Hymenophore annual, or biennial, coriaceous, pileate, sessile. Pilei commonly flabelliform or umbonate and attached by a narrow base, caespitose-Imbricate when several develop from a common resupinate base, less often applanate and dimidiate, sometimes effused-reflexed with a prominent resupinate basal area, rarely cupulate or infundibuliform, occasionally wholly resupinate when irregularly orbicular, 1-14 cm radius, 1-10 cm wide; pileus surface at first clothed with tan or bay tomentum, soon sulcate and zoned either with light and dark brown hairs, or zones in which the chestnut cortex is exposed, sometimes almost naked near margins, points of attachment, or both, often radiately crenulate or fluted; margins acute, plane, crenate, sometimes deeply lobed and occasionally lacerated, concolorous; hymenial surface ochre or pallid chestnut, showing similar concentric and/or radiate markings as the surface, scantily creviced when old, or even. Context straw colour, 0.2-0.4 mm thick, a dense layer of radiately arranged parallel hyphae, with a dense coloured cortex beneath abhymenial hairs, some of which are encrusted with granules of mucilage or often cemented into groups; skeletal hyphae 4-6 µm diameter, walls 1.5-2 µm thick, hyaline or tinted yellow in areas beneath the hymenium; generative hyphae 3-4.5 µm diameter, walls 0.5 µm thick, without clamp connections. Cystidioid hyphae penetrating the hymeneal layer and projecting slightly, with apices expanded to 8 µm, walls 2 µm thick, contents granular, occasionally discoloured in herbarium specimens. Hymenial layer to 70 µm deep, a dense palisade of basidia, paraphyses, and cystidioid hyphae. Basidia subclavate, 20-25 x 4-5 µm, bearing 4 spores; sterigmata slender, erect, to 5 µm long. Paraphyses subclavate or cylindrical, 16-20 x 3.5-4 µm. Spores narrowly elliptical, obliquely apiculate, 5-6 x 2-2.5 µm, walls smooth, hyaline, 0.2 µm thick.

DISTRIBUTION: Cosmopolitan.

HABITAT: Solitary or crowded on bark or decorticated wood of dead branches and trunks.

Following examination of collections in Kew herbarium and the abundant specimens available in Australia and New Zealand I am satisfied that S. fasciatum, S. lobatum, and S. ostrea are merely forms of one variable species. Types of S. perlatum ex Philippine Islands, S. concolor from Tasmania, and a Kew collection labelled S. leichkardtianum are also based on this one species. In the region are found specimens similar to those upon which Burt (1920b, pp. 155, 163) attempted to separate S. fasciatum from S. lobatum. According to latitude, altitude, and age they exhibit varying growth conditions, from flabelliform through effused-reflexed to resupinate, and degree of hairiness of the surface, ranging from tomentose to almost naked. Typical plants are large, lobed, and zoned with naked and tomentose concentric areas. Plants collected while young, or from mountain areas, may be smaller, more hirsute, often effused-reflexed and frequently resupinate. It is therefore not possible to maintain the two species on macrofeatures, and in microfeatures they are identical. In a previous paper (Cunningham, 1956b, p. 218) the species was described under the name of S. lobatum. It appears that the most likely epithet for the species is S. fasciatum, since this was the first applied valid name, so far as is at present known, and the type is extant.
