Entoloma nausiosme

Local name: Kvalmende rødblad

Kvalmende rødblad (Entoloma nausiosme) is a distinctive mushroom species characterized by its reddish-brown cap and nauseating odor, which gives it both its common and scientific names. This saprobic fungus plays a crucial ecological role in decomposing organic matter in forest ecosystems, contributing to nutrient cycling and soil health.

02Description

Species Profile

Kvalmende rødblad (Entoloma nausiosme) is a distinctive mushroom species characterized by its reddish-brown cap and nauseating odor, which gives it both its common and scientific names. This saprobic fungus plays a crucial ecological role in decomposing organic matter in forest ecosystems, contributing to nutrient cycling and soil health.

Entoloma nausiosme faces severe population declines primarily due to habitat loss from agricultural intensification and urban development in its limited range. The species' specialized ecological requirements and small population size make it particularly vulnerable to environmental changes and habitat fragmentation.
