　Description： Basidiocarp effuse, adnate, membranaceous, 120-350 µm thick in section. Hymenial surface Pinkish Buff to Light Pinkish Cinnamon, smooth, cracked extensively and exposing white filamentose subiculum; margin usually recurved, sometimes ceraceous and deeper in color. Hyphal system monomitic; hyphae nodose-septate. Subiculum uniform, composed of medullary layer, with rather loose texture; hyphae ± horizontal, somewhat vertical near subhymenium, loosely interwoven, colorless, rather distinct, slightly tortuous, guttulate, 2.5-4.5 μm diam., thin- or slightly thick-walled. Cystidia numerous, usually slightly projecting, cylindrical with acute apices, slightly flexuous, 40-60 × 5-7 μm, thin-walled, apically CB+. Basidia narrowly clavate, slightly flexuous, 40-50 × 6-7 μm, 4-sterigmate. Basidiospores pyriform or ellipsoid, with an oblique and prominent apiculus, with homogeneous contents, 8.7-10.2 × 4.3-5.5 μm, sometimes agglutinated in tetrads, IKI-, CB- or slightly CB+.

　Note： The species was well known as Cylindrobasidium evolvens (Fr.:Fr.) Jül., but a change in the International Code of Botanical Nomenclature enacted at Sydney in 1981 made reconsideration necessary. Corticium laeve Pers.:Fr. was the oldest name of this species and the necessary new combination was therefore made by Chamuris (1984).
