Overview

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

Multiclavula coronilla faces severe threats from habitat destruction and degradation of its specialized moss and bryophyte substrates in temperate and boreal forest ecosystems. Climate change poses additional risks by altering moisture regimes and temperature conditions essential for both the fungus and its bryophyte hosts. The species' highly specific ecological requirements and limited distribution make it extremely vulnerable to environmental changes.

Threat summary

Habitat

Multiclavula coronilla occurs in moist temperate and boreal forests where it grows as a parasite or associate on mosses and other bryophytes. The species requires specific microhabitat conditions with consistent moisture levels and is typically found in undisturbed forest environments with well-developed bryophyte communities.

Frequently asked questions

Why is club lichen classified as Critically Endangered?
club lichen is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Multiclavula coronilla faces severe threats from habitat destruction and degradation of its specialized moss and bryophyte substrates in temperate and boreal forest ecosystems. Climate change poses additional risks by altering moisture regimes and temperature conditions essential for both the fungus and its bryophyte hosts. The species' highly specific ecological requirements and limited distribution make it extremely vulnerable to environmental changes.
