POLYGONACEAE. Muehlenbeckia australis: Wellington, Kitchener Park, Feilding, 30 m. ROSACEAE. Rubus idaeus: Hawke's Bay, Hastings, 10 m. RUTACEAE. Citrus aurantifolia: Auckland, Avondale, 5 m. SOLANACEAE. Cyphomandra betacea: Auckland, Remuera, 80 m; Mt. Eden, 120 m.
Pilei annual, scattered or gregarious, membranous, at first subglobose, becoming disciform or pezizaeform, 0.25-1.25 mm diameter, attached by brief bases; exterior white, covered with a dense tomentum of abhymenial hairs which curve over the hymenium and fringe the substratum,, hairs filiform, 4-6 µm diameter, finely crystal encrusted; margin fimbriate, inturned; hymenial layer even, cream or pallid buff, concave. Context white, to 80 µm thick, of radiately arranged compact hyphae; generative hyphae 3-4 µm diameter, walls 0.25 µm thick, hyaline, tinted in a few outer hyphae. Hymenial layer to 80 µm deep, a dense palisade of basidia and paraphyses. Basidia subclavate, 50-80 x 11-14 µm, bearing 2-4 spores; sterigmata arcuate, slender, to 7 µm long. Paraphyses subclavate, 45-65 x 9-11 µm. Spores irregular, obovate, pyriform, limoniform, or triangular with rounded angles, often biapiculate, 12-17 x 9-11 µm, walls smooth, hyaline, 0.25 µm thick.
DISTRIBUTION: Europe, North America, New Zealand.
HABITAT: Scattered or crowded on bark of dead twigs.
Although close to L. villosa in macrofeatures, the species may be separated by the larger basidia and almost triangular spores with rounded angles and oblique apiculi. Only a few spores exhibit this feature, others being obovate, pyriform, or limoniform, often with two apiculi. In the original description the hymenial surface was said to be violaceous, but in collections examined in Kew herbarium, and those present in this region, it is cream or buff.
TYPE LOCALITY: Europe.
