Geosmithia cnesini sp. nov. is a dominant symbiont of the ambrosia beetle Cnesinus lecontei collected from Croton draco in Costa Rica. This fungus is characterised by whitish colonies and penicillate conidiophores with extraordinary large catenate conidia. Graphium scolytodis sp. nov. is described here from the galleries of ambrosia beetle Scolytodes unipunctatus collected from the trunk of a fallen Cecropia angustifolia tree in Costa Rica. This species does not seem to be a nutritional mutualist but rather a stable associate of unknown function. It produces mononematic conidiophoresonly and is related to Graphium penicillioides
