General Overview:

• Sexual reproduction invoves formation of basidia and basidiospores
• Members have complex septate hyphae
• Members of the Basidiomycetes class are dikaryotic - multiple nuclei per cell without fusing still (N) haploid

See Pictures below

Classification of Basidiomycota:

Domain: Eukarya

Kingdom: Fungi

Phylum (division): Basidiomycota

Major Classes:

Teliomycetes (Rusts) | Ustomycetes (smuts) | Basidiomycetes

Class: Teliomycetes (Rusts)

• Serious parasites of plants
• Does not produce basidiocarps
• Basidia often septate or forked

Puccinia graminis (wheat rust)

• Life cycle includes, aecia, spermagonia stages on a barberry plant
• uredinia and telia stages on the wheat plant
• See: wheat rust life cycle

Gymnosporangium (ceadar apple rust)

• Another rust that infects apple trees
• Can be devistating to apple orchards

Class: Ustomycetes (Smuts)

• Parcites similar to Teliomycetes with septate basidia but usually with only one host

Ustilago maydis (corn smut)

• A smut that infects corn

Class: Basidiomycetes

Orders (series):

• Hymenomycetes - mushrooms, bracket fungi, coral fungi

  • Basidia are produced on the basidiocarp.
  • Basidia are non-septate, swollen, and club-shaped produced on a fertile layer called hymenium
  • Most are saprophytes

• Gasteromycetes - puffballs, stinkhorns, bird's nest fungi

• Basidia are produced in the basidiocarp
• Examples:
  • Stinkhorns, bird's nest fungi, and puffballs
