Stropharia hornemannii is a species of agaric fungus in the family Strophariaceae. It is found in Europe and North America, where it grows as a saprophyte on rotting conifer wood. The specific epithet hornemannii honors Danish botanist Jens Wilken Hornemann, who made the first scientifically documented collections of the species. Common names for the mushroom include luxuriant ringstalk and lacerated stropharia. It is inedible and may be poisonous. It is similar to Stropharia ambigua.

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 Stropharia hornemannii has left across the world's sequence archives.

The DNA barcodea real sequence read deposited for this species
The species whose COI barcode is most similar to this one — a quick “who is this most like”. The percentage is how much the barcode differs; it approximates, but is not, the full evolutionary tree.
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.

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.
