Peyronellaea curtisii

Peyronellaea curtisii (leaf scorch) is a fungal plant pathogen first described by Miles Joseph Berkeley and received its current name in 2010.

[4] It is a cause of leaf blotch, and its substrates include Narcissus, Galanthus and Hippeastrum.

[5] Peyronellaea curtisii causes red-brown spots on leaf tips of Narcissus[6] and other members of the family Amaryllidaceae; this gives them a scorched appearance that is easily mistaken for frost damage.

[7] On hippeastrum bulbs the fungus causes red spots that may develop into soft, sunken patches.

Leaf scorch fungus can also affect other members of the Amaryllidaceae, including Amaryllis, Crinum, Nerine, Sprekelia and Sternbergia.
