Hygrocybe chlorophana is of conservation concern, appearing on national red lists of threatened fungi.

From first-nature.com:
A common waxcap of cropped pasture and parkland, like nearly all waxcaps Hygrocybe chlorophana is an autumn and early winter species. These lovely golden fungi are generally found in small trooping groups; they are sometimes seen in churchyards, but sheep-grazed upland commons are usually much better places to try. Although generally considered edible, Golden Waxcaps are easily confused with other inedible yellow waxcap species
