Species of fungi colonizing dying plants of Alpine lady-fern (Athyrium distentifolium Tausch ex Opiz) in the Karkonosze Mountains

Abstract

Phytopathological research was conducted in Karkonosze National Park in 2016-2017. The total of 17 isolates belonging to 13 fungal species and one taxa of fungi were isolated during the mycological analysis of infected tissue. Botrytis cinerea was identified in the samples representing each type of symptoms such as tissue discolorations, narrowing and nerve fractures. B. cinerea accounted for more than 50-60% of all fungi isolated.
