CONIFERAE. Dacrydium cupressinum: Westland, Weheka, 200 m, type collection, P.D.D. herbarium, No. 17428.

Hymenophore annual, arachnoid, adherent, effused forming irregular colonies to 4 x 2.5 cm; hymenial surface white, or cream, velutinate, not creviced; margin thinning out, white, arachnoid, adherent. Context to 50 µ thick, white, basal layer composed of a few repent hyphae, intermediate layer a compact zone of mainly erect hyphae; generative hyphae 4-6 µ diameter, walls 0.2 µ thick, naked, with clamp connections. Cystidia arising from the base of the context, projecting for the greater part of their length, cylindrical, 56-90 x 6-8 µ, apices inflated to 10 µ, walls smooth save beneath inflated regions there bearing a band of coarse crystals, lumena capillary, save in inflated apical regions. Hymenial layer a scanty palisade of basidia, paraphyses, cystidia, and a few paraphysate hyphae. Basidia clavate, 12-16 x 5.5-6 µ, bearing 4 spores; sterigmata erect, slender, to 4 µ long. Paraphyses clavate, 10-14 x 4-5 µ. Paraphysate hyphae arising from the context, projecting slightly, stems to 12 x 3 µ, capitate apices 4-5 µ diameter. Spores elliptical, 4-4.5 x 3-3.5 µ, walls smooth, hyaline, 0.1 µ thick.

TYPE LOCALITY: Weheka, Westland, New Zealand.
DISTRIBUTION: New Zealand.

HABITAT: Effused on bark of dead branches.

Hymenophorum araneum, adnatum, effusum; superficie alba vel cremea, velutinata, non rimosa. Hyphae generatoriae fibulatae, 4-6 µ diam. Cystidia cylindricalia, 56-90 x 6-8 µ, apicibus ad 10 µ inflatis, cervice crassis crystalis cincta. Basidia clavata, 12-16 x 5.5-6 µ, 4 sporis. Sporae ellipticae, 4-4.5 x 3-3.5 µ, parietibus levibus, hyalinis. On dead bark of Dacrydium cupressinum, Weheka, Westland, N.Z.

Cystidia are cylindrical, apices inflated, with girdling bands of crystals at bases of inflated areas. Five species with inflated apices to the cystidia have been named, T. accedens (B. & G.) Donk, `Peniophora' juniperina Bourd. & Galz., T. regifica (Jacks. & Deardn.) Donk, T. sceptrifera (Jacks. & Were.) Donk and T. thermometra. T. cincta agrees most closely with T. regifica and T. sceptrifera. It differs from the latter by the shape of the cystidia, and from T. regifica by the smaller cystidia with bands of girdling crystals, and smaller spores.
