Select the mismatched pair.

Options

A. Apothecium - Peziza
B. Ascostroma - Pleospora
C. Perithecium - Claviceps
D. Cleistothecium - Neurospora

Answer

To solve the question of selecting the mismatched pair, we need to analyze each option provided in relation to the types of ascocarps and their corresponding examples.

### Step-by-Step Solution:

1. **Understand the Types of Ascocarps:**
- Ascocarps are reproductive structures in certain fungi, particularly in the Ascomycetes group. They come in various shapes and forms.

2. **Analyze the Options:**
- **Option 1:** Apothecium - This is a cup-like structure. Example: *Peziza*.
- **Match:** Correctly matched.

- **Option 2:** Perithecium - This is a flask-shaped structure. Example: *Claviceps*.
- **Match:** Correctly matched.

- **Option 3:** Cleistothecium - This is a closed ascocarp. Example: *Penicillium*.
- **Match:** Correctly matched.

- **Option 4:** Ascostroma - This is a cushion-like, chambered structure. Example: *Pleospora*.
- **Match:** Correctly matched.

- **Option 5:** Identify if there is another option or if the question is only about the four given options.

3. **Identify the Mismatched Pair:**
- After analyzing all the options, it appears that all the pairs are correctly matched. However, if we consider the context of the question, we need to ensure that we are looking for any discrepancies in the descriptions or examples provided.

4. **Conclusion:**
- Based on the analysis, the mismatched pair is **Option 4** (Cleistothecium with *Penicillium*), as it is not a typical example of a Cleistothecium structure.

### Final Answer:
The mismatched pair is **Option 4**.
