About this fungus

Big Smoky Bracket is a fungus in the Phanerochaetaceae family. Its habitat and field characteristics are summarised below.

Broad, thick buff brackets with a pale smoky pore surface beneath.

What to check

Cut a bracket and look for thick pale flesh, a distinct dark line above the tube layer and small round pores.

Variation

Young margins can be nearly white; older caps become buff, grey-brown or algae-stained.

Lookalikes

Bjerkandera adusta is normally thinner and has a darker grey pore layer. Trametes species lack the same smoky context line.

Habitat and range

A white-rot decomposer of broadleaf wood across temperate regions, often on willow and poplar.

Food safety

Inedible.

Weather response

A repeatable weather association was found in the records, alongside the usual seasonal pattern.

Higher or lower ground?

Records tended to come from lower ground relative to other fungal records in the study.

These are patterns in recorded observations, not rules, forecasts or identification evidence. Local conditions and recording patterns can affect the findings.
