Which of the following is not a member of class phycomycetes?

Options

A. Albugo
B. Mucor
C. Rhizopus
D. Neurospora

Answer

To determine which of the following is not a member of the class Phycomycetes, we need to understand the characteristics and examples of this class of fungi.

### Step-by-Step Solution:

1. **Understanding Phycomycetes**:
- Phycomycetes, also known as algal fungi, are considered primitive fungi. They are characterized by having an aseptate mycelium, meaning their mycelium does not have septa (divisions) between cells.

2. **Characteristics of Phycomycetes**:
- The mycelium in Phycomycetes is senocytic, which means it contains multiple nuclei within a single cell due to the absence of septa. This results in a continuous cytoplasm.

3. **Habitat**:
- Phycomycetes are typically found in aquatic environments, which is why they are referred to as algal fungi.

4. **Examples of Phycomycetes**:
- Common examples include **Albugo** (a parasite on mustard plants), **Mucor**, and **Rhizopus** (commonly known as bread mold). These organisms are well-known members of the Phycomycetes class.

5. **Identifying the Odd One Out**:
- The question presents options, one of which is **Neurospora**. It is important to identify whether Neurospora belongs to Phycomycetes or another class.
- Neurospora is actually a member of the class Ascomycetes, not Phycomycetes.

6. **Conclusion**:
- Therefore, the correct answer to the question "Which of the following is not a member of class Phycomycetes?" is **Neurospora**.

### Final Answer:
**Neurospora is not a member of class Phycomycetes.**
