Lumpy Bracket
Trametes gibbosaAlso known as Beech Bracket
Lumpy brackets form tough, semicircular shelves that anchor firmly to decaying deciduous wood, driving the white-rot decay process by breaking down tough lignin and cellulose. The pale velvety upper surface typically develops distinctive humps near the base, frequently acquiring a vivid green coating of epiphytic microalgae as it ages. The underside features unusual elongated, maze-like pore slits that release millions of windborne spores while harboring specialized fungivorous beetle larvae.

- Very high
- Why interaction risk is low
- Many edible mushrooms have toxic look-alikes; never eat wild fungi based on app identification alone.
Responsible observation
- Pore inspection: Check the underside to observe the characteristic elongated, slot-like pores.
- Substrate searching: Look on old beech stumps and fallen hardwood trunks in damp woodlands.
