MIMOSACEAE. Acacia dealbata: Canterbury, Ashburton, 30 m. PINACEAE. Pinus radiata: Auckland, Woodhill, 120 m; Kaingaroa State Forest, 600 m, type collection, P.D.D. herbarium, No. 5691. UNKNOWN HOSTS. Victoria; Realesville. Tasmania, Port Arthur.

Hymenophore annual, coriaceous, compound, composed of numerous pilei (7-30) arising from a common base, frequently densely imbricated, sometimes rosetted. Pilei flabelliform or sometimes spatulate, 1-3 cm wide, 0 .5-2.5 cm radius, 2-5 mm deep, often laterally attached to one another, erect or horizontal; pileus surface fawn or bay with umber zones, radiately striate; without a cortex; margin acute, inturned, crenate, dentate; hymenial surface white or cream, even, sterile border to 2 mm wide. Pores in section white or cream, round, elongated or angular, decurrent, 5-7 per mm (3-4 per mm when decurrent), 100-250 µm diameter, to 1.5 mm deep; dissepiments 50-100 µm thick, equal, apices even or dentate. Context white, 0.25-1.5 mm thick, of closely compacted radiately arranged hyphae ; generative hyphae 5-6 µm diameter, walls 0.5-1.5 µm thick, freely septate, sparsely branched, with clamp connections, encrusted with mucilage granules; conducting hyphae 5-7µm diameter, walls 0.2 µm thick, sparingly septate, contents staining; Hymenial layer to 12 µm deep, a dense palisade of basidia and paraphyses partly embedded in mucilage. Basidia subclavate, 10-12 x 4-5 µm, bearing 4 spores; sterigmata erect, to 4 µm long. Paraphyses subclavate or subcylindrical, 6-10 x 3-5.4 µm. Spores broadly elliptical, oblong with rounded ends, or sometimes pip-shaped, 3.5-4 x 2-2.5 µm, walls smooth, hyaline, 0.2 µm thick.

New Zealand, Tasmania, Australia.

Caespitose upon fallen decayed logs, bases of stumps, soil on the forest floor, or burnt wood.

In its typical form the species may be recognised by the small, thin, flaccid coriaceous pilei, small pares, colour of pores and pilei, and small hyaline spores. Context hyphae bear numerous mucilage granules and are often embedded in mucilage, as are basidia and paraphyses. When decurrent, pore orifices are dentate, but are even elsewhere. Australian and Tasmanian specimens examined are lighter in colour, flabelliform rather than rosulate, but agree in microfeatures.
