Just got a DNA sequence back on a bluing Gymnopilus collected by Juno Jang in Montgomery, Alabama which confirms that Gymnopilus subspectabilis is present there. https://mushroomobserver.org/481904 Since it's in Alabama I am pretty sure this one from Georgia is also this species. https://mushroomobserver.org/152294
This is the first confirmed record of this species in the southeastern USA.
