Psathyrella jacobssonii

Local name: skuggspröding

Unknown

Overview

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

Psathyrella jacobssonii faces significant pressure from habitat degradation in its specialized woodland environments, particularly through intensive forestry practices that alter soil chemistry and microhabitat conditions essential for fruiting body development. Climate change poses an additional threat by disrupting the delicate moisture and temperature regimes required for this fungus to complete its reproductive cycle. Urban expansion and agricultural conversion of forest margins further fragment the species' already limited suitable habitat.

Threat summary

Habitat

This species inhabits deciduous and mixed woodlands, typically growing on decaying organic matter in nutrient-rich soils with specific pH requirements. It shows a preference for undisturbed forest floors with stable moisture levels and established mycorrhizal networks.

Why is skuggspröding classified as Vulnerable?
skuggspröding 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. Psathyrella jacobssonii faces significant pressure from habitat degradation in its specialized woodland environments, particularly through intensive forestry practices that alter soil chemistry and microhabitat conditions essential for fruiting body development. Climate change poses an additional threat by disrupting the delicate moisture and temperature regimes required for this fungus to complete its reproductive cycle. Urban expansion and agricultural conversion of forest margins further fragment the species' already limited suitable habitat.
Where does skuggspröding live?
skuggspröding occurs in Belgium, Finland, Norway, Sweden, Switzerland, and United States. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to skuggspröding?
The main threats to skuggspröding are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
