Atrichum tenellum, also known as the slender smoothcap, is a species of moss belonging to the family Polytrichaceae. It is red listed in Iceland as a critically endangered (CR) species. In Iceland, it is only found in two geothermal areas.Náttúrufræðistofnun Íslands [Icelandic Institute of Natural History] (1996). Válisti 1: Plöntur. (in Icelandic) Reykjavík: Náttúrufræðistofnun Íslands.

06Genome at a glanceCCDB
The complete instruction manualAtrichum tenellum carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants. Click any value below to see the underlying records and sources.

09Environmental DNA6 detections
Where the DNA of Atrichum tenellum 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.
