Lactarius acris is a member of the large milk-cap genus Lactarius in the order Russulales. Found in Europe, the species was described in 1821 by British botanist Samuel Frederick Gray. It is considered unpalatable due to its strong flavour, but the bitterness can be removed by repeated washing and salting.

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Lactarius acris has left across the world's sequence archives.

Where the DNA of Lactarius acris was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
