A flask shaped fruiting body of Ascomycetes is called:-

Options

A. Sclerotium
B. Apothecium
C. Cleistothecium
D. Perithecium

Answer

To answer the question "A flask shaped fruiting body of Ascomycetes is called:", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Ascomycetes**: Ascomycetes are a group of fungi characterized by their unique reproductive structures. They produce spores in a sac-like structure called an ascus.

2. **Identify the Types of Fruiting Bodies**: The question provides four options: Sclerotium, Apothecium, Clistothecium, and Perithecium. We need to analyze each option to determine which one is flask-shaped.

3. **Examine Sclerotium**:
- Sclerotium is a compact mass of fungal mycelium that is hardened.
- It serves as a food reserve but does not have a flask shape.

4. **Examine Apothecium**:
- Apothecium is a fruiting body that is typically disc-shaped or cup-shaped.
- It is not flask-shaped, so this option can be eliminated.

5. **Examine Clistothecium**:
- Clistothecium is a closed, spherical fruiting body that does not have a flask shape.
- This option can also be eliminated.

6. **Examine Perithecium**:
- Perithecium is described as a flask-shaped fruiting body.
- It has an opening (ostiole) through which spores are released, confirming its flask-like structure.

7. **Conclusion**: After analyzing all the options, we find that the correct answer is **Perithecium**, as it is the only one that is flask-shaped.

### Final Answer:
A flask shaped fruiting body of Ascomycetes is called **Perithecium**.
