Xerula pudens
Local name: Collybie à poils ras, Collybie à long pied
Xerula pudens is a distinctive mushroom species characterized by its smooth cap surface and notably elongated stem, earning it the common name 'long-stemmed collybia.' This saprotrophic fungus plays a crucial ecological role in forest ecosystems by decomposing organic matter and recycling nutrients back into the soil.

Species Profile
Xerula pudens is a distinctive mushroom species characterized by its smooth cap surface and notably elongated stem, earning it the common name 'long-stemmed collybia.' This saprotrophic fungus plays a crucial ecological role in forest ecosystems by decomposing organic matter and recycling nutrients back into the soil. The species typically produces pale-colored fruiting bodies with caps that can reach several centimeters in diameter.
Xerula pudens faces significant threats from habitat loss and degradation due to deforestation and forest fragmentation across its range. As a specialized saprobic fungus dependent on specific deadwood substrates in mature forest ecosystems, it is particularly vulnerable to logging activities and forest management practices that remove decaying wood. Climate change may also be altering the moisture and temperature conditions necessary for its fruiting and spore dispersal.
Key Facts
Habitat & Distribution
This species occurs in mature deciduous and mixed forests, particularly beech and oak woodlands, where it grows as a saprobe on buried or partially buried deadwood and root systems. It typically fruits in moist, shaded forest floors with rich organic matter and stable microclimate conditions.
Threats
Deforestation and logging
Forest fragmentation
Climate change impacts on forest moisture regimes
Intensive forest management practices
Removal of deadwood and forest debris
