Specimen notes
Public Note:
Same as 9320 & 9233. Same aniseed smell. This has cap to max 3cm . 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 (possibly very weakly amyloid) 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 (and other collections has amyloid cheilocystidia). No tissue metachromatic. Spores walls are cyanophilous. Reexamination of previous collections does not show amyloid cheilocystidia so not sure where that came from? Not a pleurotus with these non-cylindrical spores, not panellus/resupinatus as both with amyloid different shaped spores. Was kept in Pleurotus as a 'holding pen' but transferred to Panus as new 'holding pen'. I wonder if FUNNZ historical records of a 'blue hygrotrama smelling of aniseed' are this? Also a PDD record currently filed under Hygrophorus (Hygrotrama) which is this. Probably 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. I need to see PDD90281 & 90282. If H.w. then incorrectly placed in Hygrophorus. Should have sarcodimitic tissue in the stem. Does it?
