Which of the following does not apply to ascomycetes

Options

A. Mycelium is coenocytic and aseptate
B. Commonly known sac fungi and
spore produced exogenously
C. Asexual sproes called conidia are produced exogenously
D. Sexual spores called ascospores are produced endogenously

Answer

To solve the question "Which of the following does not apply to ascomycetes?", we need to analyze the characteristics of ascomycetes and compare them with the options provided.

### Step-by-Step Solution:

1. **Understanding Ascomycetes**:
- Ascomycetes, also known as sac fungi, are a group of fungi characterized by their unique reproductive structures. They are one of the four major groups of fungi.

2. **Mycelium Structure**:
- Ascomycetes have a mycelium that is **septate** (divided by septa) and **branched**. This is a key characteristic that differentiates them from other fungal groups, such as phycomycetes, which have a coenocytic (aseptate) mycelium.

3. **Identifying the Options**:
- We need to evaluate the options given in the question to find out which one does not apply to ascomycetes.

4. **Evaluating Option A**:
- If option A states that "mycelium is synocytic and aseptic", this is incorrect for ascomycetes as their mycelium is septate and branched.

5. **Evaluating Other Options**:
- Option B: If it states that ascomycetes are commonly known as sac fungi and produce spores exogenously, this is correct.
- Option C: If it mentions that asexual spores are known as conidia and are produced exogenously, this is also correct.
- Option D: If it states that sexual spores are called ascospores and are produced endogenously in a sac-like structure, this is also correct.

6. **Conclusion**:
- Since option A is the only statement that does not apply to ascomycetes, it is the correct answer to the question.

### Final Answer:
**Option A does not apply to ascomycetes.**
