Armando , It is a Fungi, "Macrolepiota rhacodes var.Hortensis." Now there's a mouthful! Rhacodes means ragged, as you can see. Here in UK it is known as Shaggy Parasol Mushroom. And guess what? it used to grow at the bottom of my garden under a Fir tree, but the last couple of years there has been no trace.When young they look like drum sticks. I'll post the picture of the young, when I find it among my transparencies..........warm regards Rita
