Amanita ceciliae, commonly called snakeskin grisette, strangulated amanita, and the Cecilia's ringless amanita, is a basidiomycete fungus in the genus Amanita. First described in 1854 by Miles Joseph Berkeley and Christopher Edmund Broome, it was given its current name by Cornelis Bas in 1984. It is characterized by bearing a large fruit body with a brown cap 5 – across. The cap has charcoal-grey patches, which are easily removable. The stipe is 7 – long, white in colour, and there is no ring on it. It is slightly tapered to the top, and has irregular cottony bands girdling the base. The universal veil is grey. Spores are white, spherical in shape, non-amyloid, and measure 10.2–11.7 micrometres. The mushrooms are considered edible, but field guides typically advise caution in selecting them for consumption, due to risks of confusion with similar toxic species. A. ceciliae is found in woods throughout Europe and North America, where it fruits during summer and autumn.

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 Amanita ceciliae has left across the world's sequence archives.

Where the DNA of Amanita ceciliae 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.
