Xenasma rimicola
Local name: eggsporestålskinn
Xenasma rimicola, commonly known as eggsporestålskinn, is a corticioid fungus that forms thin, crust-like fruiting bodies on decaying wood substrates. This species produces distinctive egg-shaped spores and plays a crucial ecological role as a wood decomposer, breaking down cellulose and lignin in forest ecosystems.

Species Profile
Xenasma rimicola, commonly known as eggsporestålskinn, is a corticioid fungus that forms thin, crust-like fruiting bodies on decaying wood substrates. This species produces distinctive egg-shaped spores and plays a crucial ecological role as a wood decomposer, breaking down cellulose and lignin in forest ecosystems.
Xenasma rimicola faces significant threats from habitat loss due to deforestation and forest degradation, which reduces the availability of suitable dead wood substrates essential for this fungal species. Climate change poses additional risks by altering forest moisture regimes and temperature patterns that affect the species' reproductive success and substrate colonization.
Key Facts
Habitat & Distribution
This corticioid fungus inhabits dead wood and bark crevices in temperate and boreal forests, particularly on decaying hardwood trees and fallen logs in moist woodland environments. It typically occurs in mature forest ecosystems with abundant coarse woody debris.
Threats
