Question

Choose the incorrect statement with respect to basidiomycetes.

• A. They are commonly called as the club fungi
• B. Puccinia and Ustilago belong to this group
• C. The mycelium is branched and septate
  
• D. Basidiospores are produced endogenously on basidia

Answer 1

The correct option is D Basidiospores are produced endogenously on basidia

Basidiomycetes are the most commonly seen fungi. The commonly known forms are mushrooms, puffballs, toadstools, etc. The mycelium in basidiomycetes is well developed, branched and septate.
The reproductive structures called basidia found in the fruiting bodies (basidiocarps) are club-shaped and so they are also called ‘club fungi’. A basidium commonly produces four basidiospores by meiosis. These basidiospores are produced exogenously at the tips of thin outgrowth called sterigmata or directly on the basidium.
Some common members of this group are Agaricus, Ustilago (smut fungi), and Puccinia (rust fungi), etc.
