The annulus in this material is not apparent. Spores length=8.6-11.0µm (µ=9.7, σ=0.63), width=7.5-9.8µm (µ=8.6, σ=0.74), Q=1.0-1.3µm (µ=1.14, σ=0.07), n=17. These spores are larger than quoted by Pegler for A. manicata, and I suspect I measured some immature spores so correct measurments are likley to be larger. Wood also measured 7.8-10.5 x 7.5-9.3 for Australian material and 9.3 x 8.1 for Hawaii (RET). Basidia with basal clamps. Most hyphae with occasional/common clamps. This material, like other NZ collections of nauseosa/manicata is NOT sticky/water absorbent, like say A. sp. 2 (galerumgandalfi). The material feels quite different. The sequence data for this and other NZ specimen is the same as that from Australia and Hawaii. The spores sizes for A. nauseosa also seem variable. I remain unconvinced these are different taxa, and A.. manicata provides the earliest name anyway.
