Descriptions
Aleurodiscus limonisporus D.A. Reid 1956 [1955]
FAGACEAE. Nothofagus cliffortioides: Wellington, Whakapapa Valley, Mt. Ruapehu, 1,100 m; Mangatorutoru Stream, Mt. Ruapehu, 1,000 m; Whakapapaiti Stream, Mt. Ruapehu, 1,250 m; Chateau, Mt. Ruapehu, 1,100 m. Nelson, Lake Rotoiti, 700 m. Nothofagus cunninghami: Victoria, Cumberland Falls (type collection, herb. Kew). Nothofagus fusca: Auckland, Upper Mohaka River, 700 m. Wellington, Blyth Track, Mt. Ruapehu, 1,500 m. Nelson, Murchison, 140 m; Orwell Creek, Ahaura; Totara Flat; Granville Forest.
Hymenophore annual, ceraceous, at first developing as numerous small orbicular or irregular disciform colonies with free margins and attached by broad bases, 2-10 mm diameter, soon connate and extending to form irregularly linear areas to 15 x 3 cm; exterior surface tan, tomentose with convoluted hairs; hymenial surface even, ridged at points of coalescence, at first cream, soon pallid flesh pink or salmon, not creviced. Context white, to 0.5 mm thick, of radiately arranged parallel hyphae densely compacted and partly cemented at margins, embedding crystals in the base; generative hyphae 5-6 µm diameter, walls 1-1.5 µm thick, without clamp connections. Gloeocystidia arising from the base and penetrating the hymenial layer, not projecting, flexuous-cylindrical, to 160 x 10 µm. Hymenial layer to 150 µm deep, a dense palisade of basidia, paraphyses, pseudophyses, and gloeocystidia. Basidia subclavate, 60-130 x 16-26 µm, bearing 4 spores; sterigmata arcuate, subulate, to 16 µm long. Paraphyses cylindrical, or with slightly expanded apices, 48-100 x 7-10 µm. Pseudophyses cylindrical, slightly projecting, often bent or angled, some forked, 4-6 µm diameter. Spores citriform, or elliptical and biapiculate, 16-24 x 12-16 µm, walls smooth, hyaline, 0.25 µm thick, amyloid.
DISTRIBUTION: Australia, New Zealand.
HABITAT: Scattered or connate on bark of dead fallen branches.
Collections vary in surface colour, spore size, diameter of hyphae and thickness of their walls. The species may be separated from others with disciform pilei by the large citriform spores, large basidia, and reticulated surface of the hymenium. Reticulations are produced by ridges formed at points of coalescence of individual colonies. A. limonisporus is confined to species of Nothofagus.
TYPE LOCALITY: Cumberland Falls, Victoria, Australia.
