Choreonema thuretii and Pneophyllum confervicola, two cosmopolitan species, are here recorded for the first time for the Azores. They were found during an investigation of intertidal communities in Pico Island (Azores) in the summer of 2007. Both species were found hosted in Jania rubens specimens, C. thuretii as a semi-endophytic parasite, P. confervicola as an epiphyte. They are present on other archipelagos from Macaronesia (Madeira and Canary Islands). It is likely that they have been overlooked in the Azores due to their small size and parasitic/epiphytic habit. A morphological and anatomical account is provided for both species, and it is hoped that this additional observations provided herein will alert field surveyors for their presence.
