Peniophorella echinocystis

Unknown

Overview

Peniophorella echinocystis is a rare corticioid fungus characterized by its thin, cream-colored to pale ochre fruiting bodies that form resupinate crusts on decaying hardwood substrates. The species is distinguished by its distinctive spiny cystidia and small, ellipsoid spores, making it easily recognizable under microscopic examination. As a saprobic decomposer, it plays a crucial role in breaking down dead wood and recycling nutrients in forest ecosystems.

Peniophorella echinocystis, a critically endangered corticioid fungus, faces severe population decline primarily due to habitat loss from deforestation and forest fragmentation in its limited range. The species' highly specific substrate requirements and narrow ecological niche make it extremely vulnerable to environmental changes and human disturbance.

Threat summary

Habitat

This species inhabits the undersides of fallen logs and branches of mature deciduous trees, particularly oak and beech, in old-growth and semi-natural forest environments. It requires consistently moist conditions and is typically found in shaded forest floors where humidity levels remain stable throughout the year.

Frequently asked questions

Why is flodtagging classified as Critically Endangered?
flodtagging is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Peniophorella echinocystis, a critically endangered corticioid fungus, faces severe population decline primarily due to habitat loss from deforestation and forest fragmentation in its limited range. The species' highly specific substrate requirements and narrow ecological niche make it extremely vulnerable to environmental changes and human disturbance.
Where does flodtagging live?
flodtagging occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to flodtagging?
The main threats to flodtagging are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
