Which statement is not correct ?

Options

A. Phycomycetes are also called algal fungi
B. Septate mycelium is present in phycomycetes
C. Some ascomycetes like morels, truffles are edible
D. Deuteromycetes is also known as false class

Answer

To determine which statement is not correct regarding the classifications of fungi, we will analyze each statement provided in the question step by step.

### Step 1: Analyze the first statement
- **Statement**: Phycomycetes are also called algal fungi.
- **Evaluation**: This statement is correct. Phycomycetes, which include organisms like Chytridiomycetes and Zygomycetes, are indeed referred to as algal fungi due to their similarities with algae.

**Hint**: Remember that phycomycetes are linked to aquatic environments and have characteristics similar to algae.

### Step 2: Analyze the second statement
- **Statement**: Septate mycelium is present in phycomycetes.
- **Evaluation**: This statement is incorrect. Phycomycetes typically have a coenocytic (aseptate) mycelium, which means their hyphae do not have septa (cross walls) separating the cells. Instead, they have multiple nuclei within a single cell-like structure.

**Hint**: Focus on the structure of mycelium in different fungal groups; phycomycetes lack septa.

### Step 3: Analyze the third statement
- **Statement**: Some ascomycetes like morrels, truffles are edible.
- **Evaluation**: This statement is correct. Many ascomycetes, such as morels and truffles, are known for being edible and are considered delicacies.

**Hint**: Recall examples of edible fungi and their classifications; ascomycetes include many culinary favorites.

### Step 4: Analyze the fourth statement
- **Statement**: Deuteromycetes are also known as false fungi.
- **Evaluation**: This statement is correct. Deuteromycetes, also known as fungi imperfecti, are termed "false fungi" because they do not have a known sexual reproduction stage.

**Hint**: Think about the reproductive methods of fungi and how deuteromycetes differ from other groups.

### Conclusion
After evaluating all statements, the incorrect statement is the second one: "Septate mycelium is present in phycomycetes."

**Final Answer**: The statement that is not correct is: "Septate mycelium is present in phycomycetes."
