Micromycetes on Austrocedrus chilensis. First record of Rebentischia from Argentina

Abstract

Rebentischia massalongii was collected growing on twigs from Austrocedrus chilensis. So far known only from the temperate zone of Europe and North America, this species is reported for the first time from Argentina and the Southern Hemisphere. The type specimen of R. costi, a species described from Brazil, was re-examined and is here considered an authentic species. A key to the accepted species of Rebentischia is provided.
