General information

Rhytisma fulvum, commonly known as Yellow Fungus, is not a species suitable for reefkeeping or any kind of aquarium hobby. It is a type of fungus that affects plants, particularly trees, and is known for causing a disease called tar spot. This disease manifests as black and yellow spots on the leaves of affected plants, which can lead to premature leaf drop and reduced photosynthesis. While it is an interesting organism from a botanical and mycological perspective, it is not relevant to the aquarium trade.
