Not meaning to sound thick but what is a geocache?
Secretly It looked like cep. the leaf stuck on made me think it was suillus spp, but I don't give IDs if the original photo doesn't have a proper display of features, because the poster shouldn't entertain eating fungi until they know more about what to look for. I do useally give advice of what the photo should include so the poster can learn what to look for, just like what COTW did.
