A group of fungi with septate mycelium and sexual reproduction either absent or not known is

Options

A. Phycomycetes (algal fungi )
B. Basidiomycetes (club fungi )
C. Deuteromycetes (imperfect fungi )
D. Ascomycetes (sea fungi )

Answer

To solve the question "A group of fungi with septate mycelium and sexual reproduction either absent or not known is", we can follow these steps:

### Step 1: Understand the Characteristics of Fungi
We need to identify the characteristics mentioned in the question:
1. Septate mycelium
2. Sexual reproduction either absent or not known

### Step 2: Analyze the Options
We have four options to consider:
1. **Phycomycetes**: These fungi have non-septate mycelium, so this option is incorrect.
2. **Basidiomycetes**: Known as club fungi, they do have sexual reproduction, so this option is also incorrect.
3. **Deuteromycetes**: Also known as imperfect fungi, they have septate mycelium and sexual reproduction is either absent or not well understood.
4. **Ascomycetes**: Known as sac fungi, they perform asexual reproduction and sexual reproduction is also present, so this option is incorrect.

### Step 3: Identify the Correct Answer
From the analysis, the only group that fits the criteria of having septate mycelium and sexual reproduction that is either absent or not known is **Deuteromycetes**.

### Conclusion
The correct answer is **Deuteromycetes**.
