Coral mushrooms, otherwise known as Ramaria, are aptly named because they look similar to coral. Many species are edible but some may cause gastric upset for some people. Unfortunately the corals are often attacked by larvae, which can ruin a good meal quickly. Ramaria are very difficult to identify to species because they all become the same cardboard brown with many branches in age. If you want to try to figure them out, be sure to choose a young mushroom and collect the whole specimen.
