Russula alnetorum is a species of mushroom in the genus Russula. The fruiting bodies are found growing on the ground in the vicinity of alder trees with which this fungus has a symbiotic relationship. The cap is purple and the gills and stem white, darkening with age.

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 Russula alnetorum has left across the world's sequence archives.

Where the DNA of Russula alnetorum 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.
