Amanita flavoconia, commonly known as yellow patches, yellow wart, orange amanita, yellow-dust amanita or the American yellow dust amanita, is a species of mushroom in the family Amanitaceae. It has an orangish-yellow cap with yellowish-orange patches or warts, a yellowish-orange annulus, and a white to orange stem. Common and widespread throughout eastern North America, Amanita flavoconia grows on the ground in broad-leaved and mixed forests, especially in mycorrhizal association with hemlock.

Where the DNA of Amanita flavoconia 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.
