sap. Widely across lowland England, but absent from far west; only Denbighshire in

Quedius xanthopus Erichson - Nationally Scarce B. Under bark in decaying timber and in
the fruiting bodies of fungi growing from it. A wide variety of tree species form
suitable habitat. Primarily a species of ancient woodlands and wood pastures.
Widespread in Britain.

mycelium and spores, but also partly feeding on other arthropods. Europe, Madeira,
