Lactifluus subg. Lactariopsis (Russulales/Basidiomycota) from Brazilian tropical forests

Botany, Volume 101, Issue 12, Page 570-581, December 2023.
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.
