　Description： Basidiocarp effuse, adnate, floccose, 40-120 μm thick in section (projecting cystidia excluded). Hymenial surface Pale Olive-Buff or whitish, smooth, pilose due to projecting cystidia, rarely cracked; margin concolorous, rather determinate ot thinning, not differentiated. Hyphal system monomitic; hyphae nodose-septate. Subiculum indistinctly bi-layered. Basal layer up to ca. 15 μm thick, sometimes not distinct, composed of horizontal hyphae. Medullary layer with loose texture; hyphae vertical or horizontal, ramified at right angles, colorless, distinct, fairly straight, 1.5-3.2 μm diam., with 0.4-0.7 μm thick walls. Hymenial surface with rather dense texture; hyphae fairly vertical, ramified at narrow angles, colorless, narrower and with thinner walls than those of subiculum. Hymenium and subhymenium IKI brownish, CB+. Cystidia numerous, projecting for approximately half their lengths, Colorless, subulate, covered with two rows of ribbon-shaped ornamentations, 40-80 × 2.5-4 μm, with ca. 0.8 μm thick walls, apically thin-walled, ± CB+. Basidia utriform or suburniform, 13-19 × 4.8-6.2 μm, 4-sterigmate. Basidiospores fusiform with slightly sigmoid bend, smooth, thin-walled, usually with two or more oil-drops, (10.5-) 11.2-13.8 (-15) × 2-2.8 (-3.2) μm, IKI-, CB-.

　Note： The size and morphology of the basidiospores are important features for separating different species in Subulicystidium (Oberwinkler 1977, Liberta 1980). The basidiospores of this collection agree well with the typical S. longisporum.
