Hyphomycetes and Coelomycetes fungi isolated from affected leaves and twigs of cherry laurel trees

Abstract

The aim of this work was to identify fungi occurring on leaves and twigs of Prunus laurocerasus L. Mycological observations were carried out on leaves and twigs collected from symptomatic cherry laurels growing in green areas of the Nitra town from spring to autumn in 2009–2010. Six species of microscopic fungi were isolated and microscopically identified from samples during the study period. The occurrence of some microscopic fungi in class Hyphomycetes (Alternaria alternata (Fr.) Keissl., Fusarium oxysporum Schltdl., Thielaviopsis basicola (Berk. & Broome) Ferraris, Trichothecium roseum (Pers.) Link) and Coelomycetes (Colletotrichum gloeosporioides (Penz.) Penz. & Sacc., Phomopsis sp.) has been confirmed. The most frequently found fungi included: Alternaria alternata, Colletotrichum gloeosporioides and Phomopsis sp. The fungus Fusarium oxysporum was found in examined samples relatively commonly. Only sporadical incidence of the fungi Thielaviopsis and Trichothecium was noticed.
