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


Convex at first looking a little like a Puff Ball then opening and flattening. Olive/green sometimes with a flush of tan or yellow. Slimy when wet but still looking shiny when dry.


Gills white/cream, free of the stem. Crowded.


White with a  bulbous base and surrounded by a thin veil (volva) which is sack-like at ground height, tapering slightly towards the cap. The top of the volva will often be found attached to the stem more than halfway up, looking like a skirt.


Has obvious striations under the skirt sometimes visible on top.


A very obvious deep volva.




Most mixed woodland, particularly with oak and other deciduous trees.

Spore Print

White. Ellipsoid to subglobose. You should scrape your spores into a small pile to get an accurate spore colour.

Taste / Smell

DO NOT try any part of this mushroom.


Uncommon but can become more frequent some years when the conditions are right.

Other Facts

Although causing the most fatalities this deadly fungus has no known antidote. The symptoms start several hours after ingestion with severe vomiting, diarrhoea and abdominal pains and can last for a few days; this is followed by what seems to be a full recovery for a few days but ending in death from kidney and liver failure. The main poison, alpha amanatin, kills liver cells and passes through the kidneys to be recirculated and cause more damage.

    Is there a litmus type paper that will identify the moisture of poisonous mushrooms?
