Mark the correct statement.
(a) Phycomycetes include mushrooms, bracket fungi or puff balls
(b) The mycelium of basidiomycetes is branched and septate
(c) Neurospora is used extensively in biochemical and genetic work, it belong to group basidiomycetes
(d) Morels and truffles are non-edible

Options

A. Phycomycetes include mushrooms, bracket fungi or puff balls
B. The mycelium of basidiomycetes is branched and septate
C. Neurospora is used extensively in biochemical and genetic work, it belong to group basidiomycetes
D. Morels and truffles are non-edible

Answer

To determine the correct statement from the options given, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze Statement (a)**: "Phycomycetes include mushrooms, bracket fungi or puff balls."
- **Explanation**: Phycomycetes is a group of fungi that primarily includes algae-like fungi such as molds and is not known for including mushrooms, bracket fungi, or puffballs. These types of fungi are actually classified under Basidiomycetes.
- **Conclusion**: This statement is **incorrect**.

2. **Analyze Statement (b)**: "The mycelium of basidiomycetes is branched and septate."
- **Explanation**: Basidiomycetes are known for having a complex structure. Their mycelium is indeed branched and contains septa (cross-walls), which is a characteristic feature of this group of fungi.
- **Conclusion**: This statement is **correct**.

3. **Analyze Statement (c)**: "Neurospora is used extensively in biochemical and genetic work; it belongs to group basidiomycetes."
- **Explanation**: Neurospora is a genus of fungi that is widely used in genetic research, but it actually belongs to the group Ascomycetes, not Basidiomycetes. This is a common misconception.
- **Conclusion**: This statement is **incorrect**.

4. **Analyze Statement (d)**: "Morels and truffles are non-edible."
- **Explanation**: Morels and truffles are highly regarded as edible fungi and are considered delicacies in many cuisines. Therefore, stating that they are non-edible is false.
- **Conclusion**: This statement is **incorrect**.

### Final Conclusion:
The only correct statement among the options is **(b)**: "The mycelium of basidiomycetes is branched and septate."
