Abstract:
Sidera , belonging to the Rickenella clade of Hymenochaetales, is a worldwide genus with mostly poroid hymenophore of wood-inhabiting fungi. Two new species in the genus, Sidera americana and S. borealis , are described and illustrated from China and North America based on morphological and molecular evidence. They were mainly found growing on rotten wood of Abies , Picea and Pinus . S. americana is characterized by annual, resupinate basidiomata with silk sheen when dry, round pores (9–11 per mm), a dimitic hyphal system, and allantoid basidiospores measuring 3.5–4.2 × 1 μm. S. borealis is characterized by annual, resupinate basidiomata with cream to pinkish buff dry pore surface, angular pores (6–7 per mm), a dimitic hyphal system, and allantoid basidiospores measuring 3.9–4.1 × 1–1.1 μm. Phylogenetic analysis based on a combined 2-locus dataset [ITS1-5.8S-ITS2 (ITS) + nuclear large subunit RNA (nLSU)] shows that the two species are members of Sidera , and they are compared with morphologically similar and phylogenetically related species, respectively. An identification key to 18 accepted species of Sidera in worldwide is provided.
