Overview

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

Rhodonia placenta faces severe decline due to the widespread loss of old-growth coniferous forests, particularly those containing large-diameter fallen logs and stumps essential for its saprophytic lifestyle. Commercial logging practices that remove dead wood and implement short rotation cycles eliminate the specific microhabitat conditions this polypore requires for fruiting body development. Climate change compounds these pressures by altering moisture regimes in forest ecosystems, potentially disrupting the delicate balance of humidity and temperature needed for spore germination and mycelial growth.

Threat summary

Habitat

This wood-decay fungus inhabits mature coniferous forests, particularly those dominated by spruce, fir, and pine species. It colonizes fallen logs, stumps, and dead standing timber in moist forest environments, requiring specific moisture and temperature conditions for optimal growth and reproduction.

Why is Polypore placenta classified as Vulnerable?
Polypore placenta is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. Rhodonia placenta faces severe decline due to the widespread loss of old-growth coniferous forests, particularly those containing large-diameter fallen logs and stumps essential for its saprophytic lifestyle. Commercial logging practices that remove dead wood and implement short rotation cycles eliminate the specific microhabitat conditions this polypore requires for fruiting body development. Climate change compounds these pressures by altering moisture regimes in forest ecosystems, potentially disrupting the delicate balance of humidity and temperature needed for spore germination and mycelial growth.
Where does Polypore placenta live?
Polypore placenta occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
