This is called a “shrump”; it is a hump in the duff caused by a mushroom coming up from underneath. Just like a Christmas present, you can’t tell what’s in there until you open it.
Inside the shrump is Russula brevipes.
What on Earth is THAT? Well, believe it or not, this too used to be Russula brevipes. It was attacked by another fungus that is parasitic on other mushrooms – Hypomyces lactiflourum.
Hypomyces lactiflourum is not always so “mushroomy” looking. Many times the host is so deformed you can hardly tell what it was. In this one you can even still see where the gills are.
