| Popis: | In this study, taxonomic and phylogenetic analyses of Junghuhnia were performed. Three new species were characterised according to morphological characteristics and molecular phylogenetic analysis using ITS and nLSU sequences. They are J. austrosinensissp. nov., J. nandinaesp. nov. and J. subcollabenssp. nov.Junghuhnia austrosinensis is characterised by resupinate, thin basidiomata with white to buff-yellow hymenophore, small pores (9–11 per mm), clamped generative hyphae possessing hymenial cystidia, ellipsoid basidiospores (2.5–3 × 1.7–2 µm) and growth on fallen bamboo or angiosperm branch. Junghuhnia nandinae is characterised by resupinate basidiomata with pink to salmon pores and a distinct white margin, clamp generative hyphae, interwoven tramal hyphae, ellipsoid basidiospores measuring 2.6–3.2 × 1.8–2 µm and growth on Nandina domestica. Junghuhnia subcollabens is characterised by resupinate basidiomata with pale salmon to brownish vinaceous hymenophore, small pores (10–12 per mm), generative hyphae with simple septa and clamp connections, interwoven tramal hyphae, lunate basidiospores measuring 2.9–3.4 × 1.6–1.8 µm and thriving on rotten wood of angiosperms. |
