A dolipore septum is a characteristic feature of

Options

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

Answer

To answer the question regarding the characteristic feature of a dolipore septum, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Dolipore Septum**:
- A dolipore septum is a specialized type of septum (a dividing wall) found in certain fungi. It is characterized by a barrel-shaped swelling around a central pore.

2. **Identifying the Fungal Groups**:
- The question lists four groups of fungi: phycomycetes, ascomycetes, basidiomycetes, and zygomycetes. We need to determine which of these groups is associated with dolipore septa.

3. **Researching Fungal Characteristics**:
- Dolipore septa are specifically found in the phylum Basidiomycota (basidiomycetes). This group includes mushrooms, puffballs, and shelf fungi, which have distinct structural features.

4. **Comparing with Other Groups**:
- Phycomycetes (now often referred to as Zygomycetes) and Ascomycetes do not possess dolipore septa. Zygomycetes have simple septa, while Ascomycetes have different types of septal structures.

5. **Conclusion**:
- Therefore, the dolipore septum is a characteristic feature of Basidiomycetes.

### Final Answer:
A dolipore septum is a characteristic feature of **Basidiomycetes**.
