Gilbender Rasling

Lyophyllum aemiliae

The Gilbender Rasling (Lyophyllum aemiliae) is a rare saprotrophic fungus characterized by its distinctive pale gray to silvery caps that develop characteristic bending or curving stems as they mature. This critically endangered species plays a vital ecological role in decomposing organic matter in its specialized habitat, contributing to nutrient cycling in fragile ecosystems.

02Description

Species Profile

The Gilbender Rasling (Lyophyllum aemiliae) is a rare saprotrophic fungus characterized by its distinctive pale gray to silvery caps that develop characteristic bending or curving stems as they mature. This critically endangered species plays a vital ecological role in decomposing organic matter in its specialized habitat, contributing to nutrient cycling in fragile ecosystems.

The Gilbender Rasling faces severe threats from habitat destruction due to deforestation and urban development in its limited range. Climate change is altering the specific moisture and temperature conditions this fungus requires for fruiting and mycelial growth. Pollution from agricultural runoff and industrial activities is degrading the soil chemistry essential for this species' survival.
