Abstract
Two new species of Lepiota (L. squamulodiffracta and L. sosuensis) and a new record (L. subgranulosa) are described based on collections made in the Dominican Republic. The phylogenetic position of the species based on nrITS data is analyzed and discussed. L. squamulodiffracta belongs in section Lepiota, and it is characterized by the velar patches on pileus split up into numerous minute squamules, striate-sulcate pileus up to the center, and penguin-shaped spores. L. sosuensis has overall white basidiocarps, dextrinoid and metachromatic spores, trichodermial pileus covering, and rare clamp-connections. L. subgranulosa stands out morphologically by the spurred spores with one or several protuberances that give the spores an irregular outline.
