Cuphophyllus atlanticus is a species of agaric (gilled mushroom) 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.[2] As C. canescens, it has been given the recommended English name of felted waxcap in the United Kingdom.[3] 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 (including C. atlanticus) being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species.[1]

Taxonomy

The species was first described from Norway in 2021 as a result of

DNA sequences. Previously, European specimens had been referred to the similar Cuphophyllus canescens, but the latter species appears to be confined to North America.[2]

Description

inamyloid, subglobose, c. 5.5 to 6 by 4.5 to 5 μm.[2]

Similar species

In Europe, the felted waxcap is distinguished from other grey species of Cuphophyllus by its dry, slightly felted cap that is never viscid or greasy.[4] In North America, C. canescens is very similar, but is said to have drab or brownish tints in the cap and (microscopically) smaller, more globose spores measuring 4 to 5 μm across.[2]

Distribution and habitat

In Europe, DNA studies have confirmed the presence of the felted waxcap in Norway,[2] Sweden,[2] and Scotland.[5] This is the same northerly distribution previously noted for "C. canescens" in Europe.[4] In North America, C. atlanticus has been confirmed from the United States (North Carolina) and Canada.[2]

Recent research suggests waxcaps are neither

saprotrophic but may be associated with mosses.[6]

Conservation

In Europe, Cuphophyllus atlanticus is typical of

sensu lato) is listed as "vulnerable" on the IUCN Red List of Threatened Species.[1]
