Morel mushrooms grow in all 50 states, as they are found in various regions across the United States. They are mycorrhizal with particular tree species in most cases, meaning they form a symbiotic relationship with the roots of certain trees. Morels are completely hollow, which is a distinctive characteristic of this type of mushroom. They are elusive and blend in with their surroundings, making them difficult to spot. While morels can be found in the wild, they have also been successfully grown indoors. Although some mushrooms can cause hallucinations, morels do not have this effect. Lastly, the statement "are my favorite edible mushroom" is a personal opinion and not a factual explanation.
