Please note that each and every mushroom you come across may vary in appearance to these photos.


Convex to flattened with depressed centre and even upturned edges, often becoming deformed with age. Deep purple/lilac when young fading to pale brown/tan.


Gills deep purple/lilac when young fading to pale brown/tan. Widely spaced, broad and irregular with shorter gills in-between.


Deep purple/lilac when young fading to pale brown/tan. Fibrous, usually twisted and sometimes hollow.


Purple can be white with a purple flush.


Mixed woodland, particularly with oak and beech.

Possible Confusion

When young the deep purple of the Amethyst Deceiver is quite distinctive. Caution should be taken with older specimens however as the whole mushroom can fade and look more tinged then purple. The fading can make identification less sure as there could easily be a confusion with the potentially deadly Lilac Fibrecap (Inocybe lilacina), pictured, but this mushroom has off white or grey gills whereas the Amethyst Deceiver has the same colour in the cap, gills and stem.

Spore Print

White. Globose with spines.

Taste / Smell

Mildly nutty/mushroomy and keeps its colour when cooked so a bright addition to any meal.

    Do you know if these keep well if you dehydrate them?

    1. Eric Biggane says:

      The keep very well once dried but never re-hydrate to a beautiful purple again.

        we have bone growing out bottom of our leaf litter compost hopper …..so it is safe to.leave yes? As we have a 2 year old dog?

        Also a yellow flowered similar one where roots of silver birch are?
        is that toxic for dogs please?

        Best regards

          We need to see photos of mushrooms to try and ID them. We need close ups of the cap, stem, gills and where they were growing. Send photos to [email protected]

    Thanks for the info. Tried these for the first time today and they’re pretty good eating!

  3. The Geese says:

    Found only a few of these in our local woodland and always wanted to find more; they’re delicious. Just visited a national trust woodland today and they were out in their hundreds! Mushroom stroganoff for dinner I think!

  4. Julie Houghton says:

    Today, very surprised to find such a bounty of them. Found my two biggest ever: cap of 10cm and another of 7cm. I’m going to take a crazy punt and see if I can’t make a mushroom bacon chowder with them.

  5. Mat says:

    Do you know if you can eat them raw?

    1. Eric Biggane says:

      We recommend cooking all wild mushrooms as they have not been grown in sterile conditions, also, many edible mushrooms need to be cooked before consumption as this destroys any harmful toxins.

  6. Gloria says:

    Is there any other purple mashroom … those we found today have a bit brocken rims…and some a bit pale purple…

    1. Eric Biggane says:

      There are few different purple mushrooms, Inocybe lilacina, a poisonous mushroom, can look similar to Amethyst Deceivers but has grey rather than purple gills. Some of the Cortinarius mushrooms are purple but they are generally bigger and not known to be toxic but are inedible due their bitter taste. There are some other rarer purple mushrooms but as long as you stick to our identification for amethyst deceivers, you will be safe.
