Studies in Amanita (Amanitaceae) of Central America. 1. Three new species from Costa Rica and Honduras

摘要

Amanita conara, A. costaricensis, and A. garabitoana are proposed as new species. 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. eburnea, 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. HON1 and treated only in a key to regional species of Amanita section Lepidella. A gazetteer is provided for Costa Rican sites at which Amanita species have been collected.
