Explanation

To determine which statement is incorrect, we will analyze each option provided in the question step by step.

### Step 1: Analyze the first statement
- The first statement claims that "Easts have filamentous bodies with long, thread-like hyphae."
- This statement is incorrect because yeasts are unicellular fungi and do not have filamentous structures or hyphae. Instead, they exist as single cells.

### Step 2: Analyze the second statement
- The second statement mentions that "Morals and truffles are edible delicacies."
- This statement is correct. Morals and truffles are indeed edible fungi and are considered delicacies in various cuisines.

### Step 3: Analyze the third statement
- The third statement states that "Claviceps is a source of many alkaloids and LSD."
- This statement is also correct. Claviceps purpurea, for example, is known for producing ergot alkaloids, which include LSD.

### Step 4: Analyze the fourth statement
- The fourth statement says that "Conidia are produced exogenously and ascospores endogenously."
- This statement is correct. Conidia are asexual spores produced externally (exogenously), while ascospores are produced within a sac-like structure (ascus), making them endogenous.

### Conclusion
After analyzing all the statements, we find that the first statement is incorrect. Therefore, the answer to the question is:

**The incorrect statement is option number one: "Easts have filamentous bodies with long, thread-like hyphae."**
