 Scientific Name: Hyphodontia niemelaei

Hyphodontia niemelaei Sheng H. Wu, Acta Bot. Fennica 142: 98. 1990.

 Description: Basidiocarp effuse, adnate, membranaceous or subceraceous, 50-150 µm thick in section (tubes excluded). Hymenial surface Cream Color, poroid, not cracked; margin paler, thinning, pruinose or arachnoid. Pores round, ca. 3 per mm; tube layer ranging from very shallow to ca. 300 µm deep, dissepiments 40-100 µm thick. Hyphal system monomitic; hyphae nodose-septate. Subiculum bi-layered. Basal layer with compact texture, up to ca. 20 µm thick; hyphae horizontal, yellowish, agglutinated, slightly thick-walled. Medullary layer constituting main part of subiculum, with rather loose to rather dense texture; hyphae ±vertical, moderately ramified, loosely interwoven, colorless, rather distinct, 2-3.5 µm diam., thin-walled, slightly thick-walled near basal layer, usually covered with scattered granular crystals. Trama with more compactly arranged and vertical hyphae than those of medullary layer. Capitate cystidial elements numerous, present in subiculum and hymenium, 20-35 × 5-6 µm, thin-walled. Subulate cystidial elements numerous, present in hymenium, some-times slightly constricted near apices, 18-28 × 4-6 µm, thin-walled. Encrusted hyphal ends can be found in older specimens, being present in hymenium, more concentrated in tube edges, scattered elsewhere, projecting. Basidia suburniform, guttulate, 17-23 × 4.5- 5.5µm, 4-sterigmate. Basidiospores broadly ellipsoid, smooth, thin-walled, usually with one or a few prominent oil-drops, 5.2-6.2 × 3.3-4 µm, IKI-, CB-.

 Note: Although very close to Hyphodontia apacheriensis (Gilb. & Cant.) Hjortstam & Ryvarden, H. niemelaei differs from it in the following characteristics: (1) narrower basidiospores, (2) capitate cystidial elements in the subiculum, instead of fusiform hyphal ends, (3) Basidiocarp perhaps with shallower tube layer.
