Two new species of the genus Dendrothele – D. salicicola and D. bisporigera – are described. Both species occur on bark of especially old, living arborescent willows (Salix alba and S. fragilis) in Bohemia (Czech Republic). Dendrothele salicicola is characterised by tetrasterigmatic basidia with indextrinoid walls, slightly bent sterigmata and the presence of hyphidia; it is presently known from 29 localities and 7 microlocalities. D. bisporigera is chiefly characterised by bisporic basidia with dextrinoid walls, the special spores shape and content as well as by the absence of hyphidia and cystidia; it has been found at two localities to date.
