Subulicystidium harpagum

Ciri dan struktur

Differs from other Subulicystidium species by the cystidia which resemble a harpoon due to protruded backward pointing individual crystals and moderately large cylindric to allantoid basidiospores (5.7–8.2 × 2.2–3.0 µm). Basidiomata annual, effused, resupinate, soft and fragile, arachnoid, loosely adnate and easily separable. Hymenophore smooth, velutinous due to numerous protruding large cystidia, whitish. Margin not differentiated. system monomitic. All septa with clamps. Subiculum thin, with interwoven richly branched hyphae 2-3 µm wide, thin-walled to very slightly thick-walled, hyaline, often with rough surface because of slight encrustation. In the older fruit-body parts, encrustation represents an up to 1 µm thick sheath over the hypha. Subhymenium thin, with hyphae identical to those in subiculum. Cystidia subulate, 35–62 × 2.5–3.5 µm including encrustation, projecting up to 30 µm, without basal swelling, terminal or pleural, with thin to slightly thickened hyaline cell wall and outer hyaline crystal sheath covering the whole cystidium except the thin-walled, acuminate and particularly narrow, apex. Crystal protrusions on cystidium are formed like short rods that project backwards under acute angle, thus making cystidia resembling a harpoon. Basidia suburniform, 9–12 × 4.2–5.7 µm, thin-walled, with 4 sterigmata and a basal clamp, basally slightly encrusted. Basidiospores weakly allantoid, adaxial side concave, L=(4.5–)5.7–8.2(–8.7) µm, W=(2.0–)2.2–3.0(–3.3) µm, Q=(1.7–)2.1–3.4(–3.8), N=178/4, with minute apiculus, smooth, thin-walled, hyaline, often with two oil drops (one at each pole), negative in Melzer’s reagent.
