Basidiomycota A Lactarius indigo, a milk-cap mushroom and basidiomycete. Basidiomycetes. A phylum of fungi. Generally defined by sexual reproduction via basidiospores formed from a basidium, although a few purely anamorphic basidiomycetes exist.
The phylum Basidiomycota are commonly known as "superior fungi" due to their production of well-developed septate hyphae and fruiting bodies. Some basidiomycetes commonly produce visible structures such as mushrooms and puffballs. They are characterized by the asexual production of Basidiospores. [13]
Agaricomycotina is one of three subdivisions of the Basidiomycota (fungi bearing spores on basidia), and represents all of the fungi which form macroscopic fruiting bodies.. Agaricomycotina contains over 30,000 species, [1] divided into three classes: Tremellomycetes, Dacrymycetes, and Agaricomycetes.
The phylum Basidiomycota can be divided into three major lineages: mushrooms, rusts and smuts. Fusion of haploid nuclei ( karyogamy ) occurs in the basidia, club-shaped end cells. Shortly after formation of the diploid cell, meiosis occurs and the resulting four haploid nuclei migrate into four, usually external cells called basidiospores .
In addition to having septate basidia, heterobasidiomycetes also frequently possess large irregularly shaped sterigmata and spores that are capable of self-replication – a process where a spore, instead of germinating into a vegetative hypha, gives rise to a sterigma and a new spore, which is then discharged as if from a normal basidium.
