Not a lot of these green mushrooms about. I think it is because it changes color as it ages. Here are two shots of this species. You can see why it is called Parrot Waxy Cap, Hygrocybe psittacina. ( photo / image / picture from Kildale's Garden ) ( photo / image / picture from Kildale's Garden )
I prefer it's colouring before it matures. As you say green mushrooms are so unusual that I think that's what attracts me to it.
