- The club-shaped, spore -bearing organ (basidium) is borne on a usually large and conspicuous fruiting body.
- At a late stage of development, some of these hyphae produce special cells termed basidia (singular, basidium).
- After cell fusion a dikaryotic filament develops, at the tip of which a basidium gives rise to four chains of basidiospores.
- Meiosis occurs within the basidium, and the four products are extruded from the tip of the basidium on sterigma (below).

- This group, which contains approximately 15,000 known species, is distinguished by the presence of a club- shaped reproductive organ called the basidium.
- Most Agaricomycotina produce four spores on each basidium, but some species produce as few as one or as many as eight spores per basidium.
- Basidiospores: Basidiospores are released from the basidium of a fungus to become spores.
- Four chains of basidiospores, the sexual spores of C. neoformans, are then produced from each basidium.
- Another distinguishing characteristic is the presence of four basipedal spore chains on the basidium of C. neoformans and C. gattii.
- The agarics always have their basidiospores ejected from the basidium into the area between gill edges.
- SYNGAMY & ZYGOT FORMATION Nuclear fusion or syangamy occurs in Basidium, giving rise to diploid zygote, the only diploid cell of the life cycle.
- The spores are borne on specialized cells termed basidia (sing., basidium).
- Sometimes the basidium (metabasidium) develops from a probasidium, which is a specialized cell which is not elongated like a typical hypha.
- Basidiomycetes bear spores on one end of a specialized cell called a basidium.
- The paired nuclei fuse to form the diploid basidium, which generates haploid basidiospores.
- The paired dikaryon in the basidium fuse (i.e karyogamy takes place).
- The diploid nucleus is formed in the basidium and immediately undergoes meiosis.
- Characterized by perforate septate hyphae and the production of a basidium (club) following sexual reproduction.
- Basidiomycota commonly are known as club fungi, given the club-shaped basidium.
- The spores are usually attached to the basidium by short spikes called sterigmata (singular: sterigma).
- Note that each basidium produces four stalks (sterigmata) and the basidiospores develop on the ends of these stalks.
- This results in the formation of four basidiospores, which are attached to the basidium by means of sterigmata (short stalks).
- Sexual reproduction of the club fungi begins upon fusion of two primary hyphae to form a club-shaped structure, known as a basidium.
- Second, the two haploid nuclei inside the basidium fuse together to form a diploid zygote.
- Each cell swells to form a diploid basidium, which rapidly undergoes meiosis and yields four haploid nuclei.
- At the pointed tip of the spore (the hilum) closest to the supporting basidium, Buller's drop accumulates as a large, almost spherical water droplet.
- Basidiospores (bah-sid-ee-oh-spores) - A spore formed on a structure known as a basidium.
- The mycelium within this structure remains as a dikaryon, diploid formation only occurring within the modified hyphal tip called the basidium.
- The spores are released from the basidium when they mature and are spread by the wind.
- When a spore is mature it is forcibly shot from the basidium, into the air space between the gills.
- They reproduce by sexually produced spores on a club shaped structure called a basidium.
- Basidiospores are sexually produced fungal spore that is born on basidium.
- AHCC is a compound made from several subspecies of mushroom from the phylum Basidiomycota, which produce spores outside of the pedestal like basidium.
- The phylum Basidiomycota, or club fungi, gets its name from the basidium, a specialized reproductive structure that resembles a club.
- Species in this phylum produce spores on a club-like structure called the basidium.
- The name of the phylum is derived from the basidium, a transient diploid stage.
- Fusion of cells on tips of hyphae result in basidiospores on a basidium during the sexual part of the life cycle.
- The cells of the teliospore germinates to produce a short germ tube that will develop into a basidium that is essentially transversely septate.
- A structure in the hymenium of a member of the Basidiomycotina that is morphologically similar to a basidium without sterigmata.
- The basidium may grow free or be attached to a surface called the hymenium.
- It may be an immature basidium or a permanently sterile structure in the hymenium.
- T Teliospore - Thick-walled resting spore produced by some fungi, notably rusts and smuts, that germinates to form a basidium.
- Teliospore (sometimes called teleutospore) is the thick-walled resting spore of some fungi (rusts and smuts), from which the basidium arises.
- At the end of the hypha a structure called the basidium, a spore-producing, club-shaped structure.
- Terminal cells in the hypha of the fruiting body undergo karyogamy producing a diploid basidium.
- The spore s of puffballs are statismospores rather than ballistospores, meaning they are not actively shot off the basidium.
- Basidiomycota - Sexual reproduction in a sack called a basidium with the production of basidiospores (figure 2).
