This is a vertical cross-section photograph of a single Spotted Toughshank (Rhodocollybia maculata) mushroom lying on a bed of dry leaves and twigs. The mushroom has been sliced vertically through its center to reveal its internal structure.
**Mushroom Characteristics:**
The gills, which are the underside of the cap, are pale white in color with brown spots that appear to be remnants from the spores once attached to them.
The stem, or stipe, is long and thin with a slight curve in it. The bottom of the mushroom where the cap meets the stem has a small amount of mycelium (the vegetative part of a fungus) still attached. The top of the stem where it meets the cap appears to be covered in some sort of brown material that may be the remnants of its original growth.
**Background:**
The bed of dry leaves and twigs, which are most likely pine needles due to their color, provides a naturalistic background for the mushroom. – AI vision
