Diaporthe angelicae

Diaporthe angelicae is a fungal plant pathogen. This species is known as the causative agent of carrot umbel rot (Daucus carota), a serious disease affecting seed crops. The association of this species with damage to carrot seed crops was first documented in France between 2007 and 2011. Genetically, Diaporthe angelicae belongs to the genus Diaporthe, but was previously known as Sphaeria angelicae. Diaporthe angelicae, was transferred to the genus Diaporthe where it was previously located in the genus Diaporthopsis under the taxon Diaporthopsis nigrella. This pathogen has a fairly wide host range, but it mainly affects plants of the Apiaceae family, including Pastinaca sativa, Petroselinum crispum, Anethum graveolens, and Daucus carota. Wild umbellifers are also susceptible to the pathogen. Infections caused by Diaporthe angelicae have been recorded in several genera, including Angelica, Anthriscus, Daucus, and Eryngium....read more on Wikipedia.
