UNKNOWN HOST. Auckland, Mamaku Forest, W. N. Cheesman, 1914 (type collection, in herb. Kew).

Hymenophore perennial, membranous-ceraceous, adherent, effused forming irregular areas to 8 x 5 cm; hymenial surface at first pallid orange, drying ochre, even, not creviced; margin thinning out, isabelline, or abrupt and cliff like when dark brown. Context isabelline, 300-750 µm thick, of several obscure zones, basal layer of compact intertwined hyphae, intermediate layer of compact erect hyphae embedding metuloids and at the base masses of crystals; generative hyphae 5-6 µm diameter, walls 0.2 µm thick, hyaline, many encrusted in part with granules of mucilage, crystals, or both, staining blue, without clamp connections. Metuloids arranged in 3-7 irregular rows in the context, some projecting to 35 µm, fusiform or aculeate, 40-55 x 5-8 µm, encrusted on the upper third with orange or yellow masses of mucilage granules or calcium crystals. Hymenial layer to50 µm deep, a dense palisade of basidia, paraphyses, and metuloids. Basidia subclavate, 14-25 x 5.5-6 µm, bearing 4 spores; sterigmata erect, slender; to 5 µm long. Paraphyses cylindrical, 18-24 x 3.5-4 µm.Spores elliptical, 4.5-5 x 2.5-3 µm, walls smooth, hyaline, 0.1 µm thick.

DISTRIBUTION: New Zealand.

HABITAT: Effused on bark of dead branches.

Only the type collection has yet been found. Metuloids are encrusted on their upper third with either granules of yellow or orange mucilage, or calcium crystals, sometimes both being present on the same metuloid. Similar crystals and granules are present on portions of the context hyphae. Because of the bright colour of granules, metuloids are readily seen in sections. According to E. M. Wakefield granules are soluble in alkalies, producing a bright yellow solution.

TYPE LOCALITY: Rotorua, Auckland, New Zealand.
