Question:
Which of the following does not belong to the class basidiomycetes?
Options:
  • 1. Agaricus
  • 2. Ustilago
  • 3. Alternaria
  • 4. Puccinia
Solution:
Page 24, XI NCERT. The fungus that does not belong to the class Basidiomycetes is Alternaria. Alternaria belongs to the class Dothideomycetes, which is a class of ascomycete fungi. Agaricus, Ustilago, and Puccinia all belong to the class Basidiomycetes. Agaricus is a genus of edible mushrooms, Ustilago is a genus of plant pathogenic fungi that causes smut disease, and Puccinia is a genus of plant pathogenic fungi that causes rust disease.
