 Description： |
Basidiocarp effuse, adnate, membranaceous when young, subceraceous when old, 50-130 μm thick in section (aculei excluded). Hymenial surface whitish and grandinoid when young, odontioid-hydnoid and ivory yellow when old, rarely cracked; margin paler, thinning, arachnoid- pruinose. Aculei varible in density and in size due to different developmental degree; separate when young, sometimes fused at bases when old, 4-12 per mm, conical when young, subulate when old, with obtuse or ± acute apices, up to ca. 800 × 200 μm. Hyphal system monomitic; hyphae nodose-septate. Subiculum fairly uniform, composed of medullary layer. Basal layer occasionally present in old fruit bodies. Medullary layer with fairly loose texture when young, fairly compact when old; hyphae hyaline, ± tortuous, 1.5-3.3 μm in diam, with 0.4-0.9 μm thick walls, the walls sometimes indistinct. Subhymenium not clearly differentiated, ± thickening, hyphae more vertical and narrower than those of subiculum. Trama with compact texture, hyphae more vertically arranged than those in subiculum. Cystidia numerous, projecting for approximately half their lengths, usually capitate, 14-32 × 2.7-3.5 μm, thin-walled. Basidia clavate, 11-22 × 3.5-4.5 μm, 4-sterigmate. Basidiospores allantoid, smooth, thin-walled, sometimes with several small oil-drops, (4-) 4.3-5.3 × 1-1.4 μm, IKI–, CB–. |

| Note： |
Taxonomic placement of this species was not certain among mycologists. Hjortstam and Bononi (1987) established a monotypic genus, Skvortzovia Bononi & Hjortst., for O. furfurella. Considering the close similarity of this species to Resinicium meridionale (Burds. & Nakas.) Nakas. in their cultural studies, Nakasone (1990) transferred it to the genus Resinicium. Resinicium was delimited by Wu (1990) as species with both astrocystidia and cyanophilic halocystidia. If Wu`s concept of this genus is adopted, both Mycoacea meridionalis Burds. & Nakas. and O. furfurella do not fit the circumscription of this genus. Morphological features of O. furfurella, such as the color and consistency of fruit bodies, as well as hyphal nature, capitate cystidia and allantoid basidiospores are very typical of the genus Jacksonomyces, even if the hymenial surface of this species is grandinioid to odontinoid- hydnoid. |
