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.

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 ...

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.

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. Phragmobasidium. A phragmobasidium is a basidium divided into separate cells following meiosis, as in Auriculariales and Platygloeales. In cross-section the ...

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 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.

Jan 9, 2025 · Basidia are specialized structures found predominantly in the Basidiomycota, a major division of fungi. Typically club-shaped, they serve as the site for spore production. The morphology of basidia can vary, but they generally consist of a swollen terminal cell that supports spore development.

Basidium is a specialized cell that produces sexual spores called basidiospores, while paraphysis is a sterile cell that helps support the basidia and aid in the dispersal of spores. Basidia are typically club-shaped and found on the surface of the basidiocarp, while paraphyses are thread-like structures interspersed among the basidia.
