Dust-bin group of fungi is :

Options

A. Ascomycetes
B. Deuteromycetes
C. Zygomycetes
D. Basidiomycetes

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks about the "dust-bin group of fungi." This term refers to a specific classification of fungi that do not fit neatly into the established categories.

2. **Identifying the Options**: The options provided are Ascomycetes, Deuteromycetes, Zygomycetes, and Basidiomycetes. We need to determine which of these is referred to as the dust-bin group.

3. **Defining Deuteromycetes**: Deuteromycetes, also known as "imperfect fungi," are fungi for which the sexual reproductive stage has not been observed. This lack of sexual reproduction is a key characteristic that leads to their classification as a dust-bin group.

4. **Characteristics of Deuteromycetes**: These fungi reproduce asexually, primarily through structures called conidia. The term "conidia" comes from the Greek word "koinis," meaning dust, which is why they are associated with the dust-bin group.

5. **Conclusion**: Based on the characteristics and definitions, the correct answer to the question is Deuteromycetes (option B), as they are classified as the dust-bin group of fungi due to their imperfect nature and asexual reproduction.

**Final Answer**: The dust-bin group of fungi is Deuteromycetes.
