which of the following is true for mycorrhiza with fungal hyphae forming wooly covering and hartig net?

Options

A. Ectdomycorrhiza with Glomus as fungal partner
B. Endomycorrhiza with Boletus as fungal partner
C. Ectdomycorrhiza with Boletus as fungal partner
D. Endomycorrhiza with Glomus as fungal partner

Answer

To solve the question regarding mycorrhiza with fungal hyphae forming a woolly covering and Hartig net, we will analyze the options step by step.

### Step-by-Step Solution:

1. **Understanding Mycorrhiza**: Mycorrhiza refers to the symbiotic association between fungi and the roots of higher plants. This relationship is beneficial for both the plant and the fungus.

2. **Identifying Key Features**: The question mentions two specific features:
- Woolly covering (also known as a mantle)
- Hartig net

These features are characteristic of ectomycorrhizae, which are a type of mycorrhiza where the fungal hyphae form a dense mantle around the root and extend into the root cortex, forming the Hartig net.

3. **Analyzing the Options**:
- **Option A**: Ectomycorrhiza with Glomus as a fungal partner. This is incorrect because Glomus is typically associated with endomycorrhizae, not ectomycorrhizae.
- **Option B**: Endomycorrhiza with Boletus as a fungal partner. This is incorrect because Boletus is a genus of fungi that forms ectomycorrhizae, not endomycorrhizae.
- **Option C**: Ectomycorrhiza with Boletus as a fungal partner. This is correct because Boletus is known to form ectomycorrhizal associations and exhibits both the woolly covering and Hartig net.
- **Option D**: Endomycorrhiza with Glomus as a fungal partner. This is incorrect because Glomus is indeed associated with endomycorrhizae, but the features mentioned do not apply here.

4. **Conclusion**: Based on the analysis, the correct answer is **Option C: Ectomycorrhiza with Boletus as a fungal partner**.
