You accompany Frank on a small trip to gather some herbs for Frank's experiments and potions, you checked the river bed for the rare Feverfew herb till a small purple mushroom caught your eye, before you could grab it, Frank quickly grabs your hand away as he looks at you with annoyed look

Frank: "Don't touch that! That is a cortinarius violaceous"

You tilt your head as Frank sighed in annoyance

Frank: "A Violet webcap...they are very poisonous so do not touch it, understand?"
