Several other species are important for the making of cheeses, such as blue cheese, Roquefort, and Camembert. Basidiomycota are typically filamentous fungi composed of hyphae. Most Deuteromycota have only asexual reproduction as the sexual stage of the life cycle has been lost or has yet to be discovered. Deuteromycetes is a class of fungi that shows only asexual reproduction in their life cycle. Deuteromycetes are an artificial group of fungi, of which there exist approximately fifteen thousand species, often referred to as “fungi imperfecti” because their only known reproductive mechanism is asexual. This article was most recently revised and updated by, https://www.britannica.com/science/deuteromycetes. Most of them are parasitic and cause various diseases.

A lot of fungi had no known sexual stage in their life cycle, and they were classified under Deuteromycetes. Hence they are grouped under an artificial group called fungi imperfecti. You're likely to see examples of zygomycetes everywhere you look. Only their asexual form of reproduction is known, meaning that these fungi produce their spores asexually, in the process called sporogenesis. (ii) Acervulus and Sporodochium Producing Forms: These Deuteromycetes produce small or large cushion-like masses of hyphae with a bed of short conidiophores from which conidia are produced. The deuteromycetes, commonly called molds, are “second-class” fungi that have no known sexual state in their life cycle, and thus reproduce only by producing spores via mitosis.About 90% of these have affinities to the Ascomycota. …the sac fungi, and the Deuteromycetes, or the imperfect fungi (i.e., fungi in which no sexual reproductive stages are known). The … Since most of the conidia structures look like ascomycetes type, they are believed to be derived from ascos who lost the ability to reproduce sexually. & P. They do not reproduce sexually. For example, members of the Deuteromycetes such as Aspergillus, Penicillium and Trichoderma species are known to produce numerous extracellular enzymes, which are put to good use in biotechnology (Elander, 1989; Wainwright, 1992; Smith, 1996). 1.
