The image depicts a close-up of a hydnoid fungus growing on the underside of an oak leaf that is attached to a log. The fungus has grown outward from the leaf and appears to have been breaking down the wood beneath it as well.
The fungus grows in small, rounded teeth-like structures. It has white mycelium surrounding its fruit bodies, giving it a fuzzy appearance. The fungus covers the entire bottom of the leaf and some of the log.
It is unclear what type of hydnoid fungus this might be or whether it is edible. Some hydnoids are considered to be choice edibles by mushroom enthusiasts, while others are considered inedible due to their high cellulose content.
Hydnoid fungi generally grow on decaying wood and can often be found growing on logs and stumps that have been sitting for a long time. – AI vision
