can anybody tell me if this is honey fungus? we had a cherry tree that was dying, it was cut down, all the main roots removed as they started to grow new trees. the trunk was left to rot as it was to big to get out, we noticed mushroom like things starting to grow around the stump, we tried all things, someone said seaweed, that was great it started to make a difference, we had the trunk removed and carried on treating the lawn, removed any so called infected parts no sign of them,. great we replace the lawn in spring garden looking great!! But after the recent rain they are back. the photo is of last years problem so far not as bad but getting worse. any help gratefully received.
