Collections Examined

Herb. HK. ZT 68/464: 'Mangarakau, Whanganui-Inlet, Prov. Nelson, N.Z.; leg. Horak, 16.V.1968'. - Herb. HK. ZT 68/526: 'Pukeiti, Pouakai Range, Mt. Egmont, N.Z.; leg. Horak,11.IV.1968'.

Description

Pileus 5-20 mm diam., hemispherical, convex or becoming flat with depressed centre, scarlet or tomato red, glutinous, conspicuously striated, glabrous. Lamellae adnexed to adnate, whitish-reddish when young becoming reddish-orange, ventricose, gill edge concolorous. Stipe 10-35 x 1-2 mm, cylindric, equal, concolorous with pileus or reddish-orange, glutinous, glabrous, fistulose, single. Context red-orange, yellowish towards the base of the stipe. Taste and odor not distinctive. Chemical reactions on pileus: KOH - yellow. Spores 8-10.5 x 5-7 µm, ovoid, smooth, inamyloid. Basidia 32-35 x 7-10 µm, 4-spored. Cystidia absent. Cuticle an ixocutis composed of repent or suberect cylindric, strongly gelatinized hyphae (4-10 µm diam.), plasmatic and encrusting pigment present. Clamp connections on the septae.

Habitat

On soil or on rotten bark under Dacrydium cupressinum. New Zealand; South America (Chile).

Notes

Since we have not studied the type of G. subheteromorpha Singer we refer our N.Z. material with some hesitation to this taxon. But there is a striking coincidence of the macroscopic and microscopic characters as well so it may likely be that the area of distribution stretches from Chile to New Zealand. Furthermore the N.Z. fungus is also closely related to H. araucana Singer, another species described from Chilean forests.
