ABSTRACT: A rust disease caused by Uropyxis daleae (Dietel & Holw.) Magnus was registered on the natural population of Dalea pennelli (Mac Bride) Mac Bride var. chilensis Barneby in the highland near the Andes in the northernmost of Chile. This pathogen shows uredinia with the presence of paraphyses and features, larger urediniospores and teliospores than U. daleae (Dietel & Holway) Magn. var. daleae. Based on morphological combined with 28S sequence analysis, we propose this pathogen as a new fungal variety: U. daleae var. socoromensis. This is the first report of Uropyxis daleae var. socoromensis attacking D. pennelli var. chilensis in Northern Chile.
