I have some Ornithogallum umbellatum clumps badly affected by this in
my naturalised-in-grass patch, but (touch wood!) only those. A Web
search is, shall we say, uninformative and my pest book implies that
it is a problem mainly in wet conditions (e.g. the West Country, and
everywhere this year).

Does anyone know anything more about it, especially which of the
Liliaceae are most vulnerable? There are some I should regret losing.

Nick Maclaren.
