Imperfect Fungi

Structure

Niche

  • Penicillium
  • blue and green molds that grow on decaying fruits, vegetables, jellies,and preserves.

More facts

  • They are called imperfect fungi because there has never been a sexual reproductive stage observed from them.
  • also called "deuteromycetes"
  • The group comprises about 25000 species.
  • Imperfect fungi also include the human-molesting athlete’s foot and yeast infections.
  • Heterotrophic

Life Cycle

Reproduction

  • their sexual form of reproduction has never been observed; hence the name "imperfect fungi." Only their asexual form of reproduction is known, meaning that this group of fungus produces their spores asexually.

  • a special kind of genetic recombination called parasexuality may occur. In parasexuality, genetically distinct nuclei within a common hypha exchange portions of chromosomes.

Features

  • Imperfect fungi give blue, Gorgonzola and Roquefort cheeses their unique flavors, and are used to create penicillin.

  • Some imperfect fungi are parasitic and cause disease in animals and plants.
