This is an eye-catching organism that I saw while visiting Brecksville Reservation.
Ringless Honey Mushroom grows in clusters, often in large numbers, at the bases of trees, especially oaks. It is common in urban yards. Sometimes it looks like it’s growing right out of the ground, but it is actually growing from low stumps, roots, or other buried wood.
It is most commonly observed from September to November. It can be identified by its convex cap, which is then flattened, featuring a margin that is uplifted with age. The cap is yellow-brown to honey brown, and it lacks a ring on its stalk. There are at least 10 species of this fungus.
Ringless Honey Mushrooms exist most of the time as a network of cells (mycelium) penetrating the tissues of living trees, frequently killing their hosts by damaging the tree’s ability to transport water and nutrients. This particular species may be an exception, however, living on dead, not living, wood. When ready to reproduce, the mycelium forms mushrooms, which produce spores that are released to begin new mycelia elsewhere.
As the fruiting bodies (mushroom caps) begin to deteriorate, numerous insects swarm to them. The mushrooms provide food for a variety of small insects and other arthropods, which in turn become food for birds, salamanders, toads, and other animals.
