Gliophorus europerplexus
Gliophorus europerplexus is a species of agaric in the family Hygrophoraceae. It has been given the recommended English name of butterscotch waxcap. The species has a European distribution, occurring mainly in agriculturally unimproved grassland. Threats to its habitat have resulted in the species being assessed as globally "vulnerable" on the IUCN Red List of Threatened Species.
Taxonomy
The species was first described from Wales in 2013, as a result of molecular research, based on cladistic analysis of DNA sequences. It was formerly considered to be conspecific with the North American species Gliophorus perplexus, which it otherwise resembles.Description
Basidiocarps are agaricoid, up to 60 mm tall, the cap hemispherical to broadly umbonate becoming flat, up to 25 mm across. The cap surface is smooth, highly viscid when damp, pink-brown to orange-brown. The lamellae are waxy, cap-coloured or paler. The stipe is smooth, viscid, cap-coloured or paler, lacking a ring. The spore print is white, the spores smooth, inamyloid, ellipsoid, measuring about 7 to 9 by 4.5 to 5.5 μm.Similar species
The parrot waxcap Gliophorus psittacinus is similar, but is typically green and, if not, retains this colour at the top of the stipe. The jubilee waxcap Gliophorus reginae is also similar, but has a dull violet-purple cap and white stipe.Distribution and habitat
The butterscotch waxcap is currently known from Wales, England, the Isle of Man and Spain, but is likely to be more widespread in western Europe. Like most other European waxcaps, it occurs in old, agriculturally unimproved, short-sward grassland.Recent research suggests waxcaps are neither mycorrhizal nor saprotrophic but may be associated with mosses.
