Panellus stipticus
Description:
Cracked and wrinkled, tan to pale orange-capped mushrooms with kidney-shaped pilei with inrolled margins. Texture is dry and fuzzy. Fairly crowded gills (with lamellulae and cross-veins) that stop short at a cream-colored stem are present. White spores are visible on the gills of some specimens. Growing in a large cluster. Panellus stipticus is a member of the Mycenaceae family and is closely related to members of the Mycena genus. It is saprobic on dead hardwoods. It is one of the unique mushrooms that has bioluminescent gills. It also holds much scientific interest as research points to it possibly having bioremediatve properties.
Habitat:
Growing on a rotting hardwood log on the side of a ridge in a mixed hardwood/coniferous forest in Northwest Georgia.
