Also wanted to mention that this group of mushrooms would create a small fog of spores late at night that surrounded them. The spores would fall and create a greyish area blanketing the area around them at nearly twice the diameter of the mushroom. It was a bit surreal to view this with a flashlight. Just wanted to mention it for those that might want see what their giant polypores are up to on a dark windless night. 🙂

Thank you for all the replies. I don’t think it grew much further, so it topped out at about 2′ diameter before turning brown. https://postimg.org/image/jwmwf0qev/ Now I have some alien grass that I’m trying to identify and have since posted it in the grass section. Although it’s possibly not even grass but rather a type of fungus – but it looks more like plastic or something synthetic than either of those.

Yours looks like several mushroom species: _Black-staining polypore (Meripilus sumstinei). _ Turkey tail (Trametes versicolor). You should try the experts at the MUSHROOM CLUB OF GEORGIA from the link below to help with its correct ID. Best wishes! http://www.gamushroomclub.org/
