Lamellae: Deeply decurrent; distant; intervenose in mature specimens; white; edges concolorous.
Stipe: 30-50mm x 5-8mm; Cylindrical to slightly flattened; tapering towards base; dry; white with pale salmon-pink tint at base.
Spores: 8.5-9.5um x 5.5-6.5um; Ellipsoid; white in deposit.
Basidia: 4 spored; 50-53um x 6-7um.

That is interesting, I used Egon Horak’s monograph but could not find a match, I think this is probably another new record from New Zealand!

I have found Hygrophorus involutus in Leura Forest in NSW

and this mushie here has nothing to do with it .. it belongs to subgenus Cuphophyllus of Hygrocybe … I’m sure the species can be found in Young.

Looks to me like something close to Hygrocybe virginea.
