Leucoagaricus americanus is a mushroom in the genus Leucoagaricus, native to North America. It was first described by Charles Horton Peck, an American mycologist of the 19th and early 20th centuries, in 1869. It is widely distributed in North America, though more common east of the Rocky Mountains; it is saprobic, and grows on sawdust, on wood chips, on stumps, and on the ground.Kuo, M. (2005, October). Leucoagaricus americanus. Retrieved from the MushroomExpert.Com Web site: http://www.mushroomexpert.com/leucoagaricus_americanus.html It is not consumable; may cause vomiting, diarrhea and stomach pain.

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 Leucoagaricus americanus has left across the world's sequence archives.

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.
