  2. Basidium - Wikipedia

    en.wikipedia.org/wiki/Basidium

    A basidium usually bears four sexual spores called basidiospores. Occasionally the number may be two or even eight. Each reproductive spore is produced at the tip of a narrow prong or horn called a sterigma (pl. sterigmata), and is forcefully expelled at full growth. The word basidium literally means "little pedestal". This is the way the ...

  3. Basidiospore - Wikipedia

    en.wikipedia.org/wiki/Basidiospore

    Typically, four basidiospores develop on appendages from each basidium, of which two are of one strain and the other two of its opposite strain. In gills under a cap of one common species, there exist millions of basidia. Some gilled mushrooms in the order Agaricales have the ability to release billions of spores. [1]

  4. Basidiomycota - Wikipedia

    en.wikipedia.org/wiki/Basidiomycota

    Often such species form only two spores per basidium, but that too varies. Following meiosis, mitotic divisions can occur in the basidium. Multiple numbers of basidiospores can result, including odd numbers via degeneration of nuclei, or pairing up of nuclei, or lack of migration of nuclei.

  5. Sporocarp (fungus) - Wikipedia

    en.wikipedia.org/wiki/Sporocarp_(fungus)

    The sporocarp (also known as fruiting body, fruit body or fruitbody) of fungi is a multicellular structure on which spore-producing structures, such as basidia or asci, are borne. The fruitbody is part of the sexual phase of a fungal life cycle, [1] while the rest of the life cycle is characterized by vegetative mycelial growth and asexual ...

    A propagative sexual spore produced on a basidium, typically following karyogamy and meiosis, typically containing one or two haploid nuclei. [46] basidium. pl. basidia. A cell or organ where basidiospores are produced, generally four. Basidia are characteristic of basidiomycetes. From Greek basis, base. [47] basipetal

  7. Basidiocarp - Wikipedia

    en.wikipedia.org/wiki/Basidiocarp

    All basidiocarps serve as the structure on which the hymenium is produced. Basidia are found on the surface of the hymenium, and the basidia ultimately produce spores. In its simplest form, a basidiocarp consists of an undifferentiated fruiting structure with a hymenium on the surface; such a structure is characteristic of many simple jelly and club fungi.

  8. Heterobasidiomycetes - Wikipedia

    en.wikipedia.org/wiki/Heterobasidiomycetes

    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.

  9. Ceratobasidium - Wikipedia

    en.wikipedia.org/wiki/Ceratobasidium

    These affinities were the possession of large sterigmata ("cerato basidium" means "horned basidium") and the production of basidiospores that produce secondary spores. [2] Four species were originally placed in the genus, with subsequent authors adding a further 35 species. [3]
