CORIARIACEAE. Coriaria arborea: Auckland, Mt. Te Aroha, 230 m; Rangitoto Island, 250 m. CORYNOCARPACEAE. Corynocarpus laevigatus: Auckland, Wattle Bay, coast. MYRTACEAE. Leptospermum ericoides: Wellington, Pangarara River, Mt. Tongariro, 700 m. UNKNOWN HOSTS. New South Wales, Thornleigh. Victoria, Cockatoo. Tasmania, Browns River; Cascades, Hobart.

Hymenophore annual, adherent, membranous, effused forming irregular areas 3-8 x 1-3 cm, 0.5-1 mm thick. Hymenial surface white or cream, even, not creviced; margin even, to 1 mm wide, white, fibrillose, adherent. Pores not in strata, angular, often oblique or irpiciform, 3-5 commonly 3-4 per mm, 100-250 µm diameter, to 1 mm deep; dissepiments not toothed, 75-200 µm thick, equal, apices finely velutinate. Context white becoming cream when dry, of closely intertwined hyphae a few encrusted, 100-200 µm thick; skeletal hyphae 3.5-4 µm diameter, walls to 1 µm thick, staining, aseptate, sparingly branched near ends; generative hyphae 2.5-3 µm diameter, walls 0.2 µm thick, branched, septate, with clamp- connections. Hymenial layer to 20 µm deep, a close palisade of basidia, paraphyses, and scanty paraphysate hyphae. Basidia clavate, 12-16 x 5-6 µm, bearing 4 spores; sterigmata arcuate, to 4 µm long. Paraphyses subclavate, some ventricose, 10-14 x 4.5-5 µm. Paraphysate hyphae irregularly ventricose, to 25 x 8 µm, sometimes wanting. Spores globose or subglobose, apiculate, 4-4.5 µm, or 4-4.5 x 3.5-4 µm, walls smooth, hyaline, 0.1 µm thick.

DISTRIBUTION: Australia, Tasmania, New Zealand.

HABITAT: Bark and decorticated wood of fallen branches and trunks, associated with a white rot.

Plants resemble P. versipora in hyphal structure and nature of the surface. They differ in the subglobose spores and, usually, absence of capitate paraphysate hyphae, although a few of the latter are occasionally found. In two collections are present the peculiar paraphysate hyphae "shaped like the foot of a stocking" described by Overholts and Lowe. In one collection they are abundant, in the other rare.

TYPE LOCALITY: Brandon, Vermont.
