Russula acrifolia is a species of mushroom. Its cap is coloured grey to blackish-grey; the cap becomes red when it is injured, but then turns blackish-gray. It is edible and described as having an acrid taste. It grows on rich soils.

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 acrifolia has left across the world's sequence archives.

Where the DNA of Russula acrifolia 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.
