I need help identifying a perculiar species of mushroom found in my yard today. Color is orange-yellow, around 3-4 inches total radius, its a cluster of tiny to medium mushrooms. They were found near an oak tree. Location is southern Georgia, USa.
These could be specimens of Omphalotus Illudens based on the orange/yellow color, the time of the year, their association with decaying wood (an oak in this case) and your location (eastern North America)
