D. Albugo

Answer

To solve the question "All the following belong to phycomycetes except-", we will analyze each of the given options to determine which one does not belong to the group of phycomycetes.

### Step-by-Step Solution:

1. **Understanding Phycomycetes**:
- Phycomycetes, also known as the "lower fungi," are a group of fungi that are primarily saprophytic and can be found in various environments such as soil, air, and decaying organic matter. They are characterized by their filamentous structure and are often associated with algae.

2. **Analyzing the Options**:
- **Option A: Penicillium**:
- Penicillium is a genus of fungi that is not classified under phycomycetes. It belongs to the group called Ascomycetes (sac fungi), which are distinct from phycomycetes.
- **Option B: Rhizopus**:
- Rhizopus is commonly known as bread mold and is indeed a member of the phycomycetes group.
- **Option C: Mucor**:
- Mucor is another genus of fungi that falls under phycomycetes, known for its role in decomposition.
- **Option D: Albugo**:
- Albugo is also a member of phycomycetes, specifically known for being a plant pathogen.

3. **Identifying the Odd One Out**:
- After analyzing all the options, it is clear that Penicillium is the only organism that does not belong to phycomycetes. Instead, it is classified under Ascomycetes.

4. **Conclusion**:
- Therefore, the correct answer to the question is **Penicillium**.

### Final Answer:
Penicillium does not belong to phycomycetes.
