This mushroom was found growing on a wood chip pile. someone has suggested it could be Gymnopilus dilepis. It certanly looks like a Gymnopilus, but i'm not sure which type. I haven't seen these colours and patterning before. It was found mid September last year in mixed woodland. Can you tell me what it is?
