Phlebia heterocystidia Sheng H. Wu, Acta Bot., Fennica 142: 29. 1990.

 Description: Basidiocarp effuse, adnate, ceraceous, 60-200 µm thick in section (aculei excluded). Hymenial surface Pale Olive-Buff, odontioid, not cracked; margin paler, thinning, arachnoid-pruinose. Aculei separate, occasionally fused, 3-5 per mm, brownish, corneous when old, cylindrical, with obtuse or ±acute apices, 200-600 (-800) × 100-250 µm. Hyphal system monomitic; hyphae nodose-septate. Subiculum bi-layered. Basal layer with dense to compact texture, up to ca. 30 µm thick; hyphae horizontal, colorless or yellowish, ±agglutinated, slightly thick-walled. Medullary layer with ± dense texture when young, compact when old; hyphae ± vertical, richly ramified, colorless or yellowish, indistinct, strongly agglutinated when old, ± tortuous, 1.7-3.5 µm diam., thin- or slightly thick-walled. Hymenial layer somewhat differentiated; hyphae vertical, colorless, agglutinated, narrower and with thinner walls than those of medullary layer. Brown-yellow resinous material common throughout section, dissolving in KOH. Cystidia numerous, projecting for approximately half their lengths, cylindrical, slightly flexuous, 17.5-26.5 × 4-5 µm, slightly thick-walled. Halocystidia few, 10.5-21 × 3.5-4.5 µm, thin-walled; outer globules 3.5-5.5 µm diam., thin-walled. Basidia clavate, 15.5-21.5 × 4.5-5.5 µm, 4-sterigmate. Basidiospores ellipsoid, adaxially flattened, smooth, thin-walled, sometimes with several small oil-drops, (4-) 4.3-5.2 (-5.7) × 2.2-2.7 µm, IKI-, CB-.

 Note: This new species resembles Mycoacia pinicola John Erikss., but besides the halocystidia it also has numerous cylindrical cystidia, which can be distinguished from the halocystidia by their different shape and thicker walls.
