Mycosphaerella chimaphilae

Unknown

Overview

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

Mycosphaerella chimaphilae faces severe threats from habitat destruction as old-growth forests containing its host plants are cleared for development and logging. Climate change poses additional risks by altering the moisture and temperature conditions essential for this fungal pathogen's survival on Chimaphila species. The species' highly specialized relationship with specific host plants makes it particularly vulnerable to any factors affecting Chimaphila populations.

Threat summary

Habitat

This fungal species inhabits temperate and boreal forests where it occurs as a pathogen on Chimaphila (pipsissewa) plants. It requires the specific microclimate conditions found in mature forest understories with adequate moisture and stable temperatures.
