SUMMARY:

Tylopilus sensu lato is a very diverse genus within the Boletaceae family, and due to the considerable morphological plasticity of the genus, the taxonomic and phylogenetic limits were evaluated in parts, and its infrageneric classification still remains unclear. As an example we have Tylopilus balloui, originally described for North America and comprising fungi with an orange-toned cap, white to cream to yellow pores that turn brown to the touch and a stipe with yellowish tones. Because the works are fragmented and with little content about the genus, reanalysis using, in addition to morphology, moleculares tools is necessary. The objective of this work is to analyze the species richness of T. balloui sensu lato collected in the states of Paraíba and Rio Grande do Norte and to interpret which morphological characteristics can be used in the delimitation of cryptic species for a better understanding of the characters of this group. For this study, six specimens were studied, two belonging to specimens collected in the Parque Estadual das Dunas do Natal and the other four in the REBio Guaribas (area of SEMA II), which are conservation units considered areas of coastal plains and tableland forests. Morphological and phylogenetic analyzes followed the traditional methodology for macrofungi. After ITS analysis, T. dunensis was identified, constituting a new record for Paraíba, and two new species. One of these species is considered semi-cryptic species with sympatric speciation with T. dunensis. And the other is a new well-defined taxon based on phylogenetic and morphological evidence. The works will also include color photographs of the macro and microscopic characteristics and illustrations of the specimens, and deposited in herbariums.
