These taxa are added to twelve previously described species known from, or reported here for the first time from, the region of study: A. advena, A. arocheae, A. brunneolocularis, A. colombiana, A. ebumea, A. farinosa, A. flavoconia var. inquinata, A. fuligineodisca, A. muscaria subsp. flavivolvata, A. polypyramis, A. sororcula, and A. xylinivolva. Amanita flavoconia var. sinapicolor is proposed to be a taxonomic synonym of A. flavoconia var. inquinata. An unusual species of Amanita subsection Vittadiniae is given the code Amanita sp. HONI and treated only in a key to regional species of Ama- nita section Lepidella. A gazetteer is provided for Costa Rican sites at which Amanita species have been collected.
