Liberty Cap Mushroom

Liberty Cap Mushroom


One of the most famous magic mushrooms out there, second only to the Fly Agaric, the Liberty Cap is common in Britain and Ireland throughout the autumn season. A growing body of research is showing that psilocybin, the main psychoactive compound in magic mushrooms, has potential in treating psychological disorders like depression, addiction and PTSD.

Foraging Season

September to November



Ranging from 0.5 to 2cm in diameter, the cream-coloured caps have striations that become more pronounced with age and in dry weather. The caps usually have a distinct pimple on the top.




The gills of the LIberty cap are grey with a slight earthy tinge. As the mushroom matures or gets wet they can darken. 




The stem of the Liberty cap is a mixture of cream, brown and auburn in colour. A key to knowing that you have found a liberty cap is the stem will spring back up when moved or bent slightly. 




The Liberty Cap is famously known to grow in grassy areas like fields, golf courses or on the side of hills. If you are in a field you can look around tufts of grass or around where other mushrooms are. Sometimes you need to just stop and let your eyes adjust to the landscape and you will begin to spot them all around you.
