Underside of a polypore mushroom Ganoderma ...

The image presents a comparison of the underside of a polypore mushroom, specifically Ganoderma sessile, under two different lighting conditions: regular daylight and UV-A blacklight illumination.

**Daylight Image:**

* The top half of the image shows the underside of the mushroom in natural daylight.
* The surface appears dull and light brown with some darker spots scattered throughout.
* There are no visible features or patterns on the surface that stand out under regular lighting conditions.

**UV-A Blacklight Image:**

* The bottom half of the image displays the same area illuminated by a 365 nm UV-A blacklight.
* The entire surface is now brightly lit up, revealing intricate details and patterns not visible in daylight.
* The color has changed dramatically, turning pinkish-red with some blue undertones.
* A network of fine lines and dots covers the surface, giving it a textured appearance.

**Comparison:**

* The UV-A blacklight reveals features that are invisible or poorly visible under regular lighting conditions.
* The change in color is striking, transforming the dull brown to a vibrant pinkish-red hue with blue undertones.
* The fine lines and dots on the surface suggest a complex structure beneath the surface of the mushroom.

**Conclusion:**

The image highlights the unique properties of Ganoderma sessile when exposed to UV-A blacklight. This phenomenon allows for the observation of details that would otherwise remain hidden, providing valuable insights into the mushroom's morphology and potentially its biological functions or interactions with its environment. – AI vision
