Cupressus macrocarpa Hartn. Auckland: Cornwallis, 50ft, September, 1953, J.D. Atkinson. Dacrydium cupressinum Sol. Auckland: Pureora, G.B. Rawlings.

Hymenophore annual, membranous, adnate, effused forming numerous elliptical colonies 2-18 x 2-3 cm; hymenial surface at first ochre, then chestnut, finally olivaceous towards the centre, even, minutely velutinate, tardily areolately creviced; margin thinning out, arachnoid-fibrillose, cream or pallid ochre, adnate, forming a broad border 2-10 mm wide. Context cream to ochre, 200-750 µ thick, of woven hyphae not differentiated into intermediate and basal layers; hyphal system monomitic; generative hyphae 2.5-4 µ diameter, walls 0.5 µ thick, hyaline, freely branched and septate, sometimes inflated between septa, without clamp connexions. Hymenial layer to 95 µ deep, a close palisade of basidia, paraphyses, gloeocystidia and paraphysate hyphae. Basidia subclavate, projecting, 35-50 x 8-10 µ, 4-spored; sterigmata arcuate, to 6 µ long. Paraphyses subclavate, about half the length and diameter of the basidia, sometimes cylindrical and acuminate. Gloeocystidia arising in the base of the hymenium, when projecting to 40 µ, and at different levels in the context, cylindrical, often strangulated near the apices, 70-95 x 8-12 µ, walls hyaline, naked, 0.25 µ thick. Spores subglobose, oval, elliptical, or obovate, 12-18 x 8-11 µ, with rounded apices and apiculate bases; walls smooth, fuscus, 0.75-1 µ thick.

TYPE LOCALITY: North Island, New Zealand.
DISTRIBUTION: New Zealand.

HABITAT: Effused on bark of dead branches and trunks.

Specific features are the hyaline generative hyphae, conspicuous hyaline gloeocystidia, large spores, effused adnate colonies with pallid broad margins and the central area becoming olivaceous and creviced. Spores may range in shape from subglobose to obovate, reach a length of 18 µ, and walls may become thickened to 1 µ. Gloeocystidia are abundant, naked, project for about half their length, aseptate, thin walled and possess contents which stain deeply with aniline blue. They exhibit all features of similar organs present in certain species of Corticium and Peniophora, so are regarded as gloeocystidia and not cystidia. Occasional hyphae are inflated between septa, a condition also present in C. betulae, C. minor and C. olivacea. Paraphysate hyphae occur in the hymenial layer of actively developing specimens and, as plants age, collapse and tend to disappear.
Although Massee (1906, 30) stated that there was no specimen of Corticium viride in Kew herbarium, the type, ex "North Island, N.Z., Colenso" is present nevertheless, filed under the cover of Coniophora viridis. Portion of the same collection has been placed under the cover of Thelephora viridis (= Tomentella viridis (Berk.) G.H. Cunn.). Massee (1889, 130) stated that spores were 25-30 x 17-20 µ, an error later compiled by Cooke in his "Handbook of Australian Fungi" (1892, 195).
