Novelties in Lactifluus subg. Gymnocarpi (Russulales, Basidiomycota) from Brazilian tropical forests

Lactifluus subg. Lactariopsis is a well-supported group of milkcaps occurring predominantly in tropical and subtropical ecosystems. This subgenus contains agaricoid and pleurotoid representatives and is the only group with members containing a secondary velum. The results of taxonomic and phylogenetic research into Lactifluus subg. Lactariopsis collected in Brazilian tropical forests (Amazon, Atlantic Rainforests, and Caatinga biomes) of the North and Northeast is presented here. Two new species are described: Lf. aurantioceraceus in sect. Neotropici, and Lf. reniformis in sect. Multicipites, newly delimited here . In addition, Lf. neotropicus has had its distribution expanded to the Caatinga biome, Lf. dunensis was confirmed in Lf. sect. Neotropici with new records from French Guiana, and Lf. annulifer was re-collected from the type locality. A combined dataset of nuclear rDNA internal transcribed spacer region and nuclear large subunit amplified sequences was analyzed and, based on its phylogenetic hypothesis, the two novel taxa and the new section were confirmed .

Brazil has a rich biodiversity, but many species remain to be discovered, studied and cataloged. In the Paraíba State, taxonomy studies on agaric fungi are still infrequent. Thus, this present work carried out a bibliographic review of fungal species belonging to orders Agaricales, Boletales, Cantharellales Gomphales and Russulales from the Paraíba State previously described or mentioned, because the knowledge about the fungal diversity in the region still remain disaggregated and poorly known. Thus, we organize and present information about the geographic distribution of the taxa in this checklist format. For the compilation of the results, for each species we present the published herbarium numbers and their respective citations. As results, we found 79 taxa belonging 41 genera, 22 families and five orders occurring in areas of the Atlantic Forest and Caatinga. So, this review is extremely important for the dissemination of the valuation of the State’s biodiversity providing information about our Brazilian biomes.
