...possibility of confusion
...while they are both hygrophanous, K. mutabilis dries from the centre outwards (so having a lighter colour in the centre) and G. marginata dries from the edge inwards,
What is confusing me is the picture of G. marginata in the Complete Collins Guide, because it clearly shows mushrooms drying from the centre. Either the above claim in wikipedia is wrong, or it's the wrong picture in the book. Can anybody tell me which?
