Magnus was registered on the natural population of <i>Dalea pennelli</i> (Mac Bride) Mac Bride var. <i>chilensis</i> 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 <i>U. daleae</i> (Dietel & Holway) Magn. var. <i>daleae</i>. Based on morphological combined with 28S sequence analysis, we propose this pathogen as a new fungal variety: <i>U. daleae</i> var. <i>socoromensis</i>. This is the first report of <i>Uropyxis daleae</i> var. <i>socoromensis</i> attacking <i>D. pennelli</i> var. <i>chilensis</i> in Northern Chile.展开更多
