What is another word for felt fungus?
Pronunciation: [fˈɛlt fˈʌŋɡəs] (IPA) 
Felt fungus, also known as tar-spot fungus or black-spot fungus, is a common plant disease caused by the fungus Rhytisma acerinum. This fungus infects trees, particularly maple, and forms black, tar-like spots on the leaves. To describe this fungal disease, several synonyms can be used, such as black tar disease, maple black spot, leaf fungus, or black leaf disease. These synonyms illustrate the appearance of the disease and the tree affected. Felt fungus can harm the photosynthesis processes in the leaves and eventually lead to leaf drop, which can affect the tree's overall health and sustainability. Therefore, it's essential to recognize and treat felt fungus early on to prevent further damage.
