Description: Pileus 12-20 mm diam., umbilicate, with
distinct conical papilla at the depressed centre, striate margin incurved, green,
fading in aged specimens, covered with small appressed squamules, dry, hygrophanous.
Lamellae (L 10-13, 1 3), emarginate or slightly decurrent, greenish when young
becoming yellow-green with pinkish-brown tinge, gill edge fimbriate and dark
blue. Stipe 30-40 x 1-1.5 mm, cylindrical, slender, yellowish, glabrous, dry,
fistulose. Context greenish-olive. Odor and taste not distinctive.
Spores
9.5-11 x 6-8 µm, 5-6-sided. Basidia 23-28 x 9-10 µm, 4-spored. Cheilocystidia
cylindrical-articulate, terminal cell (25-50 x 8-12 µm) apically rounded, with
thin-walled membrane, conspicuous greenish-blue plasmatic pigment present. Clamp
connections abundant.
Habitat: On
soil in forests (under Nothofagus spp., and Leptospermum spp.).
New Zealand.
Notes: The
distinctive characters of this species include the green colour of the papillate-umbilicate
pileus, blue gill edge and cylindrical, articulate cheilocystidia. Weathered
carpophores are suggestive of E. chloroxanthum Stev. which lacks the
papilla and cheilocystidia.
