 Scientific Name: Hyphodontia formosana

Hyphodontia formosana Sheng H. Wu & Burds., Acta Bot. Fennica 142: 91. 1990.

 Description: Basidiocarp effuse, ± adnate, loose-membranaceous, soft, porose-reticulate in young parts, 100-200 µm thick in section (aculei excluded). Hymenial surface Pale Olive-Buff, Ivory Yellow, Marguerite Yellow, or whitish, odontioid, not cracked; margin concolorous or paler, thinning, arachnoid-byssoid. Aculei separate or occasionally fused, 7-10 per mm, conical to subulate, 50-150 × 35-70 µm. Hyphal system monomitic; hyphae simple-septate. Subiculum indistinctly bi-layered. Basal layer with dense to compact texture, up to ca. 20 µm thick, sometimes indistinct; hyphae horizontal, colorless or subcolorless, sometimes agglutinated. Medullary layer constituting main part of subiculum, with loose texture; hyphae ± vertical, ramified at right angles, colorless or subcolorless, distinct, straight, 2.2-4.8 µm diam., with 0.4-0.8 µm thick walls, sometimes covered with scattered crystals, anastomoses occasional. Hymenial layer with rather dense texture. Trama with denser texture than subiculum; hyphae fairly vertical, slightly projecting and ±encrusted at their aculeal apices. Cystidia variably abundant, immersed or projecting, not encrusted, cylindrical, slightly flexuous, 35-50 × 6.5-10 µm, thin- or slightly thick-walled. Basidia short-clavate or subutriform, 12-20 × 5-7 µm, usually guttulate, with four small sterigmata. Basidiospores broadly ellip-soid, smooth, thin-walled, usually with one to several oil-drops, 5.5-7 × 4-5 µm, IKI-, CB-.

 Note: This species is distinct in having simple-septate hyphae. The cystidia of this species are variably abundant. According to the collection data, H. formosana appears to play an important role in decaying angiosperm debris in subtropical Taiwan.
