| Summary: | <i>Marsupella minutissima</i> was recorded for the first time outside of Japan in Jeju-do in the Republic of Korea. The new data significantly improve the knowledge of the species distribution. An analysis of the phylogenetic affinities of the species based on nuclear ITS and plastid <i>trn</i>L-<i>trn</i>F regions showed that it is resolved within the clade corresponding to <i>Marsupella</i> sect. <i>Ustulatae</i>, which is where the most morphologically similar <i>M. funckii</i> and <i>M. sprucei</i> are placed. These tree taxa are well delimited geographically. When found within the same region, such as a mountain chain, they occupy different altitudinal belts. Our results showed clear molecular delimitation; however, we failed to estimate the affinities of <i>M. minutissima</i> within the section based on the available molecular data. A description, line-art illustrations and photographs of the collected materials are provided; data on the oil bodies of the species were obtained for the first time. |
