Brown Roll Rim
This common and deadly poisonous mushroom is thankfully easy to identify.
|Common Names||Brown Roll Rim, Poison Pax, Common Roll Rim|
|Scientific Name||Paxillus involutus|
|Average Mushroom height (CM)||8|
|Average Cap width (CM)||20|
Flattened with a slight depression towards the middle with the edges always rolling under to the gills. Rusty brown with a slimy cap when wet.
A distinctive mushroom with some variability. After recent DNA studies mycologists have now divided this mushroom in a group of species, but beside looking quite similar for foraging purposes all Roll Rim species (Paxillus sp.) should be treated as poisonous.
The Velvet Roll Rim (Tapinella atrotomentosa) is similar but grows on wood and it’s also not considered safe for consumption.
At a first glance it could sometimes resemble one of the Milkcaps (Lactarius) but unlike those it doesn’t exude any milk from the gills.
Burnt brown. Ellipsoid.
Taste / Smell
Do not taste any part of this mushroom.
This mushroom contains a toxin that can be neutralised by lengthy boiling and discarding the water several times but this does not remove another toxin that can build up in the body over time and eventually lead to a rather nasty death. It is eaten in certain parts of Eastern Europe but still leads to deaths every year there. Definitely a mushroom to avoid.
Despite having gills this mushroom is closer related to Boletes (mushrooms with pores) than other gilled mushrooms.
