Silene dioica
''Silene dioica'' ( syn. ''Melandrium rubrum''), known as red campion and red catchfly, is a herbaceous flowering plant in the family Caryophyllaceae, native throughout central, western and northern Europe, and locally in southern Europe. It has ...
''. The fungus is the cause of anther-smut disease, which results in fungal spores replacing the pollen in the anthers. The species that most resembles ‘’M. silenes-dioicae’’ morphologically is ''
M. lychnidis-dioicae''.
