Coenocytic mycelium is found in

Options

A. Deuteromycetes
B. Phycomycetes
C. Ascomycetes
D. All of these

Answer

To answer the question "Coenocytic mycelium is found in," we will analyze the characteristics of the different groups of fungi mentioned in the options: Deuteromycetes, Phycomycetes, and Ascomycetes.

### Step-by-Step Solution:

1. **Understanding Mycelium and Hyphae**:
- Fungi are made up of structures called hyphae. These hyphae can be classified into two types: septate (with compartments) and aseptate (without compartments).

2. **Defining Coenocytic Mycelium**:
- Coenocytic mycelium refers to a type of mycelium that is aseptate, meaning it does not have compartments. Instead, it is a continuous mass of cytoplasm that contains multiple nuclei.

3. **Analyzing the Options**:
- **Deuteromycetes**: This group is known as "imperfect fungi" and typically does not have coenocytic mycelium. They usually have septate hyphae.
- **Phycomycetes**: This group includes fungi that have coenocytic mycelium. They are characterized by aseptate hyphae, which means they are multi-nucleated and lack compartments.
- **Ascomycetes**: Also known as sac fungi, they generally have septate hyphae and do not exhibit coenocytic mycelium.

4. **Conclusion**:
- Based on the characteristics of the groups, coenocytic mycelium is found in **Phycomycetes**.

### Final Answer:
Coenocytic mycelium is found in **Phycomycetes**.
