Amanita citrina (synonym Amanita mappa), commonly known as the false death cap or citron amanita, is a basidiomycotic mushroom, one of many in the genus Amanita. It grows in silicate soil in the summer and autumn months. It bears a pale yellow or sometimes white cap, with white stem, ring and volva. Though not deadly, it is inedible and often confused for the lethal death cap (Amanita phalloides).

Where the DNA of Amanita citrina 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.
