Olive (Olea europaea L. var. sativa) is one of the most economically important tree crops grown in the Mediterranean basin. Arthrinium Kunze ex Fr. (teleomorph: Apiospora Sacc.) is a widespread fungal genus, and Arthrinium marii Larrondo & Calvo is a ubiquitous species, found in algae, soil, plants, and agricultural communities. A. marii was isolated from olive trees showing dieback from orchards located in Andria and in Fasano, Brindisi (Apulia, southern Italy) and identified based on morphological features and molecular analysis of four genomic regions (ITS, TUB2, TEF1, and LSU). Two-year-old olive plants artificially inoculated with three representative A. marii isolates showed complete dieback within 6 months, and the fungus was reisolated, satisfying Koch's postulates. This is the first report of A. marii causing dieback on olive trees that could represent an important threat for olive cultivation.
