Resinicium bicolor (Alb. et Schwein.) Parm., Consp. Sys. Cort. p. 97. 1968.
Description：
Macroscopic characters: Baidiocarps resupinate, widely effused, adnate, 2–5 × 9–23 cm, 100–350 μm thick, ceraceous to cretaceous, pruinose, crossly creviced, white to light buff, not changing color in 5% KOH; margins thining out, tomentose, concolorous; spines mi-nutely protruding, conical, free, moderately dense, fimbriate or truncate at apex, about 100 μm high, 30–250 μm wide at base.
Microscopic characters: Basal layer of context composed of parallel gelatinized hyphae, often in stratification, and not easy to distinguish from the substrata, hyaline or opaque; intermediate layers of context thicker than basal layer, composed of conglutinated loosely interwoven hyphae, with crystals embedded and turning dark color after treated with 5% KOH and phloxine; hyphae 1.8–3.2 μm wide, thin-walled, smooth, sometimes covered with densely radiate crystals, with clamp connections; cystidia with two types, protruding on the hymenium and spine surfaces and immersed in context; one type with terminal globose shape, covered by loosely or densely radicate crystals, 5–18 μm in diam., with the pedicels 3–4 μm wide, sometimes constricted near the apex; the other with terminal swelling, never encrusted at the head, containing yellow materials and easily stained by phloxine, 5–10 μm in diam., with the pedicels 3–4 μm wide; hymenium composed of basidia, paraphyses and two types of cystidia, arranged in palisade; basidia clavate, 4.5–5 × 16–20 μm, with 2–4 basidiospores; sterigmata 4 μm long, straight; basidiospores ellipsoid, 3–3.5 × 4–5.5 μm, thin-walled, smooth, 1-guttulate, non-amyloid.
Specimens：
Taipei Hsien, Pinlin Hsiang, from Orchid Valley to Mt. Suchuanglo, on the road side, under the hardwood forests, 400–500 m, Dec. 7, 1975, S.-H. Lin (NTU-3139); Taipei Hsien, Mt. Seven-star, under the primary hardwood forests, alt. 700 m, Dec. 6, 1975, S.-H. Lin (NTU-3153).
Habitat：
On the dead twigs and stems of the broad-leaved trees, often associated with un-known parasitic fungi in the substrata, and also associated with white rot.
Distribution：
Europe, North America, New Zealand, USSR, Japan and Taiwan.

Note：
The two types of beautiful cystidia of the species are the diagnostic character by which this species can easily be separated from other known species of the genus. It is a cosmopolitan species.
