Options

A. Yeast have filamentous bodies with long thread-like hyphae.
B. Morels and truffles are edible delicacies.
C. Claviceps is a source of many alkaloids and LSD
D. Conidia are produced exogenously and ascospores endogenously.

Answer

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

### Step 1: Analyze the first statement
**Statement:** Yeasts have filamentous bodies with long thread-like hyphae.
**Analysis:** This statement is incorrect. Yeasts are unicellular fungi and do not have filamentous structures or hyphae. Instead, they exist as single cells.

### Step 2: Analyze the second statement
**Statement:** Morels and truffles are edible delicacies.
**Analysis:** This statement is correct. Morels and truffles are indeed edible mushrooms and are considered delicacies due to their unique flavors and rarity.

### Step 3: Analyze the third statement
**Statement:** Claviceps is a source of many alkaloids and LSD.
**Analysis:** This statement is correct. Claviceps, particularly Claviceps purpurea, is known for producing alkaloids, including LSD (lysergic acid diethylamide).

### Step 4: Analyze the fourth statement
**Statement:** Conidia are produced exogenously and ascospores endogenously.
**Analysis:** This statement is also correct. Conidia are asexual spores that are formed externally (exogenously), while ascospores are formed internally (endogenously) within a sac-like structure called an ascus.

### Conclusion
After analyzing all the statements, the incorrect statement is: **Yeasts have filamentous bodies with long thread-like hyphae.**

### Final Answer
The correct option for the question is that the statement "Yeasts have filamentous bodies with long thread-like hyphae" is incorrect.
