Limoni servi (Cupressus macrocarpa cv. Goldcrest) Türkiye’de kentsel peyzaj alanlarında popüler olan Cuppressaceae familyasına ait iğne yapraklı bir ağaçdır. 2021 yılının Temmuz ayında Çanakkale merkezinde özel bir mülke ait bir bahçede C. macrocarpa cv. Goldcrest bitkisinin ana gövdesinde geriye ölüm belirtileri ile birlikte kabukta uzunlamasına siyah-kahve renkli lezyonlar ve çatlaklardan sızan reçine gözlemlenmiştir. Kanserli dokuların kenarlarından yapılan izolasyonlar sürekli olarak; önce kirli beyaz, sonra bazı kısımlarda veya daha eski kültürlerde grimsi zeytin yeşili olan yoğun floccose havai miselyuma sahip düz koloniler sonuçlamıştır. Elde edilen izolatların morfolojik karakterlerine, temsilci bir izolatın ITS rDNA bölgesinin moleküler analizine ve 2 yaşındaki C. macrocarpa cv. Goldcrest bitilerinde yapılan patojenisite testlerine göre, hastalık etmeni Seiridium cardinale (Wagener) Sutton & Gibson olarak tanılanmıştır. Bu çalışma, şu anki bilgilerimize göre, Türkiye’de C. macrocarpa’da S. cardinale’nin sebep olduğu servi kanseri hastalığının ilk raporudur.

Lemon cypress (Cupressus macrocarpa cv. Goldcrest) is a coniferous Cuppressaceae tree and is popular in urban landscapes of Turkey. In July 2021, dark-brown elongated bark lesions and resin exuding cracks with die-back symptoms were observed on the main stem of young C. macrocarpa cv. Goldcrest trees in a private house garden in the central district of Çanakkale Province of Turkey. Fungal isolations made from the margin of cankers of trees consistently yielded flat colonies with dense floccose aerial mycelium that were first off-white and grayish olive-green in some parts or in older cultures. Based on the morphological characteristics of obtained isolates, molecular analyses of the ITS rDNA region of a representative isolate, and pathogenicity tests on 4-year-old C. macrocarpa cv. Goldcrest plants, the causal agent was identified as Seiridium cardinale (Wagener) Sutton & Gibson. This is, to the best of our knowledge, the first report of S. cardinale causing canker on C. macrocarpa in Turkey.
