Neocosmospora ipomoeae (Halst.) L. Lombard & Crous 2015

This fungus is widely distributed and infects eggplants, tomatoes, green pepper, ornamentals and other crops like passionfruit or Panax. It causes stem rot, dieback, wilts and other diseases, often leading to plant death. The initial symptoms on tomatoes are water-soaked lesions on the lower stems, near the collar which later turn brown. N. ipomoeae is homothallic and forms abundant orange-brown perithecia both on artificial media as well as in the lesions on diseased plants (Kwon et al., 2017).

Synonyms:
Haematonectria ipomoeae
Nectria ipomoeae
Fusarium solani var. striatum (doubtful)
Fusarium striatum (doubtful)
