ABSTRACT=<p>Phylogenetic and morphological analyses on samples of <italic>Fistulina</italic> from East Asia and North America were carried out, and two new species were described, namely, <italic>Fistulina americana</italic> and <italic>Fistulina orientalis</italic>, both previously known as <italic>Fistulina hepatica</italic>. The former is characterized by lateral stipitate basidiocarps, relatively small pores (7–8 per mm), a monomitic hyphal system with both clamp connections and simple septa, and ellipsoid basidiospores of 4–4.8 × 3–3.3 μm, and the species has been found on <italic>Quercus</italic> in North-East USA. <italic>F. orientalis</italic> is characterized by lateral stipitate basidiocarps, very small pores (11–12 per mm) with pruinose dissepiments, a monomitic hyphal system with both clamp connections and simple septa, and ovoid to subglobose basidiospores of 3–4 × 2.7–3 μm, and the species has been found on <italic>Castanopsis</italic> in East Asia. Phylogenetically, samples of <italic>F. americana</italic> and <italic>F. orientalis</italic> form two new lineages nested in the <italic>Fistulina</italic> clade.</p>
