Abstract
Three new species of Leucocoprinus (Lc. tephrolepis, Lc. parvipileus, Lc. domingensis) are described, based on material from the Dominican Republic and the US Virgin Islands. These species belong in the Lc. heinemannii species complex, based on their morphological and molecular characteristics. The type collection of Lc. heinemannii was sequenced, and we confirm the tropical distribution of this species originally described from Italy. We discuss the problematic taxonomy of dark-centered species of Leucocoprinus, including the application of the names Lepiota montagnei, Lepiota atrodisca, and Lepiota phaeosticta.
