Gymnosporangium cornutum in Portugal

Abstract

This work is included in the contributions to the recording and conservation of fungi from the Portuguese Flora. Studies were carried out for several years in the Plant Protection Department, of the National Agronomic Research Station. In August 2004, a rust fungus identified as Gymnosporangium cornutum was found on Sorbus aucuparia in Serra da Estrela (Manteigas – Torre road), and the disease caused by this pathogen was severe at that location. During 2005 and 2007, G. cornutum telia were identified in Juniperus spp., in Serra da Arrábida and in Mata dos Medos/Pinhal do Rei – Almada.
