Description: 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.
Habitat: HABITAT: Scattered or connate on bark of dead fallen branches.
Distribution: DISTRIBUTION: Australia, New Zealand.
Notes: 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.
