| Description： |
Basidiocarp resupinate, effuse, adnate, submembranaceous-pruinose, 30-60 μm thick in section. Hymenial surface grey, smooth, rarely cracked; margin thinning. Hyphal system monomitic; hyphae simple-septate. Subiculum fairly uniform, with dense texture; hyphae ±horizontal near substratum, fairly distinct, colorless or subcolorless, 2-4 μm diam., thin- or slightly thick-walled. Hymenial layer not clearly differentiated from subiculum. Gloeocystidia numerous, immersed or emergent, colorless, usually basally swollen and with narrow apices, rarely clavate, containing yellow and shiny oily contents, 18-30 × 5-10 μm, thin- or slightly thick-walled, SA+. Basidia suburniform, 12-16 × 3.5-4.5 μm, 4-sterigmate. Basidiospores subglobose, with a distinct apiculus, aculeate (smooth in KOH), thin- or slightly thick-walled, 3.6-4.1 × 3-3.5 μm, with fairly homogeneous contents, IKI bluish black, CB–. | |||

| Note： |
Four characteristics can be used to distinguish Boidinia cana from the closely related B. propinqua. The Basidiocarp of B. propinqua is pale yellow, while that of B. cana is gray. Gloeocystidia of B. propinqua are much longer than those of B. cana, and the shape is cylindrical, not basally swollen and apically narrow as in B. cana. Basidiospores of B. propinqua are slightly smaller (3.3-4 × 2.7-3.2 μm, from holotype), and have a distinct oil-drop which is not present in those of B. cana. Furthermore, B. propinqua was found in Canada and USA (Hjortstam and Ryvarden 1988), while B. cana is known from subtropical Taiwan. | |||
