Species Profile
Pleurotus calyptratus, is a species of fungus from the family Pleurotaceae. It has a distinctive delicate veil on young fruiting bodies. Phylogenetic research has shown that while it belongs to P. djamor-cornucopiae clade, it forms its own intersterility group.
Pleurotus calyptratus faces significant threats from habitat loss due to deforestation and degradation of its host tree substrates. Climate change and altered precipitation patterns further threaten the specific moisture conditions required for this fungal species to fruit and reproduce successfully.
Key Facts
Habitat & Distribution
This saprophytic fungus grows on decaying hardwood trees and fallen logs in temperate and subtropical forests, particularly favoring oak, beech, and other deciduous species. It requires specific humidity and temperature conditions found in mature forest ecosystems with adequate canopy cover.
