Description

Fruiting body (Fig. 2 ): Basidiocarps perennial, pileate to pendent, hard corky and without odour or taste when fresh, woody hard and medium in weight when dry; pilei irregular, projecting up to 8 cm, 4 cm wide and 3.5 cm thick at base; pileal surface black to dark brown at the margin, narrowly concentrically sulcate, glabrous, with a very hard black crust 1-5 mm thick; margin obtuse. Pore surface greyish-brown when fresh, becoming deep olive when dry; sterile margin yellowish-brown, up to 2 mm wide; pores circular to angular, 5-8 per mm; dissepiments thin, more or less entire to slightly lacerate; tubes woody hard, concolorous with pores, each layer up to 2 mm deep, white mycelial strands present in old tubes. Subiculum very thin to almost lacking.

Hyphal structure: Hyphal system dimitic; generative hyphae simple septate; skeletal hyphae dominant; tissue darkening but otherwise unchanged in KOH.

Tubes: Generative hyphae frequent, hyaline to pale yellow, thin- to slightly thick-walled, occasionally branched, frequently simple septate 1.5-2.5 μm in diam; skeletal hyphae golden yellow to pale brown, thick-walled with a wide to narrow lumen, unbranched, aseptate, interwoven, 2-3.5 μm in diam; setae and cystidioles absent; hymenium collapsed in the studied material, basidia and basidioles not seen; small or large rhomboid crystals abundant.

Spores: Basidiospores broadly ellipsoid, golden yellow, thick-walled, smooth, IKI-, CB(+), (4.1-)4.3-4.7(-4.9) × (3-)3.2-3.9(-4) µm, L = 4.50 µm, W = 3.42 µm, Q = 1.20-1.35 (n = 60/2) (Fig. 3 ).

Etymology

Crystallina , referring to the species having abundant crystals.
