Specimen notes
Public Note:
rooting. pileus surface elastic, wrinkled. with hairs, spores globose 12um. 4-spored cap 3cm diameter.. Brown resinous material exuding into melzers. Spores length=12.6–14.4µm (µ=13.3, σ=0.46), width=11.7–13.4µm (µ=12.3, σ=0.49), Q=1.0–1.2µm (µ=1.08, σ=0.05), n=20. Pleurocystidia utriform. and spore re-measurement length=12.2–14.6µm (µ=13.3, σ=0.60), width=11.2–13.2µm (µ=12.2, σ=0.56), Q=1.0–1.2µm (µ=1.09, σ=0.05), n=20. Requires sequence. See Nova Hed 87, p1, 2008 rather than Beihefte.
Trichofera - spores 10-15.5 x 9.5-14, Q=1.16, 4-spored, pleurocystidia utriform, often clamped
gigaspora - spores 11-20 x 10-14, Q=1.24, 4-spored, pleurocystidia fusiform, clamped
mundroola - spores 15-21.5 x 10-15, Q=1.56, 2-spored, pleurocystidia fusiform, no clamps
raphanipes - spores 14-20 x 10-18, Q=1.24. 2-spored, pleurocystidia fusiform, no clamps
colensoi - spores 12-16 x 12.5-13.5, Q=1.07, 4-spored, pleurocystidia utriform, clamped
superbiens - spores 12-19 x 9-13, Q=1.32, 4-spored, pleurocystidia fusiform, (unclamped?)
gigaspora/trichofera/superbiens/mundroola in same clade. Of these mundroola/raphanipes separated by being 2-spored. H. raphanipes phylogenetically different and perhaps not likely in NZ. gigaspora/trichofera/superbiens seem doubtfully distinct (Q variable, maybe pleuro stable) and H. superbiens is the earliest name. If not then this is H. trichofera.
If 4-spored and olive cap and greyish gills then colensoi (few authors have seen fresh material, hence cap described as dark brown)
if 4 spored and brown cap and white gills then superbiens
if 2-spored & stipe grey-brown then mundroola (and may be just 2-spored form of H. superbiens)
if 2-spored ans stipe white then maybe atrocaerulea.
