Article: Horak, E. (1973). Fungi Agaricini Novazelandiae I-V. Beihefte zur Nova Hedwigia 43: 200 p.
Description: Pileus 15-50 mm diam., conical to sharply umbonate, edge inturned (even in aged carpophores), light blue turning greenish blue and finally ochraceous coloured near the apex, hygrophanous, striate towards the margin, dry, appressed fibrillose. Lamellae adnexed or subfree, bluish when young, becoming bluish-reddish brown to pink brown, moderately crowded, gill edge concolorous, even or irregularly scalloped. Stipe 50-100(-150) x 3-5 mm, cylindrical, equal or attenuated upwards, concolorous with pileus, fading to brownish, whitish at the base, dry, fistulose, fragile, fibrillose, frequently twisted. Context bluish or bluish-greenish (especially at the base). Odor and taste indistinct. Chem. reactions: on pileus: KOH - light reddish-brown; HCl yellowish; NH₃- negative.
Spore print purplish or deep red-brown. Spores 11-15 x 11-14 µm, cuboid. basidia 40-60 x 15-20 µm, 4-spored. Cheilocystidia 40-60 x 8-14 µm, fusoid, with long tapering and apically rounded neck, membrane thin-walled. pleurocystidia none. Cuticle a cutis composed of repent or slightly suberect, cylindrical hyphae (5-13 µm diam.), terminal cells rounded, membrane thinwalled, with indistinct plasmatic pigment. Clamp connections present.
Habitat: Among litter and moss on soil particularly in broad-leaved forests and Podocarpus-forests, rarely occurring in Nothofagus-bush. New Zealand.
Notes: This fungus is common in the lowland-forests of New Zealand, especially on the western side of the three islands. The pale blue or greenish colours of this beautiful Entoloma attracted the interest of all collectors (Haast, Hochstetter, Colenso, Berggren) since the very beginning of botanical investigations in this country (see Stevenson 1962: I.c.). So it is not surprising that the species was subsequently described several times (see list of synonyms).
According to our present knowledge, the closest relatives of E. hochstetteri occur in Japan (Imazeki & Hongo 1962) and North America (Hesler 1967).

Notes: There is no type material in the Kew Herbarium but the taxon is well documented with a painting executed by J. V. Haas (cf. Stevenson, 1962: 234; Horak, 1971: 417).

Description: Entirely clear sky-blue. Pileus acutely conical, splitting, slightly striate, 4 cm. high; gills free, very broad (1 cm.) in front, gradually narrowing to the stem ; stem 12 cm. high, 7-8 mm. thick, hollow, base thickened.
Habitat: Middle Island: Beech forests, amongst moss, Nelson Province. Julius Haast.
Notes: The present species is somewhat uncertain, being described by Berkeley from a crude drawing only. To this species Cooke refers a drawing of a Fungus from Waitaki, with the following remark : "The colour as shown in the drawing is verdigris-green, but in other respects it does not appear to differ from the typical form in any essential particular."

Notes: The colour as shown in the drawing is verdigris-green, but in other respects it does not appear to differ from the typical form in any essential particular.

Notes: Hygrophorus cyaneus Berkeley (3 D, 4, 16, 27) = Entoloma hochstetteri (Reichardt) Stevenson
No specimens have been preserved but a well executed painting of this distinctive fungus by J. V. Haast exists at Kew. For further details see Stevenson (27).

Notes: The poor state of the exsiccaturn (N.Z., Dr Berggren) did not allow detailed observations, but there is no doubt that this species belongs to Hygrophorus, as already stated by Stevenson (28).
