ABSTRACT In the fall of 2024, desert rose plants ( Adenium obesum ) displaying wilt and stem rot symptoms were collected in a residential garden in the State of Tocantins, Brazil. Here, we identify the pathogen causing these symptoms on desert roses, based on its morphological and molecular characteristics. Proof of pathogenicity was also performed. Neocosmospora keratoplastica was recognised as the causal agent of wilt and stem rot in desert roses. The study represents the first record of this fungus causing disease in Adenium obesum in Brazil and worldwide.
