Of all the photos I’ve taken of fungi this season, I rate this as the best. Shame I can’t identify it with absolute certainty. It’s a parasol, that’s all I will say.
Why is it ‘perfection’? Cos it’s not yet nibbled by bird, insert nor squirrel, and no tree has dropped debris upon it, and the rain hasn’t spoiled it. I’m guessing it’s newly risen that day.
