Pseudoplectania nigrella, commonly known as the ebony cup, the black false plectania, or the hairy black cup, is a species of fungi in the family Sarcosomataceae. The fruit bodies of this saprobic fungus are small blackish cups, typically up to 2 cm broad, that grow in groups on soil, often amongst pine needles and short grass near coniferous trees. Pseudoplectania nigrella has a worldwide distribution, and has been found in North America, the Caribbean, Britain, Europe, India, Madagascar, New Zealand, and Japan. The fungus produces a unique chemical compound, plectasin, that has attracted research interest for its ability to inhibit the growth of the common human pathogenic bacterium Streptococcus pneumoniae.

The complete instruction manualPseudoplectania nigrella 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.
Genome sizehow big the whole instruction manual is
Genome size37 525 000 bp
Measured in base pairs (bp) — the individual letters of DNA (human ≈ 3.2 Gb, a bacterium a few million). The chart places this genome on a logarithmic scale — each step to the right is ten times bigger — among reference organisms. Across species a bigger genome loosely tracks with larger cells, slower growth and lower-energy lifestyles (powered flight favours small genomes) — yet it does not imply more genes or a more advanced organism (the long-standing C-value paradox).

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.
