When a portion of fungal mycelium is used in the formation of reproductive structure, the organism is called as

Options

A. eucarpic
B. ascarpic
C. holocarpic
D. none of these

Answer

To solve the question "When a portion of fungal mycelium is used in the formation of reproductive structure, the organism is called as", we can follow these steps:

### Step 1: Understand the Question
The question is asking about a specific type of fungal organism that uses a portion of its mycelium to form reproductive structures.

### Step 2: Analyze the Options
We have four options to consider:
1. Eukarpic
2. Escarpic
3. Holocarpic
4. None of these

### Step 3: Define Each Term
- **Eukarpic**: This term refers to fungi where the thallus (body) is differentiated into vegetative and reproductive parts. This means that a portion of the mycelium is indeed used to form reproductive structures.
- **Escarpic**: This term is not commonly used in mycology and does not describe a type of fungal reproduction.
- **Holocarpic**: In holocarpic fungi, the entire thallus is converted into a reproductive structure, meaning it does not retain a vegetative part.
- **None of these**: This option suggests that none of the previous terms are correct, which we will evaluate after analyzing the other options.

### Step 4: Identify the Correct Answer
From the definitions:
- Eukarpic fungi are the ones where a part of the mycelium is used for reproduction, making it the correct answer.
- Escarpic and Holocarpic do not fit the description provided in the question.
- Therefore, "None of these" is also incorrect.

### Conclusion
The correct answer is **Eukarpic**.
