Specimen notes
Public Note:
Same as 9320 & 9233. Same aniseed smell. This has cap to max 3cm, stem 3mm diam x 25mm long . Gills are leaden grey/sky blue, broad, almost cantharelloid. Flesh white, blue in stem. Cap with dark violet and tinges of blood red. Texture rubbery. Taste almondy. Cap not gelatinised, a trichoderm, with dark occasional hymeniderm-like brown pilocystidia, with diamond-shaped crystals, pigment intracellular and extra-cellular zebra encrustation, unclamped, no tissue amyloid or dextrinoid. Oil drops in melzers. Spores subglobose with bubble and prominent apiculus 4.4-5.0(4.9) SD0.2, n=10 (including apiculus) x 3.2-3.8(3.4) SD0.2, n=10. Without cheilo or pleurocystidia. No tissue metachromatic. Spores walls are cyanophilous. Reexamination of previous collections does not show amyloid cheilocystidia, and I assume they were the pileus hydropid veiscles translocated in poor material. FUNNZ historical records of a 'blue hygrotrama smelling of aniseed' are this. Also a PDD record currently filed under Hygrophorus (Hygrotrama) which is this. This is same as Stevensen's Hygrophorus waikanaensis which has a poor type that Egon couldn't decipher. The occasional pilocystidia would have led him to mention Hydropus. [JAC:30/04/2025] re-examination of the lamella edge does not show cheilocystidia, just basidioles and the remarkebly long thin & collapsing basidia. Sarcodimitic hyphal elements are present.
