SUMMARY:

The Agaricaceae family was characterized by presenting tricholomatoid or colibioid basidiomata, but mainly pluteoides, with 25 genera distributed in the tribes Leucocoprinae, Agariceae, Lepiotae and Cystodermatae, with a wide continental distribution. However, the concept of the family has changed, including also species of secotioid and gasteroid basidiomata divided into 10 clades, including the genera Chlorophyllum and Macrolepiota. Chlorophyllum accommodates a species considered poisonous (Chlorophyllum molybdites), while Macrolepiota contains some species appreciated in gastronomy. Studies involving Chlorophyllum and Macrolepiota, despite contributing to a better understanding of species richness, are concentrated in regions such as Australia, Asia, Central and North America, but still little explored in others, such as Brazil. Therefore, the present study aimed to increase the species richness for taxa Chlorophyllum and Macrolepiota in the Northeast region of Brazil. For that, morphological studies were carried out from previously collected specimens, deposited in the herbarium Lauro Pires Xavier – JPB (João Pessoa, Paraíba). In addition, microchemical tests were performed using Melzer'sreagent and Cresyl blue in the spores, together with molecular analyzes that used the complete internal transcribed spacers ITS1 and ITS2 and 5.8S rDNA (nuc-ITSrDNA) delimited by the primers ITS1 and ITS4 and the 28S gene rDNA ligated by primers LR0R and reverse primer LR7. New species for science were described (Chlorophyllum sp.n. and Macrolepiota sp.n.). Additionally, a new record of Chlorophyllum molybdites for the Paraíba State of based on morphological and molecular analysis is also presented, contributing to the species richness of the region.
