Question

Which fungi do not have a perfect stage in their life?

Answer 1

Deuteromycetes:

1. Fungi classified as Deuteromycetes, or "imperfect fungus," have no known sexual stage during their life cycle. Alternaria, Colletotrichum, and Trichoderma are examples of this.
2. Deuteromycetes are saprophytes that live on a variety of substrates, but they may also live as parasites.
3. Their cell wall is mostly made up of chitin-glucan.
4. For asexual reproduction, hyphal fragments, budding, and most frequently conidia or conidiospores are employed.
5. Conidiophores can be free or aggregated to produce specialized structures like synnemata and sporodochia.
6. Deuteromycetes are prevalent in soil, where they play an important role in the breakdown of organic materials and, as a result, in the natural recycling of nutrients.
7. Deuteromycetous fungi are so crucial in fermentation that there would be no fermentation if they weren't used.
