Psilocybe aucklandiae is a species of agaric fungus in the family Hymenogastraceae known from the Auckland Region of New Zealand, where it grows from clay soils in exotic pine plantations and native forests. It is phylogenetically similar to or almost the same as Psilocybe zapotecorum from Mexico and South America. As a blueing member of the genus Psilocybe it contains the psychoactive compounds psilocin and psilocybin.

The cap is 15–55 mm diam., broadly conic, expanding to broadly umbonate to more or less flattened, with edges becoming slightly upturned and often splitting; dry; lacking veil remnants; dark brown to yellow-brown, striate (radially lined) to edge, hygrophanous, drying to pale yellow-brown to straw-coloured; staining greenish-blue with damage or age; flesh white. The gills are adnate (broadly attached to the stem), close, greyish yellow-brown, maturing dark violaceous, with a conspicuous pale narrow margin. The stipe is 35-100 x 1.5–5 mm, cylindric, finely pruinose in the upper part and silky-fibrillose near the base, white, yellow or pinkish purple brown, with brownish flesh. Veil cortinoid and poorly developed, disappearing as caps mature. All parts staining deep greenish-blue or blackish-blue with damage. Spore print violet brown.

Spores measure (6.5-)7-9.5 x 4-5.5 x 3.5-4.5 μm, 8.1 x 4.9 x 4.3 μm average, ovate in face view, elliptic-ovate in side view; brown-walled and smooth, 0.5 μm thick with apical pore; Basidia 20-28 x 4.5-6 μm, cylindric, with 4 spores, clamped; Cheilocystidia 15-32 x 4-8 μm, ventricose-rostrate (swollen and uneven with a beak), with long, tapering, flexuous and sometimes bifurcate neck (forked in two), transparent, thin-walled, up to 12 μm long; Pleurocystidia 13-19 x 4.5-6 μm, scattered, similar to cheilocystidia but with shorter neck, up to 4.5 μm.

Psilocybe zapotecorum in Mexico and South America, as noted by Guzman et al. (1991), “P. aucklandii is very similar to P. zapotecorum R. Heim emend. Guzman, which is common in Mexico and known from South America. The two species are barely distinguishable microscopically, although comparison with published descriptions (Guzman 1983) show that P. aucklandii may have slightly narrower pleurocystidia and slightly wider spores. Published illustrations of P. zapotecorum (Guzman 1983) appear to show that P. aucklandii is a less robust species.
