Species Profile
Crepidotus cinnabarinus is a species of saprophytic fungus in the family Crepidotaceae with a stipeless sessile cap distributed in North America and Europe. It is highly conspicuous and often found on fallen branches and rotting trunks of broad leafed trees. In England it appears from late summer to autumn.
The Cinnabar Oysterling faces severe decline primarily due to habitat loss from deforestation and land conversion in its limited range. As a specialized fungus dependent on specific host trees and forest conditions, it is extremely vulnerable to environmental changes and has very restricted distribution making populations fragile.
