Hahaha ! I had the same thoughts, and what's more, several of my reference experts in terms of mushrooms hadn't replied... and then I ended up simply eating my parasol zwam (beautiful name btw !) with a little garlic and butter :)
I know from speaking with my brother that colors of the photographies can often be quite confusing, but in the end, as you and every people interested in mushrooms, no risk is allowed !
Many warm hugs from the Normandy dear Vincent !
