Abstract

Cultivated gentian (Gentiana scabra var.buergeri) has been seriously damaged by pink root rot since the 1970s. Diseased plants finally collapse after wilting and stunting. More than 40 fungal genera were found to be associated with roots of mature and immature diseased plants or seeds. Among these fungi,Pyrenochaeta gentianicola sp. nov. andP. terrestris were almost always associated with the diseased plants. Their morphologies and temperature responses were compared, and their pathogenicity was also demonstrated by artificial inoculation tests.
