UNKNOWN HOSTS. Queensland, Dunk Island (As Stereum percome, herb. Kew); Stannary Hills (As S. amaenum, herb. Kew).

Hymenophore annual or biennial, coriaceous, loosely attached, patelliform with raised margins, narrowly effused-reflexed, sometimes resupinate, 1-3 cm across, or fused to form irregular areas 3-8 cm long. Pilei merely reflexed margins, to 0.5 cm broad, surface densely tomentose, concentrically zoned, dingy white, straw colour, or tan; hymenial surface ferruginous, umber, or purple towards the centre, tuberculate or rugulose, deeply radially creviced; margin thinning out, fibrillose, grey becoming tan. Context ferruginous, 0.2-0.75 mm thick, of hyaline parallel hyphae radiately arranged, cortex ferruginous, of intertwined partly cemented hyphae, ends of skeletal hyphae forming a dense palisade of cystidioid hyphae beneath the subhymenium, some penetrating the hymenial layer, expanded to 8 µm, densely encrusted with brown mucilage granules; skeletal hyphae 4-6 µm diameter, walls 1-2 µm thick; generative hyphae 2.5-4 µm diameter, walls 0.5 µm thick, naked, without clamp connections. Metuloids arising in the hymenium and subhymenium, some projecting to 30 µm elliptical or lanceolate, 32-60 x 12-16 µm, walls coarsely encrusted with crystals. Hymenial layer to 35 µm deep, a close palisade of basidia, paraphyses, metuloids, and cystidioid hyphae. Basidia subcylindrical, or subclavate, 20-26 x 4-5 µm, bearing 4 spores; sterigmata erect, slender, to 4 µm long. Paraphyses cylindrical, 18-22 x 3.5-4 µm. Spores elliptical, 4.5-5 x 2.5-3 µm, walls smooth, hyaline, 0.2 µm thick.

DISTRIBUTION: East Indies, Ceylon, India, Pakistan, Burma, Australia.

HABITAT: Loosely attached to bark of dead branches.

In a former paper (1953, p. 289) following Cooke I referred a Queensland specimen in Kew herbarium to Peniophora papyrina. From this species Reid has shown that L. papyracea may be separated by the presence in the hymenium and subhymenium of a palisade of cystidioid hyphae, densely encrusted with brown mucilage granules soluble in aqueous solutions of potassium hydroxide. Spores are rare in the specimens examined, a few only attached to basidia being of the dimensions given, although they may not have reached full size. The type of S. percome from Ceylon in Kew herbarium was found to be of this species. S. corruge was based on a stratose specimen.

TYPE LOCALITY: Java.
