Rautensporiger Rasling

Lyophyllum deliberatum

Unknown

Overview

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

Lyophyllum deliberatum faces severe population decline due to habitat destruction from urban development and agricultural expansion in its limited European range. The species' specialized ecological requirements and slow reproductive rate make it particularly vulnerable to environmental changes. Climate change poses an additional threat by altering the specific temperature and moisture conditions this fungus requires for fruiting and spore dispersal.

Threat summary

Habitat

This rare mushroom species inhabits deciduous and mixed forests, particularly favoring beech and oak woodlands with rich, well-drained soils. It typically grows in small clusters on forest floors during autumn months, requiring specific soil chemistry and mycorrhizal associations to thrive.
