description: <i>Laetiporus versisporus</i> (Lloyd) Imazeki, Bulletin of the Tokyo Science Museum 6: 88 (1943) Hierarchy: Basidiomycota, Polyporales, Fomitopsidaceae Specimens examined: KOREA, Seoul, Jongmyo shrine, 37°34 <i>ʹ</i> 30 <i>ʺ</i> N, 126°59 <i>ʹ</i> 32 <i>ʺ</i> E, 23 Jul 2015, Hyun Lee, Young Woon Lim, SFC20150723-24 (GenBank accession No. MF 445228), on the live stem of <i>Quercus</i> spp. <i>Basidiocarps</i> annual, laterally substipitate, sometimes imbricate. <i>Pileus</i> dimidiate to flabelliform, 70-210 mm, surface glabrous, azonate, radially furrowed, vivid yellow (3A8) to deep orange (5A8) when fresh, becoming paler in age. Pore surface pale yellow to yellow, pores angular, 4-5 per mm, with entire dissepiments that easily torn. Hyphal system dimitic, clamp connection absent. Generative hyphae in context hyaline, thin-walled, sometimes branched, 7-11 μm in diameter. Skeletal hyphae in context thick-walled, much branched, 8-16 μm in diameter. Generative hyphae in tube hyaline, thin-walled, 2.5-4 μm in diam. Skeletal hyphae in tube thick-walled, solid, 2-5 μm in diameter. <i>Cystidia</i> absent. <i>Basidia</i> 14.8-18.0- 21.3 × 6.1-6.7-7.8 μm, clavate, 2 or 4-spored, simple septate at the base. <i>Basidiospores</i> 5.3-6.0-7.2 × 4.4-5.1- 5.2 μm, Q = 1.0-1.2-1.3, globose to broadly ellipsoidal. Remarks: <i>Laetiporus versisporus</i> used to be misidentified to <i>L. sulphureus</i> in Korea for a long time because of similar morphology. In the Indexfungorum (http://www. indexfungorum.org/), <i>L. versisporus</i> is also recorded as a synonym of <i>L. sulphureus</i>. However, recent phylogenetic studies showed that <i>L. sulphureus</i> and <i>L. versisporus</i> are different species (Ota <i>et al.</i>, 2009; Song <i>et al.</i>, 2014). Moreover, European <i>L. surphureus</i> differs from <i>L. versisporus</i> by more ellipsoidal basidiospores. Sometimes <i>L. versisporus</i> makes anamorphic form of basidiocarp which has brownish and powdery pileus (Ota <i>et al.</i>, 2009).
