Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Sharp-scaly Pholiota faces significant pressure from widespread deforestation and habitat fragmentation across its range, particularly affecting the mature deciduous forests it requires for fruiting. Climate change poses an additional threat by altering moisture regimes and temperature patterns essential for this saprophytic fungus's reproductive cycles. The species' dependence on specific deadwood substrates makes it vulnerable to forest management practices that remove fallen logs and standing dead trees.

Threat summary

Habitat

Sharp-scaly Pholiota inhabits mature deciduous and mixed forests, growing saprophytically on decaying hardwood logs, stumps, and fallen branches. The species shows a preference for well-established forest ecosystems with abundant deadwood and stable moisture conditions.
