　Description： Basidiocarp resupinate, effuse, adnate, membranaceous, 50-150 μm thick in section. Hymenial surface clay-yellow or buff-colored, smooth, occasionally cracked; margin thinning, paler, filamentose. Hyphal system monomitic; hyphae nodose-septate. Subiculum composed of a thin basal layer and a medullary layer which makes up a fairly loose texture; hyphae colorless, 2.5-4.5 μm diam., generally thin-walled, basal hyphae occasionally slightly thick-walled. Hymenial layer with dense texture; hyphae colorless, mainly vertical, thin-walled. Gloeocystidia numerous, colorless or slightly yellow, cylindrical or clavate, with stalked bases, terminal or lateral, 40-60 × 8-20 μm, slightly thick-walled, SA＋. Lamprocystidia not adundant, apically encrusted, colorless, 35-55 × 6-9 μm (encrustation included), with 0.7-1.5 μm thick walls. Basidia subclavate, 28-38 × 5.5-6.5 μm, 4-sterigmate. Basidiospores narrowly ellipsoid, adaxially slightly concave, smooth, thin-walled, (7.5-) 8-9 (-9.2) × 3-3.7 μm, IKI－, CB －.

　Note： This species belongs to the subgenus Gloeopeniophora (H?hn. & Litsch.) Boidin & Lanq., due to having numerous gloeocystidia and lacking brown hyphae in the basidiocarp. Peniophora subsalmonea Boidin, Lanq. & Gilles seems to be the most closely allied species owing to resemblance of general morphological features (Boidin et al. 1991). However, it can be distinguished from P. formosana by several characteristics. Firstly, Peniophora subsalmonea is a tropical species, reported from Reunion Island in the Indian Ocean, while the collection of P. formosana was made from high mountain temperate belt above 2,000 m altitude of Taiwan. Secondly, lamprocystidia of P. subsalmonea are shorter and wider (25-38 x 10-16 (-20) μm compared to 35-55 x 6-9 μm in P. formosana). Thirdly, gloeocystidia of P. subsalmonea are distinctly thick-walled except the thin-walled apical parts, and sometimes pointed at apices. Gloeocystidia of P. formosana are slightly thick-walled, and obtuse at apices. Moreover, basidiospores of P. subsalmonea are smaller ((6.5-) 7-8.2 x 2.5-3.2 μm, according to Boidin et al. 1991) than those of P. formosana ((7.5-) 8-9 (-9.2) x 3-3.7 μm).
