Specimen notes
Public Note:
Cap 3cm hemispherical. Stem 4mm x 5cm, bluing. Without pleurocystidia (and both makaroae and aucklandii are supposed to have them, although 'inconspicuous' in aucklandiae). Some spores slightly asymmetrical in side-view. Spore wall thickness 0.5–0.7µm (µ=0.56, σ=0.08), n=19 which I would consider to be 'thick-walled'. P. aucklandiae is put in Guzman's section Zapotecorum which is supposed to have thin-walls but P.a. is described with a wall thickness of 0.5um! The switch is between Zapotecorum (thin walled), Aztecorum (thick-walled, drying white, with asymmetrical spores), Semilanceata (thick-walled, symmetric, not drying white). Spore length here =8.6–11.3µm (µ=9.5, σ=0.8), width=5.2–6.5µm (µ=5.8, σ=0.4), Q=1.4–1.8µm (µ=1.6, σ=0.1), n=18. Doesn't actually fit anything in Guzman's sections semilanceata or zapotecorum. The spores here are not angled. The later described P. makarorae is placed in section mexicanae which indicates it would have rhomboid spores. Neck on cystidia up to 12um long, width of cystidia 6.4 SD0.7,n=13. The tips are thick-walled and frequently with an exudate (in Melzers). So this is closer to aucklandii than makarorae. I wouldn't call Akaroa tropical or sub-tropical, combined with apical exudate on cystidia, and this on litter, not wood, may mean this is something else again. Sequences say P. cyanescens ss in the azurescens/cyanescens/subaeruginosa complex. This has macro-morphology of P. allenii (thin stem, no wavy cap) but is not.
