The Prince

I came across this large mushroom (~8" diameter) under a mature pine tree at the arb today. My identification apps all seem fairly convinced that it's Agaricus Augustus also known as The Prince. It is apparently edible and delicious.  The website totallywilduk says: "From its firm and meaty texture to its rich, earthy and almond-like flavor, this mushroom has the power to elevate your dishes to extraordinary heights." Almost makes me tempted to try it ....., but I didn't!
