Hymenophore resupinate, annual, membranous, adherent, at first appearing as small orbicular scattered colonies 0.5-2 cm across, merging to form irregular linear areas 5-15 x 2-6 cm; hymenial surface reddish-brown, often with a purple tinge or purplish when old, even or irregularly roughened, finely velutinate, either without crevices, tardily creviced, or in old specimens sometimes exhibiting radiate series of crevices as in H. obesa; margin thinning out, fibrillose, loosely attached, narrow or broad, fulvous. Context ferruginous, 150-250 µm thick, of mainly parallel hyphae rather loosely arranged, cortex of cemented intertwined hyphae bearing abhymenial hairs of irregular length; skeletal hyphae 4-5 µm diameter, walls 0.5-1 µm thick, golden yellow; generative hyphae 2-2.5 µm diameter, walls 0.25 µm thick, hyaline. Setal layer 80-130 µm deep, of 2-5 crowded overlapping rows of setae embedded among erect skeletal hyphae and of one or two rows of larger, scattered and often distorted setae in the context; setae irregularly fusiform, a few subulate, some projecting to 40 µm, 40-70 x 6-10 µm (some in the context to 85 µm long), walls delicately verruculose at apices, rich chestnut with moderately narrow lumena. Hymenial layer to 25 µm deep, a close palisade of basidia and paraphyses. Basidia subclavate, 12-15 x 3-4 µm, bearing 2-4 spores; sterigmata slender, slightly arcuate, to 5 µm long. Paraphyses cylindrical, 8-12 x 3-4 µm. Spores allantoid, 4-5 x 1 µm, walls smooth, hyaline, 0.1 µm thick.
DISTRIBUTION: Ceylon, Australia, New Zealand.
HABITAT: Bark of dead branches and trunks associated with a white rot.
Collections agree in microfeatures with the type in Kew herbarium, ex "Central Provinces, Thwaites, No. 336". Many differ in being less brightly coloured, a feature without taxonomic significance. The species may be separated from others of this section by the small allantoid spores; small setae crowded into several overlapping rows, reddish-brown colour of the hymenial surface and fulvous margin. It is liable to confusion with H. plurimaesetae, differing in features discussed under the latter. Sometimes the cortex is suppressed where tissues are in contact with the substratum; but sections from the free peripheral region demonstrate its presence. Most collections were taken from upright dead trunks and saplings, when the upper margins become thickened to simulate rudimentary pilei.
TYPE LOCALITY: Ceylon.
