Kuntze (1891) Lactarius turpis (also L. plumbeus or L. necator)[1] is a Eurasian species of fungus, commonly known as the ugly milk-cap in English.

It seems to collect debris on top and the gills acquire a dirty brownish stain due to discoloured milk.

This very variable mushroom demonstrates a common phenomenon in mycology as there is much disagreement over naming.

Usually found growing individually, it has a stronger olive-brown colour on its cap and stipe, with dark spots on the latter.

[6] Lactarius turpis is found naturally in Europe and Siberia, and has been introduced to Australia and New Zealand.

[citation needed] This species contains the mutagenic chemical compound necatorin,[11] so it cannot be recommended for eating.

[11] Probably due to the acrid taste, most western European authorities classify this mushroom as inedible[7] or poor.
