Phylogenetic tree, species delimitation results, and morphological characterization of Antarctic Arrhenia antarctica. A. Maximum likelihood phylogenetic tree of Arrhenia based on ITS and LSU sequences. Colored bars adjacent to the phylogeny represent putative species boundaries determined by ABGD, GMYC, and PTP analyses. Bootstrap support values over 70 are shown at nodes; B. Morphological characters of Antarctic Arrhenia antarctica with field photographs of basidiomata and line drawings of microscopic structures. Abbreviations are as follows: sp = basidiospores, bs = basidia, pp = pileipellis. Scale bars: 1 cm (basidiomata); 10 μm (sp); 20 μm (bs, pp).	Figure 1.
