Phyllotopsis nidulans, commonly known as the mock oyster or the orange oyster, is a species of fungus in the family Tricholomataceae, and the type species of the genus Phyllotopsis. It is widely dispersed in temperate zones of the Northern Hemisphere, where it grows on decaying wood. The fungus fruit body consists of a fan-shaped, light orange fuzzy cap up to 8 cm wide that grows singly or in overlapping clusters. On the cap underside are crowded orange gills. Mock oyster mushrooms have a strong, unpleasant odor, and are regarded as inedible though nonpoisonous.

Compounds documented for Phyllotopsis nidulans across natural-product and food-composition databases — not just the ~150 nutrients on a classic label ("nutritional dark matter").
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 Phyllotopsis nidulans has left across the world's sequence archives.

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.
