Can identify this tree fungus and predict the likely outcome for the host tree? #879309
Asked July 29, 2024, 5:17 PM EDT
The attached photos show what I assume is a fungus growing at the base of an ornamental cherry tree in our yard. The tree overhangs a portion of our roof and I’m concerned if it’s diseased and dying, it will quickly become a safety concern. What can you tell me about what you see? Is there anything I can do for the tree? It’s is in a well-drained area that has not been damp, other than occasional watering, since late spring. Thank you

That looks like a slime mold, which are fungus like organisms (but not true fungi, they are actually plasmodium, which are similar to amoeba). Slime molds are initially yellow to red in color but fade to a tan or brown color as they dry out. They are not known to be a danger to humans, animals, or plants. The slime mold in the photo could be False puffball (Enteridium lycoperdon), but I am not certain. There is a Facebook group that is dedicated to identifying slime molds, you could submit a photo to them for proper identification: https://www.facebook.com/groups/SlimeMold.
