A basidium (pl.: basidia) is a microscopic spore-producing structure found on the hymenophore of reproductive bodies of basidiomycete fungi. The presence of basidia is one of the main characteristic features of the group.

basidium, in fungi (kingdom Fungi), the organ in the members of the phylum Basidiomycota (q.v.) that bears sexually reproduced bodies called basidiospores. The basidium serves as the site of karyogamy and meiosis, functions by which sex cells fuse, exchange nuclear material, and divide to reproduce basidiospores.

The basidium (pl. basidia) is a cell on which the sexual spores (basidiospores) of basidiomycetes are produced. Usually it is club-shaped… Usually it is club-shaped, there are four basidiospores on pegs called sterigmata (sing.

What is Basidium? Basidium Definition Biology: Upon being asked the basidium definition biology, we can say that A basidium is a small sporangium found on the hymenophore of basidiomycete fungi's fruiting bodies, sometimes known as tertiary mycelium since it develops from secondary mycelium. Tertiary mycelium is a dikaryon of heavily coiled ...

Dec 15, 2021 · The fungi in the Phylum Basidiomycota are easily recognizable under a light microscope by their club-shaped fruiting bodies called basidia (singular, basidium), which are the swollen terminal cell of a hypha.

Feb 28, 2021 · A basidium is the fruiting body of a mushroom-producing fungus, and it forms four basidiocarps. The result of the plasmogamy step is four basidiospores. Karyogamy results directly in the formation of mycelia.

Jan 16, 2025 · Explore the intricate structures of basidia and the processes behind spore formation in fungi, highlighting their diversity and biological significance. Basidia play a key role in the reproductive cycle of fungi, particularly within the Basidiomycota phylum.

A basidium (plural basidia) is a microscopic type of spore-producing cell found on certain fungi. Most often the basidia are elongated and club shaped. But there is variation in the shape. [1] A basidium usually bears four sexual spores called basidiospores. [2]

Feb 21, 2023 · The main difference between paraphyses and basidium is that paraphyses is a tiny joined filaments growing among archegonia and antheridia of mosses, whereas basidium is a small club-shaped structure bearing spores that occur in Basidiomycota, a division of fungi.

Basidium. The basidium is a clublike structure with 2–4 apical sterigmata that bear basidiospores. It is usually entire but is divided longitudinally in Auriculariales and Platygloeales.
