Fungi are classfied on the basis of-

Options

A. Morphology of mycellum
B. Mode of spore formation
C. Development of fruiting bodies
D. All

Answer

### Step-by-Step Solution:

1. **Understanding Fungi Classification**: Fungi are classified into different groups based on specific characteristics. The primary criteria for classification include the structure and formation processes within the fungi.

2. **Morphology of Mycelium**: The first criterion for classification is the morphology of mycelium. Mycelium is the vegetative part of fungi, consisting of a network of fine white filaments (hyphae). The structure, arrangement, and type of mycelium can vary among different fungi, which helps in their classification.

3. **Mode of Spore Formation**: The second criterion is the mode of spore formation. Fungi reproduce by forming spores, and the method of spore production can differ significantly. Some fungi produce spores sexually, while others do so asexually. This difference is crucial for classification.

4. **Development of Fruiting Bodies**: The third criterion is the development of fruiting bodies. Fruiting bodies are the reproductive structures that produce and release spores. The presence, type, and complexity of these structures can vary widely among fungi, aiding in their classification.

5. **Conclusion**: Therefore, fungi are classified based on three main criteria:
- Morphology of mycelium
- Mode of spore formation
- Development of fruiting bodies

### Final Answer:
Fungi are classified on the basis of:
1. Morphology of mycelium
2. Mode of spore formation
3. Development of fruiting bodies
