Yurchenko, Eugene; Xiong, Hong-Xia; Wu, Sheng-Hua
Corticioid fungi Hyphodontia anmashanensis, H. echinata, H. subclavata and H. tenuissima collected from Taiwan are reported as new to science. Hyphodontia anmashanensis and H. subclavata have ellipsoid basidiospores and inconstantly present moniliform cystidia. Diagnostic characters for the former species are a thick, densely and coarsely odontioid basidioma, whitish hymenial surface, wavy subicular hyphae and flexuous hyphoid cystidia; the latter is characterized by having minutely odontioid hymenial surface, broad leptocystidia of subclavate, cylindrical or fusoid shape, and capitate cystidia bearing caps of resinous matter. Hyphodontia echinata is featured by the projecting clusters of hypha-like cystidia, apically covered by stellate crystals, long and narrow basidia, and ellipsoid spores. Hyphodontia tenuissima resembles H. crustosa, bears cylindrical spores and subulate cystidia. It is diagnostic in having a very thin (usually about 20 μm) basidioma and fairly smooth hymenial surface. Morphology description, basidioma photographs, and line drawings of microscopical structures for each species, are provided.
