Answer

To determine how many of the listed organisms belong to the Ascomycota (sac fungi), we will analyze each organism one by one based on their classification.

1. **Aspergillus**: This is a genus of fungi that is classified under Ascomycota.
- **Hint**: Remember that Aspergillus is commonly known for its role in fermentation and as a model organism in research.

2. **Rhizopus**: This genus is not part of Ascomycota; it belongs to the Zygomycota group.
- **Hint**: Rhizopus is often associated with bread mold.

3. **Agaricus**: This is a genus that includes mushrooms, specifically the common edible mushroom, and it belongs to Basidiomycota.
- **Hint**: Agaricus is well-known for its culinary uses.

4. **Claviceps**: This genus is part of Ascomycota and is known for producing ergot, a substance that can affect rye and other grains.
- **Hint**: Claviceps is often studied for its historical significance in medicine and agriculture.

5. **Neurospora**: This is also a genus of fungi that belongs to Ascomycota and is often used in genetic studies.
- **Hint**: Neurospora is frequently used in laboratory experiments due to its rapid growth.

6. **Albugo**: This genus is not classified under Ascomycota; it belongs to Oomycetes.
- **Hint**: Albugo is known for causing white rust disease in plants.

7. **Erysiphe**: This genus is part of Ascomycota and is known for causing powdery mildew on plants.
- **Hint**: Erysiphe is significant in agriculture due to its impact on crops.

8. **Alternaria**: This genus is not classified under Ascomycota; it belongs to Deuteromycetes (Fungi Imperfecti).
- **Hint**: Alternaria is often associated with plant diseases.

9. **Penicillium**: This genus is classified under Ascomycota and is famous for its role in antibiotic production (penicillin).
- **Hint**: Penicillium is crucial in both medicine and food production.

Now, let's summarize the findings:
- Ascomycota: Aspergillus, Claviceps, Neurospora, Erysiphe, Penicillium
- Not Ascomycota: Rhizopus, Agaricus, Albugo, Alternaria

Counting the Ascomycota organisms, we find a total of **5** organisms belong to Ascomycota.

**Final Answer**: 5
