Pulcherricium caeruleum (Lam.) Parmarsto, Consp. Syst. Cort. p. 133. 1968..
Description：
Basidiocarp resupinate, effuse, margins recurved, adnate when young but somewhat separative when old, ca. 100-250 μm thick in section, membranous, Hymenial surface Light Olive-Gray, Pale Green-Blue Gray, Clear Green-Blue Gray, Deep Green-Blue Gray to Dark Green-Blue Gray (color names are from Ridgway, 1912), immature specimen lacking shelter of non-tinted hymenium, thus exposing the Plum Purple subhymenium and upper subiculum, even or slightly tuberculate, usually cracked when mature, and even cleaved into pieces when old; margin separate and recurved when mature, usually concolorous or paler. Subhymenium and upper context region tinted with a blue-purple secretion produced by it self. Hyphal system monomitic; hyphae distinct, septae clamped, 2-5 μm wide, with thin to slightly thickened walls of up to ca. 1 μm thick, hyaline or subhyaline. Subiculum textura intricate, without distinct basal layer. Basidioles 15-40 × 3-7 μm, have tortuous tendency and sometimes splitting on the top, thus similar to branched hyphidia (or dendrohyphidia); occasionally the branch is separated by a septa or discolored to blue. Basidia clavate, with a tapering base, 30-40 × 5.5-9 μm. Basidiospores subglobose or broadly ellipsoid, thin-walled, hyaline or rarely tinted bluish, 7.5-10.5 × 5.5-7.5 μm, IKI–, CB–.
