Clavaire noircissante

Phaeoclavulina macrospora

Clavaire noircissante is a distinctive coral fungus characterized by its branched, club-like fruiting bodies that darken to black when bruised or aged, giving it its common name. This saprobic fungus plays a crucial ecological role in forest ecosystems by decomposing organic matter and recycling nutrients back into the soil.

02Description

Species Profile

Clavaire noircissante is a distinctive coral fungus characterized by its branched, club-like fruiting bodies that darken to black when bruised or aged, giving it its common name. This saprobic fungus plays a crucial ecological role in forest ecosystems by decomposing organic matter and recycling nutrients back into the soil. Its relatively large spores distinguish it from closely related species in the Clavariaceae family.

Phaeoclavulina macrospora faces severe decline primarily due to habitat loss from deforestation and forest fragmentation in its limited range. The species is particularly vulnerable due to its specialized ecological requirements and small population size, making it highly susceptible to environmental changes and human disturbance.
