Descriptions
CONIFERAE. Pinus ponderosa: Auckland, Rotorua State Forest, 400 m. Pinus radiata: Auckland, Atiamuri, 450 m; Pinedale, 500 m.
Hymenophore annual, arid, membranous, adherent, effused forming linear or irregular areas to 15 x 10 cm; hymenial surface straw colour or pallid ochre, at first somewhat punctulate, becoming stellately creviced; margin thinning out, adherent, straw colour, arachnoid, sometimes irregularly porose-reticulate. Context straw colour, 90-130 µm thick, basal layer of a, few stout repent hyphae, intermediate layer of loosely intertwined, widely branched, frequently anastomosed hyphae more densely arranged in the subhymenium; generative hyphae 5-7 µm diameter, walls 0.5-1 µmthick, becoming thinner in the subhymenium, naked, with large often proliferating clamp connections. Gloeocystidia arising from the base of the context and beneath the hymenial layer, some projecting to 90 µm, flexuous-cylindrical, 64-150 x 8-14 µm. Hymenial layer to 50 µm deep, a loose palisade of basidia, paraphyses, and gloeocystidia. Basidia subclavate, 20-35 x 6-8 µm, bearing 4 spores; sterigmata slender, to 7 µm long. Paraphyses subclavate, 12-22 x 5-6.5 µm. Spores oval, obovate, subglobose, a few elliptical, apiculate, 6-9 x 5.5-7 µm, walls delicately verruculose, hyaline; 0.75-1 µm thick, staining deeply.
DISTRIBUTION: Europe, Great Britain, North America, South Africa, New Zealand.
HABITAT: Effused on bark of decayed fallen trunks.
Spores may be globose, subglobose, oval, obovate, or elliptical, and are delicately verruculose, thick walled, and stain deeply with aniline blue. Many are scattered among the context hyphae. Gloeocystidia are flexuous-cylindrical and arise from the base of the context and beneath the hymenium, some of the latter projecting to 90 µm. Paraphyses are subclavate and often develop at a wide angle. Clamp connections are large and frequently proliferating.
TYPE LOCALITY: South Carolina, U.S.A.
