Notes: The species has been reported in many countries but may represent a species complex ( Núñez & Ryvarden 1997, Bernicchia & Gorjón 2010, Rajchenberg et al. 2021). Since Corticium cerussatum was originally described from Europe, we chose the lineage of the sample of CBS 106.54 from Netherlands to represent this species. In our phylogenetic tree ( Fig. 1 View Fig ), three samples from USA, identified as Aleurodiscus cerussatus , A. laurentianus and A. lapponicus . respectively, formed a strongly supported lineage. The three species are morphologically similar to each other and represent a species complex that needs further study.
