Two new species and a new record of Lepiota (Basidiomycota, Agaricales) from the Dominican Republic

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.
