👉 A viridaria is a type of fungus that is known for its bright red color and often associated with the appearance of fungi that have been exposed to sunlight. This condition can occur in many different types of fungi, but it is most commonly found in certain types of mushrooms and other fungi that are exposed to direct sunlight. The bright red color of these fungi suggests their rapid growth and reproduction, which may be a result of the fungus's ability to absorb light energy from the sun.
