C. Claviceps is a source of many alkaloids and LSD.
D. Conidia are produced exogenously and ascospores endogenously.

Explanation

To determine which of the statements is incorrect, we will analyze each statement provided in the question.

### Step-by-Step Solution:

1. **Statement 1: "Yeast have filamentous bodies with long thread-like hyphae."**
- Yeast belongs to the group Ascomycetes and is primarily unicellular. Unlike many fungi that have filamentous structures called hyphae, yeast does not have long thread-like hyphae. Therefore, this statement is incorrect.

2. **Statement 2: "Morals and truffles are edible delicacies."**
- Morals and truffles are indeed edible fungi that belong to the Ascomycetes group. This statement is correct.

3. **Statement 3: "Claviceps is a source of many alkaloids and LSD."**
- Claviceps is known to produce alkaloids, including LSD (lysergic acid diethylamide), which is used in medicine. This statement is also correct.

4. **Statement 4: "Conidia are produced exogenously."**
- Conidia are indeed produced exogenously on specialized hyphae called conidiophores. This statement is correct.

### Conclusion:
The incorrect statement is **Statement 1**: "Yeast have filamentous bodies with long thread-like hyphae."
