Answer

To answer the question, "In fungi, a lump of hyphae is referred to as:", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Fungi**: Fungi are made up of thread-like structures called hyphae. Hyphae are long, branching filaments that form the basic structural unit of a fungus.

2. **Identify the Term for a Mass of Hyphae**: When multiple hyphae come together, they form a mass. This mass is a crucial part of the fungus's vegetative structure.

3. **Recognize the Correct Term**: The term that specifically refers to a lump or mass of hyphae is "mycelium." Mycelium is the vegetative part of the fungus, consisting of a network of hyphae.

4. **Eliminate Other Options**: The other options provided (thallus, osteorium, and corpogonium) do not refer to a mass of hyphae:
- **Thallus**: Generally refers to the body of non-vascular plants or algae.
- **Osteorium**: This term is not commonly associated with fungi.
- **Corpogonium**: This term is not standard in mycology.

5. **Conclude the Answer**: Therefore, the correct answer to the question is "mycelium."

### Final Answer:
In fungi, a lump of hyphae is referred to as **mycelium**.
