在2009年，几个重点石楠占主导地位的E。伞形花在埃斯特雷马杜拉东部（西班牙西南部）的一个自然保护区Villuercas山区出现了衰退和死亡。受影响的总面积为10公顷。2011年春季，对E.收集表现出枯死和死亡的伞形科植物。根据形态特征、培养特征、ITS序列分析和致病性测定，初步鉴定其为肉桂疫霉。这被认为是E. umbellata作为肉桂疫霉的天然寄主。
During 2009, several foci of heathlands dominated by E. umbellata showed decline and mortality in the Villuercas Mountains, a protected natural area in eastern Extremadura (southwestern Spain). A total area of 10 ha was affected. During spring 2011, roots and rhizosphere soil samples from E. umbellata plants exhibiting dieback and mortality were collected. Based on morphological and cultural characteristics, sequence analysis of the ITS and pathogenicity tests, the causal agent was identified as P. cinnamomi. This is thought to be the first report of E. umbellata as a natural host of P. cinnamomi.
