Text Box: 2. Within each basidium, two haploid nuclei fuse to form diploid nuclei.

 

Text Box: fused hypha

 

Text Box: + Mating type
Text Box: - Mating type
Text Box: 4. Hyphae from different
    mating types fuse.The
    fused hyphae grow and
    form a fruiting body
Text Box: 3. Meiosis produces four haploid spores.  A spore can germinate into a haploid hypha.
Text Box: basidia

Text Box: basidium
Text Box: Diploid nuclei (2n)
Text Box: spore (n)
Text Box: Gills lined with basidia
Text Box: 1. Spores are produced in club-shaped structures called basidia, which line the gills.
