Retiboletus griseus, commonly known as the gray bolete, is a species of bolete fungus in the family Boletaceae. The species was first described scientifically in 1878 by American botanist Charles Christopher Frost. It was transferred to Retiboletus in 2002.

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 Retiboletus griseus has left across the world's sequence archives.

09Environmental DNA1 detections
Where the DNA of Retiboletus griseus 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.
