Gilled mushrooms
Woolly milkcap
Lactarius torminosus · also known as: Bearded milkcap, Pink-fringed milkcap
Poisonous
We classify it as POISONOUS (the safer class). Raw or badly prepared it causes nausea, vomiting and diarrhoea. In Scandinavia, Russia and Ukraine it is eaten after repeated soaking, boiling with the water discarded, and lacto-fermenting – which is why grzyby.pl lists it as “inedible or edible after processing”, while the regional sanitary-epidemiological station (WSSE) and most European sources list it as poisonous. We do not recommend picking it. In 2025 the Polish Mycological Society (PTMyk) committee recommended the name “mleczaj żółtoobrączkowy”.
