Lopharia areolata G. Cunn. 1963

CUNONIACEAE. Weinmannia racemosa: Westland, Lake Mapourika, 100 m, type collection, P.D.D. herbarium, No. 5100; Rimu, 50 m. Otago, Niagara, Catlins, 35 m. ICACINACEAE. Pennantia corymbosa: Hawke's Bay, Turangakumu Saddle, 850 m. PITTOSPORACEAE. Pittosporum rigidum: Wellington, Mt. Ruapehu, 1,100 m. SAXIFRAGACEAE. Carpodetus serratus: Auckland, Rangemore Track, Waitakere Ranges, 300 m. Hawke's Bay, Turangakumu Saddle, 850 m. VIOLACEAE. Melicytus ramiflorus: Auckland, Alfriston, 35 m.'
Hymenophore annual, membranous, forming irregular areas either in the form of numerous colonies with reflexed upper margins, when 2-5 cm across, or as linear resupinate areas to 30 x 3 cm with reflexed lateral margins. Pilei effused-reflexed, sometimes reduced to upturned edges, to 5 mm radius, length of the fructifications; surface straw colour, pallid ochre with tan or reddish-brown margins, bearing coarse hairs either in strigose tufts, or imbricately, edges lobed or torn, often incurved; hymenial surface cream, then alutaceous, even, becoming deeply areolately creviced. Context white, 250-400 µ thick, of mainly parallel hyphae and a deep subhymenium containing metuloids; without a cortex; generative hyphae 4-6 µ diameter, walls 0.2-1 µ thick, naked, without clamp connections. Metuloids crowded in the hymenium and subhymenium, forming a layer to 160 µ deep, of 3-7 overlapping rows, in thick specimens occupying the greater part of the context, some projecting to 20 µ, cylindrical with rounded apices, or subfusiform with acuminate apices, some flexuous, 30-65 x 7-9 µ, encrusted throughout, more coarsely below, the brief pedicels naked. Hymenial layer to 50 µ deep, a close palisade of basidia, paraphyses, and metuloids. Basidia subclavate, 20-24 x 4-5.5 µ, bearing 2-4 spores; sterigmata erect, slender, to 5 µ long. Paraphyses subclavate or subcylindrical, 16-20 x 3-4.5 µ. Spores oblong-elliptical, a few narrowly obovate, apiculate, 6-8 x 3-3.5 µ, walls smooth, hyaline, 0.1 µ thick.
TYPE LOCALITY: Lake Mapourika, Westland, New Zealand.
DISTRIBUTION: New Zealand.
HABITAT: Bark of dead branches.
Pilei effuso-reflexi, ad 5 mm radium, saepe absentes vel resupinatus est; superficie straminea vel pallide ochracea, pilis in cristis strigosis vel imbricata. Superficies hymenii cremea deinde alutacea, deinde alte areolato rimosa. Hypharum systema monomiticum; hyphae generatoriae afibulatae, 4-6 µ diam. Metuloids cylindricalia, apicibus rotundis vel subfusiformia, apicibus acuminatis, 30-65 x 7-9 µ, crystallis tecta. Basidia subclavata, 20-24 x 4-5.5 µ, 2-4 sporis. Sporae oblongo-ellipticae, 6-8 x 3-3.5 µ, parietibus levibus, hyalinis. On dead bark of Weinmannia racemosa, Lake Mapourika, Westland, N.Z.
Of the three species with monomitic hyphal systems L. areolata may be identified by the delicate hymenophore, small metuloids with brief hyaline pedicels, and absence of clamp connections. The context of pileate specimens consists of a broad layer of mainly parallel hyphae from which arise the abhymenial hairs, bordered by a deep layer of erect hyphae containing the metuloids; in resupinate specimens the context is composed mainly of intertwined hyphae as in members of the Corticeae. Lower metuloids are more coarsely encrusted, crystals becoming progressively finer towards the surface.
