Hymenophore pileate, annual, coriaceous, commonly solitary, often gregarious, rarely caespitose. Pilei usually flabelliform or spatulate, sometimes infundibuliform with one side split to the base, 2-4 cm tall, 8-20 mm wide; pileus surface bay, bright chestnut or sometimes ferruginous, even or radiately sulcate, concolorous or as often banded with darker zones either radiately or transversely; sometimes silky and with scattered surface hairs, more abundant in the darker zones and towards bases of pilei; margin thinning out, crenate, sometimes deeply incised; hymenial surface even, when fertile white and appearing farinose, creviced when old, radiately sulcate. Stems arising from bay, prominent mycelial discs, to 8 x 1 mm, finely velutinate, bay or umber. Context isabelline or wood colour, 0.2-0.6 mm thick, composed of radiately arranged parallel hyphae; with a coloured cortex; skeletal hyphae 4-4.5 µm diameter, lumena capillary; generative hyphae 3-3.5 µm diameter, walls 0.2 µm thick, with clamp connections. Gloeocystidia arising from the base of the subhymenium, traversing the hymenium but not projecting, some lying among the context hyphae, cylindrical or ventricose-cylindrical, sometimes flexuous and moniliform, 40-96 x 8-12 µm. Hymenial layer to 160 µm deep, a dense palisade of basidia, paraphyses, gloeocystidia, and paraphysate hyphae. Basidia subclavate, 16-25 x 5-6 µm, bearing 1-2-4 spores; sterigmata slender, erect, to 4 µm long. Paraphyses subcylindrical, 8-20 x 4-5 µm. Paraphysate hyphae scanty or abundant, cylindrical, 3 µm diameter, projecting to 10 µm, sometimes submoniliform. Spores oval or broadly elliptical, a few subglobose, 4-4.5 x 3-3.5 µm, walls smooth, hyaline, 0.2 µm thick.
DISTRIBUTION: East Indies, South Africa, New Guinea, Australia, New Zealand.
HABITAT: Usually solitary on decorticated decayed wood lying upon the forest floor.
Specific characters are the scattered and scanty often moniliform abhymenial hairs, woody context, deep hymenial layer containing abundant long and narrow gloeocystidia, small oval or broadly elliptical spores, spatulate or flabelliform pilei attached to broad mycelial discs, and habitat. In several features the species varies appreciably. Depth of the hymenial layer, and consequent length of gloeocystidia, is affected by position, becoming deeper, and gloeocystidia larger, from apices to bases of pilei. Abhymenial hairs may be scanty or relatively plentiful, solitary or arranged in small tufts. Often submoniliform, they are usually arranged in bands which traverse pilei laterally. Pilei are usually flabelliform or spatulate; occasionally they may be infundibuliform or campanulate, with one side split. Stems are attached to broad mycelial discs; sometimes two or three arising from the same disc. Surfaces may be concolorous or show lateral bands of darker brown. Spores are usually oval or broadly elliptical, without apiculi, and measure 4-4.5 x 3-3.5 µm. One of the collections was named by Cooke as S.obliquum Berk. & Mont.; several others were misnamed by Lloyd as S. sowerbeii, S. elegans, and S. surinamense.
TYPE LOCALITY: Sumatra.
