Clavariadelphus pistillaris is a rare species of mushroom of the family Gomphaceae native to Europe and North America. It grows during summer and autumn almost exclusively in beech forest on calcareous soil on litter and woodchips. The mat and wrinkled fruiting body has the shape of a club with a rounded top. Its length varies between 10 cm and 30 cm and its width between 1 cm and 5 cm. The skin is red brown to ocher red, sometimes cinnamon brown with a lilac tint, turning brown when damaged. The spongy flesh is white. The spore print is pale yellow. It has a weak, but pleasant scent. Through its appearance it could be mistaken for Clavariadelphus truncatus, a species found in coniferous mountainous forests. The western North American variety is known as C. occidentalis.

The complete instruction manualClavariadelphus pistillaris 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 size≈265 463 582 bp assembly estimate
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).

Sequencing statusassembly quality — how far to trust these numbers
Assembly level tells you how finished the sequence is — from fragmented contigs, through scaffolds, up to a full chromosome-level assembly. BUSCO % estimates completeness: the share of genes expected to be present that were actually found. These describe the data quality, not the organism.

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.
