Cuphophyllus atlanticus

About

Cuphophyllus atlanticus is a species of agaric in the family Hygrophoraceae. Until recently (2021), the species was considered to be conspecific with the North American Cuphophyllus canescens, but DNA sequencing has shown that it is distinct. As C. canescens, it has been given the recommended English name of felted waxcap in the United Kingdom. Cuphophyllus atlanticus has a European and North American distribution, occurring in Europe mainly in agriculturally unimproved grassland. Threats to its habitat have resulted in C. canescens being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species.
