Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Orchard Toothcrust faces severe threats from habitat loss due to the decline of traditional orchards and old-growth forests containing its essential host trees. Climate change and intensive agricultural practices have dramatically reduced suitable substrates, while pollution and pesticide use in modern farming further compromise the fungal communities this species depends on for survival.

Threat summary

Habitat

This fungus grows on dead and dying hardwood trees, particularly fruit trees in traditional orchards, old apple and pear trees, and occasionally on other deciduous species in mature woodland edges and parkland environments. It requires specific moisture conditions and substrate chemistry found in aging wood of broadleaf trees, especially in semi-natural and traditional agricultural landscapes.
