Coenocytic, multinucleate and branched mycellal habit is found in-

Options

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

Answer

To solve the question regarding which group exhibits coenocytic, multinucleate, and branched mycelial habits, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Coenocytic**: This refers to a type of fungal structure where there are no septa (cross-walls) dividing the hyphae, resulting in a continuous cytoplasmic mass containing multiple nuclei.
- **Multinucleate**: This indicates that there are multiple nuclei present within a single cell or structure.
- **Branched Mycelium**: This refers to the branching structure of the mycelium, which is the vegetative part of a fungus.

2. **Identify the Options**:
- The options provided are:
- A) Basidiomycetes
- B) Hyphomycetes
- C) Ascomycetes
- D) Deuteromycetes
- E) Phycomycetes

3. **Analyze Each Group**:
- **Basidiomycetes**: Typically have septate hyphae and do not exhibit coenocytic conditions.
- **Hyphomycetes**: Generally have septate hyphae, so they do not fit the coenocytic description.
- **Ascomycetes**: Also possess septate hyphae, which means they do not exhibit the coenocytic condition.
- **Deuteromycetes**: While they can have some forms of mycelium, they usually have septate structures.
- **Phycomycetes**: This group is characterized by coenocytic hyphae, meaning they lack septa, and they can have multiple nuclei within a single cell. They also exhibit branched mycelium.

4. **Conclusion**:
- Based on the analysis, the group that exhibits coenocytic, multinucleate, and branched mycelial habit is **Phycomycetes**.

### Final Answer:
**Phycomycetes** (Option E)
