Agaricus semotus is a woodland mushroom of the fungus order Agaricales. It, like many of its relatives, can be found spread throughout wooded, moist areas in the southern United States, and has been found in areas ranging from California to Florida; it is also indigenous to Great Britain and Europe. A. semotus has also been collected in New Zealand.Mitchell AD, Walter M. (1999). "Species of Agaricus occurring in New Zealand". New Zealand Journal of Botany 37(4): 715–25. Although various authors disagree about its edibility, its modest size prevents it from being a significant source of nutrition.

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 Agaricus semotus has left across the world's sequence archives.

07Deep time~13.2 Ma lineage
How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

DNA clock origin13.2 Ma TimeTree
When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

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.
