D. Mycellium

Answer

To answer the question about the thalloid body of a slime mould (Myxomycetes), we can follow these steps:

### Step-by-Step Solution:

1. **Understand what slime molds are**: Slime molds, also known as Myxomycetes, are unique organisms that exhibit characteristics of both fungi and animals. They are often found in decaying vegetation and are saprophytic, meaning they feed on dead organic matter.

2. **Identify the structure of slime molds**: The body of slime molds is not structured like typical fungi. Instead, they have a thalloid body, which is a mass of protoplasm that is not divided into individual cells.

3. **Differentiate between types of slime molds**: Slime molds can be categorized into two types: acellular (plasmodial) and cellular. The acellular slime molds have a thalloid body that is multinucleate and lacks cell walls.

4. **Define the thalloid body of acellular slime molds**: In acellular slime molds, the thalloid body is specifically referred to as "plasmodium." This structure is a large, multinucleate mass of cytoplasm that can move and grow, and it is covered by a slimy layer.

5. **Select the correct answer**: Given the options provided, the correct term for the thalloid body of a slime mould (Myxomycetes) is "plasmodium."

### Final Answer:
The thalloid body of a slime mould (Myxomycetes) is known as **plasmodium**.
