Summary:
Diagnostic characters are the yellow color, the flat habit, and microscopically, the skeletal hyphae, and the conspicuous thick-walled incrusted cystidia. The description is derived from Gilbertson(1).
Auriporia aurea is known in BC from one collection (Ginns(28)). It has been found in OR, AB, SK, ME, NM, and NY, (Gilbertson).
Cap:
growing flat on wood with pore surface exposed, sterile margin colored as pore surface, radiately fimbriate (fringed)
Flesh:
up to 0.1cm thick, soft, drying to pale buff with darker resinous streaks
Pores:
2-4 per mm., circular and angular, "yellow when fresh, drying yellowish-buff to pale brownish"; tubal layer up to 0.3cm thick, with tramal tissue similar to flesh, hymenium and subhymenium drying darker and forming a distinct layer under 30x lens
Microscopic:
spores 5-8.5 x 3-4 microns, cylindric-elliptic, smooth, inamyloid, colorless; basidia 4-spored, 25-30 x 6-8 microns, clavate, with basal clamp; cystidia frequent in hymenial layer, 20-55 x 12-25 microns, projecting to 15 microns, "ventricose, thick-walled, usually capitately incrusted with coarse crystalline material", colorless, some branched at the base and appearing rooted; hyphal system dimitic: contextual generative hyphae 2-4 microns wide, colorless, thin-walled, with occasional branching and abundant clamp connections, contextual skeletal hyphae 2-3.5 microns wide, colorless, with thickened walls, without clamp connections but with occasional simple septa, "tramal hyphae similar, faint amyloid reaction visible in tramal tissue"
