CONIFERAE. Agathis australis: Auckland, Walkers Bush, Waitakere Ranges, 250 m. Dacrydium cupressinum: Wellington, Kelburn, 100 m.

Hymenophore resupinate; membranous, loosely attached, effused forming irregular areas to 10 x 5 cm; hymenial surface tan, bay, or ferruginous, at first even, becoming porose-reticulate with pores 1-2 per mm, edges entire or interrupted, folds to 0.5 mm tall; margin tan or ferruginous, fibrillose or as often with rhizomorphs. Context ferruginous, 0.2-0.5 mm thick, basal layer of hyaline and brown hyphae mostly parallel, intermediate layer of hyaline intertwined hyphae somewhat loosely arranged; generative hyphae when brown 5-9 µm diameter, when hyaline 3-5 µm, walls 0.5-1 µm thick, often collapsed, with one or two clamp connections at some septa. Hymenial layer to 50 µm deep, a close palisade of basidia and paraphyses. Basidia subclavate, 24-42 x 6-9 µm, bearing 4 spores; sterigmata erect, slender, to 5 µm long. Paraphyses subclavate, 16-35 x 4-6 µm. Spores broadly elliptical, obovate, often flattened on one side, 8-12 x 5-7 µm, walls smooth, pallid ferruginous, 0.25 µm thick.

DISTRIBUTION: Europe, Great Britain, North America, Ceylon, India, South Africa, New Zealand.

HABITAT: Effused on bark, decorticated wood- or wood debris.

Through the courtesy of L. Harmsen, Denmark, who kindly forwarded specimens, I have been able to recognise S. himantioides among collections present in this region. The species differs from S. lacrymans, to which it was referred as a variety by W. B. Cooke (1957a, p, 207) by structure, thin-walled hyphae of the context, and narrower spores.

TYPE LOCALITY: Europe.
