Species

  1. This group, which contains approximately 15,000 known species, is distinguished by the presence of a club- shaped reproductive organ called the basidium.
  2. Most Agaricomycotina produce four spores on each basidium, but some species produce as few as one or as many as eight spores per basidium. (Web site)

Fungus

  1. Basidiospores: Basidiospores are released from the basidium of a fungus to become spores.

Neoformans

  2. Another distinguishing characteristic is the presence of four basipedal spore chains on the basidium of C. neoformans and C. gattii. (Web site)

Agarics

  1. The agarics always have their basidiospores ejected from the basidium into the area between gill edges.

Diploid Zygote

  1. SYNGAMY & ZYGOT FORMATION Nuclear fusion or syangamy occurs in Basidium, giving rise to diploid zygote, the only diploid cell of the life cycle. (Web site)

Specialized Cells

  1. The spores are borne on specialized cells termed basidia (sing., basidium).

Specialized Cell

  1. Sometimes the basidium (metabasidium) develops from a probasidium, which is a specialized cell which is not elongated like a typical hypha.
  2. Basidiomycetes bear spores on one end of a specialized cell called a basidium.

Nuclei

  1. The paired nuclei fuse to form the diploid basidium, which generates haploid basidiospores.

Dikaryon

  1. The paired dikaryon in the basidium fuse (i.e karyogamy takes place).

Diploid Nucleus

  1. The diploid nucleus is formed in the basidium and immediately undergoes meiosis.

Club

  1. Characterized by perforate septate hyphae and the production of a basidium (club) following sexual reproduction. (Web site)
