Spathularia flavida, commonly known as the yellow earth tongue, the yellow fan, or the fairy fan, is an ascomycete fungus found in coniferous forests of Asia, Europe and North America. It produces a small, fan- or spoon-shaped fruit body with a flat, wavy or lobed cream to yellow colored "head" raised on a white to cream stalk. The height is usually approximately 2 –, and up to 8 cm. The fungus fruits on the ground in mosses, forest duff or humus, and fruit bodies may occur singly, in large groups, or in fairy rings. The spores produced by the fungus are needle-like, and up to 95 um long. Several varieties have been described that differ largely in their microscopic characteristics. S. flavida has been described by authorities variously as inedible, of unknown edibility, or edible but tough.

05DNA & barcoding17 specimens
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 Spathularia flavida has left across the world's sequence archives.

The complete instruction manualSpathularia flavida 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 size36 670 000 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.
