The mushroom shown is a young Tawny Grisette, Amanita fulva. It’s in the same family as the deadly poisonous Death Cap (A. phalloides) and Destroying Angel (A. virosa), and the hallucinogenic Fly Agaric (A. muscaria). Although it is said to be edible if well cooked, it still causes a reaction in some people so I’ve never been tempted to try it, personally.
The glorious mass of silvery blue-green is Reindeer Lichen, Cladonia portentosa. It has no roots so it dehydrates quite easily in dry weather, becoming soft and luxuriant again when the weather is damp. We’ve had a dry spell lately but it still looked so soft and welcoming that I was tempted to lie down on it for a nap. 😉
