Porpolomopsis calyptriformis is a species of agaric (gilled mushroom) in the family Hygrophoraceae. It has been given the recommended English name of Pink Waxcap in the UK. The species has a north temperate distribution, occurring in grassland in Europe and in woodland in North America and northern Asia. It typically produces basidiocarps (fruit bodies) in the autumn. In many European countries, P. calyptriformis is of conservation concern, appearing on national red lists of threatened fungi.
The species was first described in 1838 by the Rev. Miles Joseph Berkeley as Agaricus calyptraeformis (so spelt), based on specimens he collected locally in England. In 1889, Swiss mycologist Victor Fayod moved it to the genus Hygrocybe. The specific epithet comes from Greek καλὐπτρα (= a woman's veil) + Latin forma (= shape), hence "veil-shaped".
In 2008, Bresinsky proposed the genus Porpolomopsis to accommodate the species. Recent molecular research, based on cladistic analysis of DNA sequences, found that Porpolomopsis calyptriformis does not belong in Hygrocybe sensu stricto and confirmed its removal to the genus Porpolomopsis.
