A group of fungi with septate mycelium in which sexual reproduction is either unknown or lacking are classified under

Options

A. Phycomycetes
B. Deuleromycetes
C. Basidiomycetes
D. Ascomycetes.

Answer

To solve the question, we need to identify the classification of a group of fungi that has septate mycelium and lacks sexual reproduction. Here’s the step-by-step solution:

### Step 1: Understand the Characteristics of Fungi
- Fungi can be classified based on their mycelium structure and reproductive methods.
- Mycelium can be septate (divided into compartments) or aseptate (not divided).

### Step 2: Analyze the Options
1. **Phycomyces**:
- This group has aseptate mycelium, so it does not fit the description of having septate mycelium.
- **Conclusion**: Incorrect option.

2. **Deuteromyces**:
- This group is characterized by having septate mycelium.
- Sexual reproduction is either unknown or lacking in this group.
- **Conclusion**: This fits the description perfectly.

3. **Basidiomycetes**:
- This group has septate mycelium, but sexual reproduction is present.
- **Conclusion**: Incorrect option.

4. **Ascomycetes**:
- This group also has septate mycelium and includes fungi that reproduce sexually.
- **Conclusion**: Incorrect option.

### Step 3: Final Conclusion
- Based on the analysis, the correct classification for the group of fungi with septate mycelium in which sexual reproduction is either unknown or lacking is **Deuteromyces**.

### Answer:
The group of fungi with septate mycelium in which sexual reproduction is either unknown or lacking are classified under **Deuteromyces**.
