Firmly located in Auriculariaceae, this genus of about 9 species worldwide is clearly rather unusual for a crust. It does have this very recognisable appearance of pinkish colour with a white slightly frilly edge, developing blunt scattered spines and outgrowths, and a characteristic physical response to rubbing of blushing, as seen here.
Its the second time I've ever seen this crust, both being in this one week. No doubt many more to come.
By contrast, Corticium roseum has no white border, is pleated rather than spined or thrown up, and is a more consistent pink, which bleeds somewhat carmine when cut.
