 Scientific Name: Phanerochaete aculeata

Phanerochaete aculeata Hallenb., Iranian J. Pl. Pathol. 14: 62. 1978.

 Description: Basidiocarp effuse, ± adnate, ceraceous when old, 170-450 μm thick in section (aculei excluded). Hymenial surface Ivory Yellow, Cartridge Buff or Light Buff when young, Warm Buff when old, no color changes in KOH, locally grandinioid, odontioid, or raduloid, cracked; margin white, thinning, pruinose or arachnoid-byssoid. Aculei sparse or abundant, occasionally fused, irregularly cylindrical, with obtuse apices, up to ca. 1 mm long. Hyphal system monomitic; hyphae simple-septate. Subiculum uniform, composed of medullary layer, with ± loose to rather dense texture; hyphae somewhat horizontal next to substratum, ± vertical elsewhere, moderately ramified, colorless, distinct, rather straight, 3-9 μm diam., with 1-2.5 μm thick walls, covered with scattered and minuterectangular crystals, which dissolve easily in KOH, anastomoses occasional. Hymenial layer distinctly differentiated, with compact texture, thickening; hyphae vertical, colorless, strongly agglutinated, distinctly narrower than those of subiculum, thin-walled. Tramal hyphae similar to subicular hyphae, with more compact and vertical arrangement. Cystidia variably abundant, usually slightly projecting, sometimes sparsely encrusted, tubular or cylindrical, usually basally narrow, slightly flexuous, 40-80 × 5.5-7 μm , thin- or slightly thick-walled. Basidia narrowly clavate, slightly flexuous, 22-33 × 3.8-4.5 μm, 4-sterigmate. Basidiospores ellipsoid or cylindrical, sometimes with oil-drops, smooth, thin-walled, (4.5-)5-6.3(-7) × 2.2-3 (-3.2) μm, IKI-, CB-.

 Note: The Taiwanese collection differs from the type specimen of Phanerochaete aculeata in (1) the stouter and sometimes raduloid aculei of the hymenial surface, (2) the thicker walls of its subicular hyphae, and (3) the presence of smaller rectangular crystals on the subicular hyphae. However, these differences fall within the acceptable range of variation of a species. Identification of the Taiwanese specimen was kindly confirmed by Dr. Nils Hal-lenberg.
