Its a known as a Whiticus Priveligesum. It is typically found growing in suburban climates and environments, most often on manicured lawns. It has a unique defense mechanism it uses against its many natural enemies. When attacked, it relies on other blue colored fungus to defend itself. If the blue fungus cannot help it will gather in clusters and totally fuck up the invading fungii. Some sources claim its dying out in middle North America but it's also been reported it appears it may be making a comback.....in a big way. It normally comes in full bloom around early November.
It does look like a coral mushroom which are not typically considered choice or even edible.
But being under an oak it could be an immature Hen of the Woods (Grifola frondosa) which is a choice edible. Google it and see what develops as it grows. If it is do not let it go too far as they do get tough.
It’s weird it is close to a few of the things mentioned but not quite... it grew quick when I first noticed it I thought it was a white puff, their delicious cut like bread and fried in a skillet with butter and garlic. I was disappointed to see that it wasn’t
It looks like a Crown Coral Mushroom too me. Very edible, tastes like crap and very low nutrition.
Coral mushrooms usually have longer looking vents but they can differ widely. Not common in this area but I dont know what else it could be.
Go to "Learn Your Land" on Youtube and ask him. Hes from the area....Northeast.....and is extremly versed in fungus.
Chicken of the woods is orange to yellow. Hen of the woods is usually grey to brown and they can get huge. I collected 3 of them a couple years ago that totaled about 60lbs worth. Chicken of the woods will be founbd growing on dead stumps or fallen trees. Hens will always be found at or near the base of a tree. Almost always oak trees.
It does look like a coral but it seems a bit larger than most I have seen.
The vast majority of mushrooms are technically edible but a large percent of those are not considered edible due to flavour or texture. In reality it is only a small percentage of them that are poisonous with most of those not lethal.
