The image features two photographs of mushrooms growing on the bark of a standing dry oak tree. The top photograph displays the mushrooms under regular daylight conditions, while the bottom photograph shows them illuminated by a blacklight emitting UV-A radiation at 365 nm.

In both images, three mushroom caps are visible in the center area. The mushrooms have brownish-red edges with lighter centers and appear to be growing from the bark of the tree. The bark is grayish-beige, covered in lichen, and features dark spots where water has seeped into the cracks.

The top photograph shows the mushrooms under regular daylight conditions, while the bottom image reveals them fluorescing when exposed to UV-A radiation at 365 nm. This suggests that the mushrooms are capable of absorbing UV light and emitting it back out in a longer wavelength.

Overall, the image provides a clear visual representation of the mushrooms' growth on the oak tree bark and highlights their unique ability to absorb and emit UV radiation. – AI vision
