Overview

Bläulicher Zwerg-Zärtling (Entoloma cyanulum) is a small, distinctive mushroom characterized by its bluish cap coloration and delicate stature. This saprophytic fungus plays an important ecological role in nutrient cycling by decomposing organic matter in forest ecosystems. Its small size and subtle blue hues make it easily overlooked among forest floor debris.

Bläulicher Zwerg-Zärtling (Entoloma cyanulum) is declining primarily due to habitat loss and degradation of its specialized grassland ecosystems. Agricultural intensification, urban development, and changes in traditional land management practices have significantly reduced the availability of suitable habitat for this rare fungal species.

Threat summary

Habitat

Entoloma cyanulum typically occurs in deciduous and mixed forests, particularly favoring areas with rich leaf litter and well-developed humus layers. The species shows preference for shaded, humid microsites often associated with decaying wood and organic debris on the forest floor.
