This study confirms the presence of seven Ganoderma species in Costa Rica and expands the distribution range of G. curtisii and G. ecuadorense to Central America.
Ganoderma species are well recognised by their significant role in the recycling of nu- trients in ecosystems and by their production of secondary metabolites of medical and biotechnological importance. Ganoderma spp. are characterised by laccate and non-laccate, woody basidiocarps, polypore hymenophores and double-walled basidio-spores generally with truncate apex. Despite the importance of this genus, its taxonomy is unclear and it includes several species' complexes with few circumscribed species and incorrect geographic distributions. The aim of this work was to provide detailed morphological descriptions together with phylogenetic analyses using ITS sequences to confirm the presence of seven species of Ganoderma in Costa Rica: G. amazonense, G. applanatum s.l., G. australe, G. curtisii, G. ecuadorense, G. oerstedii and G. parvulum. This is the first study that integrates morphological and phylogenetic data of Ganoderma from Central America and a key of the neotropical species. Besides, the distribution range of G. curtisii, previously reported from North America and G. ecuadorense from South America, is expanded to Central America.
