大名Paxillus involutus，以前认为无毒。其实是致命慢性毒，引起体内产生自身免疫病，导致死亡，可能长达数年无症状，再次食用后发病死亡。Previously considered edible and eaten widely in Eastern and Central Europe, it has since been found to be dangerously poisonous, after being responsible for the death of German mycologist Julius Schäffer in 1944. It had been recognized as causing gastric upsets when eaten raw, but was more recently found to cause potentially fatal autoimmune hemolysis, even in those who had consumed the mushroom for years without any other ill effects. An antigen in the mushroom triggers the immune system to attack red blood cells. Serious and commonly fatal complications include acute renal failure, shock, acute respiratory failure, and disseminated intravascular coagulation. 边缘下卷，又称 brown roll-rim，肉黄色。孢子印铁锈色。

近亲种Paxillus obscurisporus，可能有类似毒性。尚不清楚。
