COMPOSITAE. Brachyglottis repanda: Auckland, Waiomu Valley, Thames, 35 m. MYRTACEAE. Leptospermum scoparium: Auckland, Glen Esk Valley, Piha, 300 m. RANUNCULACEAE. Clematis paniculata: Wellington, Lake Papaitonga, 20 m. VIOLACEAE. Melicytus ramiflorus: Wellington, Lake Papaitonga, 20 m.
Hymenophore annual, membranous-cretaceous, adherent, consisting of numerous pulvinate colonies of irregular shape, 1-4 mm across, which may be scattered or crowded, loosely attached by a broad base, sometimes coalesced to form irregular areas to 3 cm across; hymemal surface chalk white, pruinose, usually slightly convex, even, not creviced; margin definite, free, rounded, white. Context white, 0.5-0.75 µm thick, of several vague layers, basal layer of mainly parallel hyphae densely intertwined, intermediate layer of erect hyphae partly cemented to form a coarsely cellular tissue, lacunae of which are packed with masses of crystals save at the base of each layer; generative hyphae 2.5-4 µm diameter, walls 0.2 µm thick, without clamp connections. Dendrophyses arising in the base of the intermediate layer, composed of slender hyphae 1.5-2 µm diameter, branched apically and densely encrusted with fine crystals. Gloeocystidia absent. Hymenial layer to 60 µm deep, a scanty palisade of basidia, paraphyses, and dendrophyses. Basidia subclavate, 60-75 x 12-18 µm, bearing 4 spores; sterigmata arcuate, subulate, to 16 µm long. Paraphyses cylindrical, fusiform, or obclavate, 22-40 x 6-9 µm. Spores globose or subglobose, apiculate, 14-18 x 13-16 µm, walls smooth, hyaline, 0.2 µm thick, nonamyloid.
DISTRIBUTION: North America, Jamaica, New Zealand.
HABITAT: Scattered or crowded on bark of living trunks.
Collections agree with authentic specimens of 'Aleurodiscus' candidus examined in Kew herbarium. The species may be identified by the pulvinate, chalk white, usually scattered fructifications of irregular shape, vaguely zoned context, delicate crystal-encrusted dendrophyses, and globose, apiculate, smooth, nonamyloid spores. Dendrophyses are composed of slender hyphae, not exceeding 2 µm in diameter, with apices branched, branches being either continuous or again branched, the whole forming irregular clusters at the surface of the hymenial layer. The context is composed of several layers in which hyphae become cemented into a coarsely cellular tissue, lacunae of which are filled with masses of crystals.
TYPE LOCALITY: North Carolina, U.S.A.
