When: 2009-06-30
Herbarium specimen reported

Notes: Pileus: 15-40mm; Hemispherical later becoming plano-convex to subumbilicate; White sometimes with light tan tint; faint translucent striate margin; viscid; hygrophanous.
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.
Cystidia: Absent.
Habit-habitat: Solitary to gregarious on soil in broadleaf conifer forest; Podocarpus totara, Dacrycarpus dacrydioides, Leptospermum scoparium, Cyathea dealbata and Dicksonia squarrosa.

Similar to Hygrophorus involutus although the spores in this collection are larger, the basidiomes are hygrophanous and the young specimens do not have a strongly inrolled margin, also the lamellae in H. involutus are crowded.

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.
