Hygrocybe aurantiosplendens

About

Hygrocybe aurantiosplendens is an agaric in the family Hygrophoraceae. In the United Kingdom, it has been given the recommended English name of orange waxcap. The species has a European distribution and typically occurs in grassland where it produces basidiocarps in the autumn. Threats to its habitat have resulted in the species being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species. It has also been reported on both the East and West coasts of North America, but it is uncertain if the American ecotypes are in fact conspecific and they may represent distinct species.
