Vararia investiens (Schwein.) P. Karst. 1898
MYRTACEAE. Eucalyptus globulus. Nelson, Appleby, 35 m. Leptospermum scoparium: Auckland, Moturoa, Bay of Islands, 20 m; Paratai, Whangarei, 150 m; Rangitoto Island; Waikowhai, 20 m; Swanson, 100 m; Mt: Te Aroha, 400 m. PROTEACEAE. Hakea acicularis: Auckland, Campbells Bay, 35 m. SCROPHULARIACEAE. Hebe salicifolia: Auckland, Rangitoto Island. VERBENACEAE. Vitex lucens: Auckland, Thumb Track, Little Barrier Island. UNKNOWN HOSTS. South Australia, Bakers Gully, Clarendon. New South Wales, Sydney; Hornsby; National Park.
Hymenophore annual, membranous, adherent, effused forming linear areas to 10 x 3 cm, with numerous irregular outlying islands; hymenial surface ochre, resembling new chamois leather, often prumose, finely irregularly tuberculate, or even, not creviced; margin thinning out, concolorous, fibrillose, adherent. Context 60-150 µm thick, yellow ochre, basal layer narrow, of parallel hyphae, intermediate layer of branched and intertwined hyphae embedding masses of dichophyses; generative hyphae 3.5-4 µm diameter, walls 0.2 µm thick, naked, with clamp connections. Gloeocystidia scanty, confined to the hymenial region, fusiform, 24-35 x 5-6 µm, sometimes slightly projecting, walls occasionally encrusted in part with gelatinous granules. Dichophyses yellow-brown, arranged in several vague layers, repeatedly branched, sometimes dichotomously, ends acuminate. Hymenial layer to 40 µm deep, a scanty palisade of basidia, paraphyses, gloeocystidia, and dichophyses. Basidia cylindrical or ventricose-cylindrical, 16-24 x 5-7 µm, bearing 4 spores; sterigmata erect, slender, to 8 µm long. Paraphyses scanty, subclavate, 10-18 x 4-5 µm. Spores fusiform, or clavate-fusiform with bluntly rounded apices and long acuminate bases, 9-11 x 3-4 µm, walls hyaline, smooth, 0.2 µm thick.
DISTRIBUTION: North and South America, Europe, West Indies,. Japan, Australia, New Zealand.
HABITAT: Effused on bark of dead branches.
Identified readily by the yellow-ochre colour of the hymenial surface, which resembles new chamois leather, and masses of yellow-brown dichophyses in the context and hymenial layer. Spores, present in only two of the collections listed, in shape resemble those of V. fusispora (Fig. 54). Collections have somewhat larger and more densely branched dichophyses than those of specimens examined in Kew herbarium, but in other features agree closely.
TYPE LOCALITY: Pennsylvania, U.S.A.
