2. **Identifying the Options**: The options given are:
- Fibrosclerides
- Macrosclerides
- Osteosclerides
- Brachysclerides

3. **Defining Sclerides**: Sclerides are a type of sclerenchyma cells that are characterized by their thickened, lignified cell walls. They are typically found in various plant tissues and contribute to the hardness of certain plant parts.

4. **Analyzing the Options**:
- **Fibrosclerides**: These are elongated and fiber-like, not typically referred to as stone cells.
- **Macrosclerides**: These are larger sclerides but do not specifically denote stone cells.
- **Osteosclerides**: These are bone-like sclerides but are not specifically known as stone cells.
- **Brachysclerides**: These are short, rounded sclerides that are specifically referred to as stone cells.

5. **Conclusion**: Based on the definitions and characteristics of the different types of sclerides, Brachysclerides are specifically known as stone cells.
