The image shows a close-up view of a pale brown resupinate polypore mushroom, specifically Xylodon flaviporus, growing on the underside of an oak (possibly) log in Lick Creek Park.
The mushrooms are light cream to yellowish-brown and have many tiny pores that can be seen with the naked eye. The background is dark gray or black. There appear to be some small twigs or branches scattered around the bottom part of the image.
The overall atmosphere suggests a late spring morning in a forested area, likely during early April when these mushrooms would typically fruit. – AI vision
