Assessment Notes

Taxonomic notes

Crustodontia chrysocreas is characterized by a smooth or slightly warted yellowish-brown hymenium when fresh and is usually accompanied by bright yellow mycelium in worm holes, rays, or open areas in the wood substrate. These areas stain purple in 2% KOH. Crustodontia chrysocreas is simillar to P. ailaoshanensis, but differs due the smooth to slightly warted hymenial surface with ochraceous-buff to yellow ochre color and smaller, narrowly ovoid basidiospores (Lombard et al. 1975).

Why suggested for a Global Red List Assessment?

Geographic range

The species in known in 17 countries and about half of the records are in South Korea.

Population and Trends

There are about 531 records of this species in GBIF, being 153 of them in South Korea.

Population Trend: Uncertain

Habitat and Ecology

In Brazil, the species is found in the Amazonia and Atlantic Forest.

Subtropical/Tropical Moist Lowland Forest


In Brazil, this species is not well distributed, registered only in pluvial forest domain. The Amazon has currently the highest rates of deforestation in the last decades and the Atlantic Forest is a hotspot.

Research needed

The Brazilian’s specimens seems to be phylogenetically different from C.chrysocreas s.s. (unpublished data). Thus, other areas should be studied and more sequences are nedeed in order to assess the distribution and delimitation of this species.
