Abstract

In order to better understand species delimitation in the Pluteus glaucotinctus species complex, we present a detailed study based on morphological and DNA sequence (nrITS + tef1) data. Pluteus glaucotinctus sensu stricto is known only from the type collection (Democratic Republic of the Congo), which is re-examined here. Four other species are recognized in this complex and described herein as new: P. izurun from Spain, P. meridionalis from Brazil, P. padanilus from India and P. thoenii from Africa. Phylogenetic analyses based on nrITS + tef1 sequence data support the recognition of all species in this complex.
