Specimen notes
Public Note:
[Cooper] pure tea tree area. FeSO4 dirty salmon, guaiac nil. Cap dark green (then felty) to dark violet (then shiny), depressed, tending to paler and greener in centre. Not striate at cap margin (slightly as skin stretched over base when drying), flesh purple/grey directly under cuticle. Gills D, without lamellulae, Basally interveining, anastomosing at stem, many with distinct grey edge. Stem hollow, with mauve/pink/grey fibrils. Cap and stem surface orange in KOH. Gill and flesh taste slightly bitter but not acrid. Cap peeling halfway. Spore print A . Without thick-walled pleurocystidia - but has to be near tawai. [Leonard] This is R.tawai. There are some thick walled pleurocystidia and the spores and pp are correct. I suspect however that this may be a mixed collection and restricted my examination to two specimens where the coloured lamellar edge was obvious.[Cooper] Sequence suggests this is a new species near tawai. Material with Pat 20/1/2011. Returned Feb. Matches his PL7409. need spores and DCY. Keys to macrocystidiata – why not (spores wrong)? SV-ve, but exuding magenta pigment, some indication of violet granules (in subcutis?) but squash cleared with time. Cap (in felty areas) has a trichoderm of hairs, often forked at base and/or multiple hairs arising from spherical or asymmetric cells but adjacent a layer of spherical cells and forming a layer 100um deep, the next layer is of horizontal filamentous hyphae 250 thick, and then finaly the context of sphaerocysts. Some of the hairs with refractive content in KOH. Hairs multi-septate, thin-walled, rounded at apex, equal along lenth, around 5um diam and to 120um long, hyaline in KOH. Pleuromacrocystidia numerous rounded but mostly capitate, with refractive content, sometimes yellowish in KOH, not thick-walled. Cheilomacrocystidia with brown content and thinner than pleuro, and in fascicles on gill edge.Cuticle of stipe a filamentous layer over sphaerocysts, terminal layer with occasional cystidia/hairs like cap. Spores from print (which, it seems, might be something else!), length=6.3–8.0µm (µ=6.7, σ=0.39), width=4.2–4.9µm (µ=4.6, σ=0.21), Q=1.3–1.6µm (µ=1.46, σ=0.07), n=20, ellipsoid, ornamentation to 0.6um, apiculus oblique 1.2 long by 1.2um base. Sometimes with a plage, without amyloid spot. Ornamentation of low ridges forming an almost complete reticulum. Spores on gill different, with plage and violet amyoid spot, spore length=7.1–8.3µm (µ=7.8, σ=0.35), width=6.0–6.9µm (µ=6.3, σ=0.28), Q=1.1–1.4µm (µ=1.23, σ=0.08), n=20, ornamentation to 0.6um . Think I have to ignore the spore print. Not macrocystidiata as that with thick-walled pleurocystidia. Not pilocystidiata as that with Nothofagus and much denser, longer pilocystidia.
