Stilbohypoxylon macrosporum

Declining

Overview

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

Stilbohypoxylon macrosporum faces severe threats from deforestation and habitat fragmentation across its limited range in tropical forests. The species' dependence on specific host trees and microhabitat conditions makes it particularly vulnerable to logging activities and forest conversion for agriculture. Climate change poses an additional threat by altering the moisture and temperature regimes essential for this fungal species' survival and reproduction.

Threat summary

Habitat

This fungal species inhabits tropical and subtropical moist forests, typically growing on decaying wood and bark of specific host trees. It requires stable humidity levels and consistent forest canopy cover to maintain the microenvironmental conditions necessary for its development.
