Abstract Lulesia fallacioides (from Finland) and L. parvifallax (from Switzerland) are described as new species, based on both a morphological and molecular approach, in the L. fallax complex (Lulesia subgen. Paraclitopilus), a morphology-delimited aggregate of species sharing white basidiomes and a bitter context. Compared to L. fallax, the former differs mainly by wider spores and a gelatinized pileipellis and the latter by smaller basidiomes and shorter spores. The recently described Clitocella neofallax from China is here combined in Lulesia. New collections of L. colorata and L. solaris made in Italy and Finland have allowed us to better understand the distinctive features and/or to extend the distribution area of these recently established species. The presence of L. fallax, L. mundula and L. obscura in Finland is here molecularly confirmed for the first time. Finally, a full morphological description of L. alachuana, a North American species so far described from Florida, is provided based on ancient (holotype included) and recent collections.
